Question

Mean of a set of observations is the value which:

• A. occurs most frequently
• B. divides observations into two equal parts
• C. is the sum of the observations
• D. is a representative of the whole group

Answer 1

The correct option is D is a representative of the whole group

We know, the value which occurs most frequently is the mode,
the value which divides the observations into two equal parts is the median
and the sum of observations is the total sum.
Thus, mean is the value which is representative of all the values as it is the average of all the values present in the series.

That is, Mean of a set of observations is the value which is a representative of the whole group.

Hence, option $D$ is correct.
