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

Bar graph Advantage: best for comparing data across categories

Disadvantage: depending on the scale/intervals it may be difficult to identify the exact number of data

Double bar graph advantage: best for comparing two sets of data across categories

Disadvantage: depending on the scale /interval it may be difficult to identify the exact number of data

Circle

How can graphs be misleading. Show 3 ways.

1.Distorting the scale(putting a break on y-axis)

2.Distorting the visuals(make the symbol larger than the rest)

3.distorting the size of the bars(make 1 bar wider or put area)

3a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

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.bar graph and line graph

**graphs**are best for comparing categories to the whole using percent**disadvantage**:it will take long time to construct it**Line graphs advantage**:best for showing changes in data overtime and show the trend**Disadvantage**-it can only be use to show data over timeHow can graphs be misleading. Show 3 ways.

3b) If you were selling Pizza Subs would you continue? How does your graph explain your answer. Yes,i will continue selling pizza subs because at my graph it shows that pizza subs that are sold increase every week

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.bar graph and line graph

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