Question

I need the answer to number 2.

Step 1

*Mean:*

The arithmetic mean (also called the average*) *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.

**Obtaining the Mean:**

The **mean **for the given data can be obtained by entering the formula **“=AVERAGE(A2:A13)” **in EXCEL software.

The EXCEL output is shown below:

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 observations in the (*n*/2)th position and the (*n*/2 + 1)th position.

The median of ...
