Find the mean median and mode of the set of values Ageyears

Find the mean, median and mode of the set of values.

Age(years). 10. 11. 12. 13. 14. 15. 16

Frequency. 6. 9. 13. 16. 10. 5. 4

1. The mean is approximately ? Years ( round to two decimal places)

2. Find the median. The median is ? Years

3. Find the mode-- the mode is ? Years or There is no mode

Solution

Mean = Average of all readings

Mode is the age which has maximum frequency

Median is 32nd entry i.e. between 12 and 13 hence 12+4/16

Mean = 12.73

Mode = 13

Median = 12.38
