Should I use average or median?
Both average and median measure the central tendency of the data Usually, we use the average statistic.
We prefer the median in one of the following cases:

2. The data is very skewed, and the sample size is not large
In these cases, one outlier or one rare extreme value might change the average dramatically.
The median is not affected by extreme values.
