Asked Feb 8, 2019

What is the value of SS (sum of squared deviations) for the following population? Population: 2, 3, 0, 5


Expert Answer

Step 1

Obtain mean of the population.

The data points of the population are:

Population X: 2, 3, 0 and 5.


Mean is an important measure of center when the data is quantitative. Mean of a data set is the sum of the data set divided by the size of the data set.

The mean of the population is obtained as 2.5 from the calculation given below:

Step 2

Obtain the sum of squared deviations from mean for the given population.

The mean of the population is 2.5.

Sum of squared deviations:

The sum of squared deviations indicates by how much the data points in the dataset vary from the given number (generally mean).

The general formula for sum ...
