Expert Answer

Step 1

Mean:

The arithmetic mean (also called the mean) is the most commonly used measure of central tendency. It is calculated by summing up the observed numerical values of a variable in a set of data and then by dividing the total by the number of observations involved.

The formula for calculating the mean from a frequency table is given and calculated as follows:

Step 2

Median:

The median is the middle-most observation in an ordered (in an ascending or descending order) data set. For an odd number of observations, n in the data set, the median is the observation in the (n + 1)/2th position. For an even number of observations, n in the data set, the median is the observation in the average of the ob...
