The mean of a data is defined as _________. Fill in the blanks to make the statement true.

Solution:

Given, the mean of a data is defined as _________.

We have to fill in the blanks to make the statement true.

The mean is the average or a calculated central value of a set of numbers and is used to measure the central tendency of the data.

Central tendency is the statistical measure that recognizes the entire set of data or distribution through a single value.

It provides an exact description of the whole data.

Mean = sum of all observations / number of observations

Example: consider the data 2, 4, 6, 8

Sum of observations = 2+4+6+8

= 20

Number of observations = 5

Mean = 20/5

= 4

Therefore, the mean of a data is the sum of all observations divided by a number of observations.
