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

A Pictograph uses pictures to represent a quantity of data values in order to decrease the size of the graph. A key must be used to explain the pictures.

Advantages: Easy to read, Visually appealing ,Handles large data sets easily using keyed Pictures

Disadvantages: Hard to quantify partial pictures Icons must be of consistent size Best for only 2-6 categories Very simplistic

A Line graph displays data as a percentage of the whole. Each pie section should have a label and percentage. A total data number should be included.

Advantages: Visually appealing Shows percent of total for each category

Disadvantages: No exact numerical data Hard to compare 2 data sets "Other" category can be a problem Total unknown unless specified Best for 3 to 7 categories Use only with discrete data

A bar graph displays discrete data in separate columns. A double bar graph can be used to compare two data sets. Categories are considered unordered and can be rearranged alphabetically, by size, etc.

Advantages: Visually strong Can easily compare two or three data sets

Disadvantages: Graph categories Use only with discrete data can be reordered to emphasize certain effects

A Double bar graph are best for showing two sets of data across catorgies.

Advantages:double bar graph gives two or more pieces of information one graph

Disadvantges:. However, if a group vertical bar graph has too many series of data, the graph becomes cluttered and it can be confusing to read.

A Circle Graph displays data as a percentage of the whole. Each pie section should have a label and percentage. A total data number should be included.

Advantages:Visually appealing Shows percent of total for each category

Disadvantages:No exact numerical data Hard to compare 2 data sets "Other" category can be a problem Total unknown unless specified Best for 3 to 7 categories Use only with discrete data

How Graphs Can be Misleading?(three ways)

A pictograph can be misleading when it is not drawn carefully and accuratley

A bar graph can be misleading when there is a break in the y-axis which means that one of the intervols is worth more than the others making then un even.

A bar graph can be misleading when one of the bars is colored differently.**2. aThe following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?**

bar graph & line graph.**2.b f you were selling Pizza Subs would you continue? How does your graph explain your answer.**

A line graph would show that every week the sales get better. Of course I continue to keep selling pizza subs.**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? **

Pictograph and Line Graph.

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