The mean is less than the median, which is frequently less than the mode, if the data distribution is skewed to the left. The median = the mean if the data distribution is symmetric.

02

Content Explanation

The mean is calculated using the below formula:

Mean=∑fxN

Mean=10621Mean=5

Median=(21+12)Median=11thterm

Cumulative frequency lies in x=5

Therefore, mean is equal to median.
