Question

find the mode and median of given data. 1)17,18,21,34,21,16,9,21,18,36,32. 2)32,41,28,54,35,26,23,33,38,40.

Answer 1

1) 21 is the mode
median is
arrange the given date in ascending oder
9,16,17,18,18,21,21,21,32,32,36

formula for median =n+1/2
therefore n =11.( n =observation)
11+1=12
12/2=6
therefore 6th observation is the median
so 21 is the median of the data

2) no mode

median is
arrange the data in ascending order
23,26,28,32,33,35,38,40,41,54
therefore 6th one is the median
so 35 is the median
