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...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.

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.

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.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.

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.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.
