Answer 1

Find the mean and median of the following data sets i) 3, 2, 7, 0, 9, 5, 6, 4, 8

Answer 2

a) Mean= sum of numbers / Total no. of observations

=> Mean =

$\frac{3 + 2 + 7 + 0 + 9 + 5 + 6 + 4 + 8}{9} \\ \\ \frac{44}{9} \\ \\ 4.9$

b) Arrange all numbers in ascending order ,

$0, \: 2, \: 3, \: 4, \: 5, \: 6, \: 7, \: 8, \: 9 \:$

=> Median = 5 ( median is the middle observation )
