1. Use your notes to list the different types of graphs.

Please list the advantages and disadvantages of each graph.

Bar graph

Advantage- It shows who has the most or who has the least

.

Disadvantage- intervals can be changed to make some bars bi

gger than the other one even though they're the same close.

Double Bar graph

Advantage- Good for comparing two data across categoryDisadvantage- Intervals might not be that accurate and makes the graph wrong

Line graph

Advantage- Good for comparing data overtime

Disadvantage- You can only use it to compare data overtime

Pictograph

Advantage- Easy to see the comparison between the data.

- you can count the pictures easily

Disadvantage- You can't show exact amount because you cant draw thi

ngs in half.

Circle graph

Advantage- Good for comparing the data with the whole

Disadvantage- Takes too long to make and you can only use percentage.

You can make a pictograph misleading by making the picture big

ger than the other one.

You can make a bar graph misinterpreted by doing the "

zig zag" on the y-axis

You can misinterpret a line graph by making the numbers on the y- axis far away from each other.

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs woul

d show the information accurately?

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.

Yes,because more people are buying it over time and if I continue selling Pizza Subs I might earn alot of money.

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 gr

aph would you choose?

I would show Mrs.Mota the line graph because its more accurate than the pictograph and

I would show Mrs.Mota the line graph because its more accurate than the pictograph and

it shows that more healthy snacks are being bought overtime.

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