Amiel's Graphing Post

1.)Bar graphs - Bar graphs are best for comparing data across categories.
Advantages:
Represents data easily
Easy to make
Gives you results easier.
Disadvantages:
Graph categories can be reordered to emphasize certain
effects
Use only with discrete data
Limited space for labeling with vertical bar graphs
2.)Double graphs - Double Bar Graphs are good for comparing two sets of data
across categories.
Advantages:
Great for comparing two sets of data.
Represents data easily
Disadvantages:
Not all intervals might work.
3.)Circle graphs- Circle graphs are best for comparing categories to the whole using percents.
Advantages:
Compares categories in parts of a whole using percents.
Disadvantages:
Its hard to get the percents of the categories.
4.)Line graphs- Line are best for showing changes over time.
Advantages:
Shows changes overtime.
Disadvantages:
Its harder to identify the intervals
5.) Pictographs - Pictographs are best for comparing data that can be
easily counted and represented using symbols.
Advantages:
Easy to read
Disadvantages:
They all have to be the same size.
There are three ways a graph can be misleading.
1.) Changing the size of the bars - Making it look 3D, Making one look much
bigger than the other.
2.)Changing the scale - Making a break in the Y-axis.
3.)Making one picture look bigger.
2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would
show the information accurately?
2b) If you were selling Pizza Subs would you
continue? How does your graph explain your answer.
2A)I would use a pictograph so the data can be easily seen by percents, and it would also show how much people are buying.
2B)They should continue selling because there are many people buying pizza subs.
A.)Below you see 2 different examples of graphs showing healthy choices
sold at thecanteen. If you had to convince Mrs Mota that we should continue
sellinghealthy choices which graph would you choose?
B.) Change each graph so that your information looks even MORE impressive.
You may not change the data just the graphs.
A.) I would prefer a bar graph and circle graph because judging by the height of the bars amd the size of the collumns on the circle graph more and more people are eating healthy food choices.
B.) Modified Graphs
Note: All Graphs are created by me at createagraph.gov so don't accuse me of copy and pasting these graph just because they are perfect.

Types of Graphs:



  1. Bar Graphs
Advantages:



  • visually strong

  • can easily compare two or three data set

Disadvantages:



  • graph categories can be reordered to emphasize certain effects

2. Double Bar Graph

Advantages:


  • it's good for comparing two sets of data, to see the difference of the two data
Disadvantages:


  • the intervals can be hard to find where the exact bar is

3. Line/double line graph

Advantages:


  • is best for showing data overtime

  • also good for finding the trend

Disadvantages:



  • depending on the interval, finding the exact data can be difficult unless it is shown

4. Circle Graph

Advantages:


  • visually appealing

  • shows percent of total for each category

Disadvantages:



  • no exact numerical data

  • hard to compare two sets of data

  • the "other" category can be a problem

  • total unknown unless specified

  • best for 3-7 categories

  • use only with discrete data

5. Pictograph

Advantages:


  • easy to read

  • visually appealing

  • handles large data sets easily using keyed icons
Disadvantages:



  • hard to quantify partial icons

  • icons must be of consistent size

  • best for only 2-6 categories

  • very simplistic


Distorting the Graphs:



  1. Distorting the scale - a break in the y-axis - can be showed as:

  2. Distorting the visual(pictograph)



  3. Distorting the size of the bars






Questions:


2. a) A bar graph and a line graph can show the data more accurately.


b) Yes, I would continue because the sales go up each week and both graphs show a trend.



4. I would choose the line graph because it shows the trend increasing.


a)



Carlo's Graphing Post
1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph



Bar Graph
Advantage- You can easily compare it two or three data.

Disadvantage-
Graph categories can be reordered to sets
emphasize certain effects.



Double Bar Graph
Advantage- Double Bar Graph is best for comparing two sets of data.

Disadvantage-The disadvantage of double bar graph is the interval
are hard to find and plot graph.





Circle Graph

Advantage- It's good for showing percent of total for each of the cate
gories.

Disadvantage- Is that the percents are really close and the categories.








Line Graph
Advantage- Line Graph is good for comparing
multiple continuous data sets easily.
Disadvantage- One disadvantage is that it can only use with continuous data.







Picto Graph

Advantage- Pictograph is good for comparing data that can be easily counted and represented using symbols.
Disadvantage- One disadvantage for pictograph is that its hard to tell if the picture are half or 1/3.

2. How can graphs be misleading. Show 3 ways.







1) You can make the graph wider or 3D, so the people might think that it's more popular the the
other graph.


2)Another way of misleading the graph drawing different sizes for pictograph.

3) Last way of misleading the data is distorting the graph or scale.


2a) The following chart shows Pizza Sub Sales over a month.
What 2 graphs would show the information accurately?

Answer: I would use a Bar Graph and a Line Graph.

2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

Answer: Yes I will keep on selling pizza subs because people are more often buying pizza subs and the trend is getting higher everybody.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had
to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

Answer
: I think that I would use line graph because it show's the change data over time.


4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.




JB's Graphing Post

Bar Graph
Advantage - Best for comparing data across categories.
Disadvantage - If the numbers are close by, it would be hard to compare.

Double Bar Graph
Advantage - Best for comparing two sets of data across categories.
Disadvantage - It could get confusing with both of them together.

Circle Graph
Advantage - Best for comparing categories to the whole using percents.
Disadvatage - It would take a while to find the percent and how big it would be in the circle.

Line Graph
Advantage - Best for showing changes in data over time.
Disadvantage - It only shows the trend.

Pictograph - Best for comparing data that can be easily counted and represented using symbols.
Disadvantage - You have to make the pictures the same size.




-If theres a break in the y-axis.
-If the pictures in the pictograph are different sizes.
-If the bars are different sizes.




2a) The 2 graphs I would use is a bar graph and a line graph.

2b) I would keep selling it because it gets higher every week, you could see it get higher in the line graph trend.




4) I would choose the line graph because it shows the trend that it goes up.


Sorry Mr.Harbeck, cant do the rest! Im using my moms phone to do this.
I dont know what this would look like on the computer.

Mikyala's graphing post

in this post you will find the questions that were asked on the post we were asked.
here goes everything i got!!!!!
1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph.
advantage for the circle graph
the advantage for the circle graph is it shows the % of the whole to half set of numbers.
disadvantage for the circle graph
the disadvantage for the circle graph is the piece that the set of data is on for example. when you put in your graph 23% then go and have to do 25% the shapes look to the same to recognize the number it actually is.
advantage for the bar graph
the lines in the bar graph are visually better and they look neat and more organized.
disadvantages for the bar graph
graphs can be misconception on it and emphasize the ! bar more than the other.

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph

Data can be presented using bar graphs, double bar graphs. circle graphs, line graphs, and pictographs.

The advantage of using a bar graph is that it compares data across categories and you can clearly see the comparison from each category . One disadvantage of using a bar graph is that some of the numbers can be hard to identify.

One advantage of using a double bar graph is that you can compare two sets of data on one graph. A disadvantage is that is can only be used when you compare two sets of data.

An advantage of using a circle graph is that it shows the percents of each category. One disadvantage is that it is harder to make and you have to find the percent of each number.

One advantage of using a line graph is that it shows data comparing over time, a disadvantage is that it could be hard to identify the exact number on the graph.

An advantage of using a pictograph is that the data is represented by symbols a disadvantage is that it can be harder to see if a symbol is cut in half.

2. How can graphs be misleading. Show 3 ways.

In a pictograph, if you make the pictures look bigger on one of the objects, it would look more important compared to the other ones.

If you make one of the bars on a bar graph wider, 3D or colour it in, it can appear as the most important one.

If there is a break in the y-axis , it can make the data appear bigger or smaller then it really is.

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

I think a bar or line graph would be best to represent the information most accurately.




2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

Yes, I would continue selling pizza subs because the graph shows the pizza subs getting greater.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

I would choose the line graph because it shows the data going up over time.


4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.

1. Use your notes to list the different kinds of graphs. Please list the advantages and disadvantages of each graph.


Bar graphs:

- An advantage of using a bar graph is: You can clearly see the difference between the categories, like which one is bigger/smaller.

- A disadvantage of using a bar graph is: Depending on the scale, the number of one category might be hard to identify.

Double bar graphs:

- An advantage of using a double bar graph is: You can compare two sets of data at the same time.

- A disadvantage of using a double bar graph is: It can only be used when comparing two sets of data.

Circle graphs:

- An advantage of using a circle graph is: It shows the category compared to a whole.

- A disadvantage of using a circle graph is: You have to find the percent of each category.

Pictographs:

- An advantage of using a pictograph is: It's good for comparing data that is easily counted and represented using symbols.

- A disadvantage of using a pictograph is: It's hard to tell if one picture is cut in half or cut in a different way.



2. How can graphs be misleading. Show 3 ways.

- In a bar graph, you can make one bar wider, 3D or you can color it in to make it seem more popular.


- You can put a break in the y-axis to make the data seem smaller/bigger than it really is.



- You can make the pictures in the pictograph bigger or smaller than the others to also make it seem smaller or bigger than it is.


2. a) The following chart shows Pizza Sub sales over a month. What 2 graphs would show the information accurately?


- I think that a bar graph or a line graph would show the information accurately.





2. b) If you were selling pizza subs would you continue? How does your graph explain your answer.



- Yes I would continue to sell pizza subs because every week the sales of the Pizza Subs are getting greater. My graph explains my answer because it shows how overtime the sales get greater.


4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?


- I would choose the line graph because it used a data set overtime.



4. a) Change each graph so that so that your information looks even MORE impressive. You may not change the data just the graphs.




Jackie's Graphing Post

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph.

The types of graphs we learned was...

  • Line graphs
Advantages: A line graph's advantages are that it is useful an best known for comparing a set of data overtime. For example how long you worked everyday for a year. It is also good for finding the trend. Like if you graph went January, February, March. The next month would be January and the rest all over an over again.

Disadvantage: The disadvantages of a line graph is that depending on the intervals the data will be harder to identify and you will not exactly know where the dot is unless it is exactly on the next line.



  • Bar Graph
Advantages: The advantages of a bar graph is that it is very good for comparing data so you can easily see the comparison between other bars.

Disadvantages: The disadvantages of a bar graph is that it is pretty much the same concept as a line graph, the intervals can not be that accurate to identify and hard to see exactly where the bar is at.


  • Double Bar Graph
Advantages: The advantages of a double bar graph is that it is good for comparing two sets of data. So you can see the comparison between two of the data.

Disadvantages: The disadvantages of a double bar graph is that the intervals can be hard to find out exactly where the dot or bar is.

  • Circle Graph
Advantages: The advantages of using a circle graph is that it is best known for comparing part to the whole, and using percentage.

Disadvantages: The disadvantages of a circle graph is that if the percentages are really close it is hard to tell what is bigger or if it is the same, another disadvantage is that if the percentage is not printed or placed under a category it is hard to name exactly what the actual percentage is.


  • Picto Graph
Advantages: The advantages of a picto graph is that it is good for giving you a comparison of data that can easily be counted and represented using symbols.

Disadvantages: The disadvantages of a pictograph is that it is hard to see if a symbol is cut in half or 1/3 etc.

















  • Double Line Graph
Advantages: The advantages of double line graphs is that it is very good for comparing two sets of data just like a double bar graph, but this is used for two sets of data overtime and finding the trend.

Disadvantages: The disadvantages of a double bar graph is pretty much the same as the double bar graph, it is hard to exactly pin point where the bar or the dot is specifically because the intervals cannot be that accurate.





2. How can graphs be misleading? Show 3 ways.

Graphs can be misleading if......

  • You make one of your graphs wider or 3D so it might make people think that its doubled of some sort and to show that it is popular.


  • You make your pictures in a picto graph different sizes to show that you can show if you really like it or if it is important of some kind.


  • You add the break in the y-axis to make the lowest amount of data seem smaller than usual and make the higher pieces of data seem larger than usual.


2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

Answer: I think that a bar graph and a line graph is the best to use and the most accurate to use for displaying this set of data.


2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

Answer:Yes, I would because the Pizza Subs' sales are becoming greater and greater so I would receive more money and pizza subs will become more popular. My graph explains my answer because you can see how it starts off small then it keeps growing greater and greater as is goes overtime.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?









Answer: I would choose a line graph because it uses a set of data over time with in 3 months which were September, October, and November. Also because it clearly shows that people are buying more and more healthy foods, as you can see in the trend.

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.



I made my graph more impressive by making the interval's range get closer together so it is more accurate to see where the dot is.
