The mean of this distribution is free from the influence of outlier(s). C. The mode of this distribution is 100. D. The median may be the most appropriate measure of central tendency for this distribution.

Explanation / Answer

The mean is the average of the numbers. To calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Average daily rainfall during the week: 0.99
Average daily rainfall during the weekend: 1.67

From the data, we can observe that there is an observable difference when it comes to the average rainfall during the weekdays in comparison to the average rainfall during weekends.
