Question

Calculate Mean, Median, Mode, Lower and Upper Quartile. Also discuss the empirical relationships between quartile and percentile. Also calculate standard deviation for the data. 24 28 20 23 23 25 35 27 28 30 34 35 45 36 40 44 55 60 65 45 47 50​

Answer 1

the solution is

ascending order =20,23,23,24,25,27,28,28,30,34,35,36,40,44,45,45,47,50,55,60,65

mean=sum of observation//no. of observation

819/22=37.227

median =22(even)

n/2th term +n/2+1

2

22/2+22/2+1

11+11+1

23/2

11.5th term

35

mode=23,28,45
