Question

Determine the mean, median, and mode for Determine the mean, median, and mode for the following data set, which shows the ages of all of the employees at your company: 18, 26, 27, 30, 25, 40, 32, 29, 31, 32the following data set, which shows the ages of all of the employees at your company: 18, 26, 27, 30, 25, 40, 32, 29, 31, 32

Answer 1

mean : we add the data, we divide by the number

(18+ 26+ 27+30+25+ 40+32+ 29+31+32)/10=251/10=25.1

mean age: 25.1 years

median :

The median of a statistical series is a number such that there are as many values

less than or equal to this number than values ​​greater than or equal to this

number.

Noticed :

- arranging the values ​​of the series in ascending order makes it possible to determine more

easily the value of the median.

- the median is not necessarily a value of the series.

18 25 26 27 29 30 31 32 32 40

10 data, even series

10/5 =5, to get the median we do the half-sum of the 5th and 6th values: (30+31)/2=30.5

median age: 30.5 years

mode :the most frequent value of a statistical series

mode :32
