Compare Data Sets

Compare your estimates for 50-second intervals to your estimates for 20-second intervals. Use your data set from the third trial for the 50-second intervals and your data set from the third trial for the 20-second intervals. Do not use graphs to make your comparison. Think about the following questions:

  • What tools can you use to analyze the data?
  • What evidence can you use to justify your conclusion?
  • What is the range for each data set?
  • How can you compare the data sets?
  • How can you compare the measures of center and spread for the two sets of data?
  • How can you compare two data sets when the numbers in each data set are based on different times—that is, 20 seconds versus 50 seconds?
