1.)Bar graphs - Bar graphs are best for comparing data across categories.

Advantages:

Represents data easily

Easy to make

Gives you results easier.

Disadvantages:

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

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.

Disadvantages:

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.

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.

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
