Unit 9 lesson 12 great review on graphs!
Bar graph• Compares data that is countable
Double bar graph
• Compares two sets of data in one graph
Frequency tableKeeps track of how many times things occur… used to
create other graphs (histogram)
People in your Household

Histogram
• Compares the frequency of the data• Bars touch
Line plot• Shows how data groups together at certain
points
Mon. Tues. Wed. Thurs. Fri Sat Sun
= 2 people

Line graph
• Shows change over time – prices, temperature
• Used when investigating trends
Venn Diagram• Shows data sorted into categories, and shows
if they overlap or fit into more than one category

Circle graph
• Compares to the WHOLE!• Percentages out of 100%• To find how many surveyed add up the
numbers!
Quick Check: Match Up!
