Question

Find the mean of the following data set. 42, 45, 58, 63 42 47 52

Answer 1

You have to add all the numbers and then with that sum divide it by the number of numbers. In this case it would be 42+45+58+63+42+47+52=349. Now divide that by the numbers of numbers which in this case is 7, ~49.85(answer).

Answer 2

The arithmetic mean of the given set of data { 42, 45, 58, 63 42 47 52 } rounded to the nearest tenth is 49.9.

What is Arithmetic mean?

Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.

Mean = Sum total of the number ÷ n

Where n is number of numbers

Given the sets;

• 42, 45, 58, 63 42 47 52
• n = 7

We add the numbers

42 + 45 + 58 + 63 + 42 + 47 + 52 = 349

Mean = 349 / 7

Mean = 49.9

Therefore, the arithmetic mean of the given set of data { 42, 45, 58, 63 42 47 52 } rounded to the nearest tenth is 49.9.
