Answer 1

Explanation:

The value obtained by dividing the sum of all the values in a data series, by the number of values is

(a) Median

(b) Mode

(c) Arithmetic Mean

(d) None of these

Answer 2

The right response to the provided question is option c: Arithmetic mean.

• The option given in the questions is the different types of mathematical tools for computing central tendency.
• Arithmetic mean is also called the average of a given value or the values under consideration.
• It can be found by firstly adding all the given data or the numbers. Then the sum of these data or the numbers is divided by the number of values that were added.
• It can be expressed as:

=> Arithmetic mean= $\frac{Sum or addition of all observations}{Number of observations under consideartion}$

• Median is incorrect because it is the central most valuable from all the observations.
• While the mode is the observation that can be calculated by counting the most frequent observation from all observations.
• Hence, option c is the correct answer.
