Expert Solution
Step 1

For ordinal data mean cannot be found as it require an arithmetic operation like addition and division of all data values. So mean cannot be calculated.

The data is arranged in order and we have total of 12 data points, so the median will be the middle value which is nothing but the average of sixth and seventh data point. As this is ordinal data we cannot perform arithmetic operation. so median is also cannot be computed as there are even number of data points.
