Do the results make sense?
O A. It makes sense that the measures of variation cannot be calculated because there is not a large enough sample size to calculate the measures
variation.
O B. The measures of variation do not make sense because the standard deviation cannot be greater than the variance.
O C. The measures of variation make sense because the data is numeric, so the spread between the values is meaningful.
