2. You must add 1/2 to both side of the equation, then:
3. Now, you must multiply each side of the equation given by 10, therefore, you obtain the following result:
The mean is calculated by adding all the data values together, and then dividing the sum by the number of data values.
12+10+11+13+14+10+12+13+14=109
109÷9≈12.1
<u>The mean of the data set is about 12.1.</u>
