A teacher wants to compare how two classes have performed on a test they have taken. should the teacher report the test mean or the test median? which measure might describe the data set better? why?

For given situation, the Median measure might describe the data set better.

We know that, the median is the middle number in a sorted, ascending or descending list of numbers.

Also, it can be more descriptive of that data set than the mean.

The median is used because:

It is the most informative measure of central tendency for skewed distributions or distributions with outliers.

For example, the median is often used as a measure of central tendency for income distributions, which are generally highly skewed.

The median is calculated by taking the “middle” value, the value for which half of the observations are larger and half are smaller.

When there is a possibility of extreme values, the median is generally the better measure to use.

Therefore, for given situation, the teacher should report median.

The Median measure might describe the data set better.
