Choosing Appropriate Measures

Consider the distribution type of this graph, which Measure of Center would fit it best?

• Mean

• Median

If we are using the Median as the Measure of Center, which Measure of Variability should we use to best represent the data?

• IQR

• MAD

Which measure of variability should you use?

• IQR

• standard deviation

Given that the data is symmetric, which pair of measures should be used to represent the data?

• center: median

  spread: standard deviation

• center: mean

  spread: IQR

• center: mean

  spread: standard deviation

• center: median

  spread: IQR

Consider the distribution type of this graph, which Measure of Center would fit it best?

• Mean

• Median

Choose the appropriate measures to describe the center and spread of the distribution.

• median and interquartile range because the distribution is not symmetric.

• median and interquartile range because the distribution is symmetric.

• median and the outlier because the distribution is symmetric.

• median and the outlier because the distribution is not symmetric.

Isiah collects data from two different companies, each with four employees. The results of the study, based on each worker's age and salary, are listed in the tables above. Which statement is true about these data?

• The median salaries in both companies are greater than $37,000

• The mean salary in company 1 is greater than the mean salary in company 2

• The salary range in company 2 is greater than the salary range in company 1

• The mean age of workers at company 1 is greater than the mean age of workers at company 2

Determine whether the mean is less than, greater than, or equal to the median.

• The mean is greater than the median.

• The mean is less than the median.

• The mean is approximately equal to the median.

Determine whether the mean is less than, greater than, or equal to the median.

• The mean is less than the median.

• The mean is approximately equal to the median.

• The mean is greater than the median.
