MULTIPLE CHOICE - Statistics

When would what graphs be appropriate to use?

Line graph

X-Y plot/ scatter plot

Tables

Bar graph

Double bar graphs

Broken-line graph

Circle graph

Line graph:

• used to track changes over short and long periods of time

  Scatter plot:

• Determine relationships between the two different things

• Tables:

• Data scores in rows and columns

  Bar graph:

• Compare things between different groups to track changes over time

  Broken line graph

  • shows how something varies over time

    Circle graph

    • trying to compare parts of a whole

    • Do not show changes over time
