Compare Two Sets of Data Within a Graph

If one variable increases as the other variable decreases, there is said to be a __________ __________.

• Negative association

• Positive association

• Linear association

• Boundary line

A _____ is a set of disconnected data

points plotted on a coordinate plane. It allows

us to investigate connections between two

variables.

• Segmented Bar Graph

• Scatter Plot

• Two Way Table

• Relative Frequency

A _____ compares two

categories within a data set. The whole bar

represents all the data within one category.

Then, each bar is separated into parts

that show the percentage of each

part in the second category.

• Segmented Bar Graph

• Two-way table

• Relative Frequency

• Scatter plot

If one variable increases as the other variable increases, there is said to be a _________ __________.

• Positive association

• Negative association

• Boundary point

• Cluster

When comparing the spread of two data sets using box plots, which component should be examined?

• The length of the whiskers

• The size of the box

• The position of the median

• Both A and B

A graph that shows the values of two variables on a coordinate plane. It allows us to investigate connections between the two variables.

• scatter plot

• bar graph

• dot plot

• line graph

A graph that compares two categories within a data set. The whole bar represents all the data within one category. Then, each bar is separated into parts (segments) that show the percentage of each part in the second category.

• segmented bar graph

• bar graph

• scatter plot

• line graph

A relationship between two quantities where one tends to decrease as the other increases.

• negative association

• positive association

• no association

• correlation

A relationship between two quantities where one tends to increase as the other increases.

• positive association

• negative association

• no association

• correlation

How can you compare two data sets using pie charts?

• Use a bar chart instead of a pie chart for comparison

• Combine the data sets into one pie chart and compare the slices

• Use a line graph to compare the data sets

• Create separate pie charts for each data set and compare the sizes of the slices visually.
