Question

find the mean of the data :4;4;5;7;6;7;7;12;

Answer 1

Answer:

6.5

Step-by-step explanation:

4, 4, 5, 7, 6, 7, 7, 12

Sum of observations = 4 + 4 + 5 + 7 + 6 + 7 + 7 + 12 = 52

Number of observations = 8

We know that ;

Mean = $\bf{\frac{Sum\:of\:observations}{Number\:of\:observations}}$

Mean = $\frac{52}{8}$

Mean = 6.5

Hence, the mean of the data is 6.5
