Which MOCT is best to summarize the data in this graph?

• measure of central tendency

• mean

• median

Find the mean of the data set.

(a)  

If data is skewed right, then the mean will be...

• greater than the median

• less than the median

• equal to the median

Which of the following statements is correct?

• Approximately 50% of the data are above/below the mean

• Less than 50% of the data are above the mean

• More than 50% of the data are above the mean

• Less than 50% of the data are below the mean

The distribution of data is skewed right. What is the relationship between the mean and median?

• median > mean

• mean > median

• mean = median

• Impossible to tell.

• Mean

• Median

• Mode

• Range

Find the difference between the medians of version A and B.

(a)  

The given distribution is skewed left. Compare the median and the mean.

• The median and the mean are the same because they both are measures of center

• The median is less than the mean since the distribution is skewed left.

• The median is greater than the mean since the distribution is skewed left.

• There is not enough information to compare the median and the mean.
