Mean for the population data: µ=∑x/ N

Mean for the sample data: x?=∑x/ n

53 32 61 53 39 44 57

Find the mean, median, and mode age of these employees.

µ=∑x/ N

= (53+32+61+53+39+44+57)/7

= 339/ 7

=48.43

First step is to find the

32, 39, 44, 53, 53, 57, 61

The population size is seven which is an odd number so the middle value will be the median.

32, 39, 44, 53, 53, 57, 61

So Median= 53

We can observe that here 53 has occur two times and all other value have occur only one time, So the maximum frequency of this data is two and the corresponding value of this frequency is 53.

Hence Mode=53

10 5 19 8 3

We can find Mean, Median and Mode of this data set.
