Question

Find the mean for the given set of data 18,15,22,18,25,19,23

Answer 1

Mean = Sum of the all observation / Total no. of observation

Mean= 18+15+22+18+25+19+23/7
= 140/7
=20

Answer 2

Answer:

Mean=20

Step-by-step explanation:

The set of data is given as:

18,15,22,18,25,19,23

Mean for the given set of data is given as: $\frac{Sum of all the observations of the set}{total number of observations of the set}$

=$\frac{18+15+22+18+25+19+23}{7}$

=$\frac{140}{7}$

=$20$

Thus, mean of the given set of data is 20
