Explanation:

Answer 2

Mean=how many terms or values in the setsum of all terms

Add the numbers in the example data set:

20+24+25+36+25+22+23=17520+24+25+36+25+22+23=175

Divide by the number of data points in the set. This set has seven values so divide by 7.

Insert the values into the formula to calculate the mean. The mean equals the sum of the values (175) divided by the number of data points (7). Since

\frac{175}{7}=257175=25

the mean of this data set equals 25. Not all mean values will equal a whole number.
