Question

Find the mean of the following data 9, 7, 11, 13, 2, 4, 5, 5

Answer 1

Answer:

7

Step-by-step explanation:

By arranging the given data in ascending order,

2,4,5,5,7,9,11,13

By using the mean formula

m=sum of the terms/number of terms

m=2+4+5+5+7+9+11+13/8

m=56/8

m=7

Therefore the mean of the given data is 7.

Answer 2

The mean value is 7.

Given,

The numbers 9, 7, 11, 13, 2, 4, 5, 5.

To Find,

The mean of the given numbers.

Solution,

Here, a set of numbers are given they are,

9, 7, 11, 13, 2, 4, 5, 5.

And a total of eight numbers are there.

The mean of a given set of numbers is the average of those numbers.

The average or the mean can be calculated as,

First, need to find out the total of the numbers,

9 + 7 + 11 + 13 + 2 + 4 + 5 + 5 = 56.

So, the total is 56.

And there are 8 numbers in the given sequence.

So, the mean  = $\frac{total}{number of elements}$

mean = $\frac{56}{8}$

mean = 7.

Hence, 7 is the mean value of the given set of numbers.
