Question

8. Find the mean, mode, median and range of the following data:
7, 7, 24, 5, 2.
One number is added to this data. What could that number be if
(a) the mode remains the same?
(b) the median remains the same?
(c) the mean remains the same?
(d) the mean is increased by 2?​

Answer 1

Mean = 9

Median = 7

Mode = 7

a) If the mode remains same then the number would be any other than 24, 5 & 2

b) If the median remains same then the number would be greater than 7

c) If the mean remains same then the number would be 9

d) If the mean is increased by 2 then the number would be 21
