Answer:

range = 20

mean = 42.13333333

median = 42

mode = 42

Step-by-step explanation:

first let us arrange it in ascending order to avoid confusion.

Given:

31,32,35,37,38,40,42,42,42,46,47,47,50,51,52

range = Highest value - lowest value

range =51-31

mean =Σx/n

mean= ( 42+47+32+35+ 42+50+37+40+52+31+46+ 47+42+38+ 51 )/15

= 42.13333333

median = centre value

=42

mode= most repeating value

=42 (repeat three times)

Answer:

RANGE:-

RANGE = MAXIMUM VALUE - MINIMUM VALUE

52 - 31

= 21

Mean:-

Mean = Sum of all observations

Number of observations

MEAN = (42+47+32+35+42+50+37+40+52+31+46+ 47+42+38+51)

15= 42.23

Median:-

n = 15 (odd)

Median = (n + 1)th term = (15+1) th term= (16) th

2। 2 2

term = 8 th term = 40

Mode:-

Mode = 42(maximum frequency in 3 times)

Hope it will help
