Question

score of matches held in past 11 years is given as follows - 14,16,12,13,14,16,13,10,14,18,16 find the medium, mode, mean and range ​

Answer 1

Given :  score of matches held in past 11 years   , 14,16,12,13,14,16,13,10,14,18,16  ,

To find : the medium, mode, mean and range ​

Solution:

arrange the score in ascending order

10 , 12 ,  13 , 13 , 14 , 14 , 14 , 16 , 16 , 16 , 18

Total 11 Data points

Range = 18 - 10 = 8

Median = 6th data point    14  

14 & 16 repeated  maximum 3 times

Hence Dual Mode

14 , 16

Mean = (10 +12 + 13 + 13 + 14 + 14 + 14 + 16 + 16 + 16 +18 )/11  = 156/11

= 14.18

Mean = 14.18

Median = 14

Mode = 14 , 16

Range = 8

Answer 2

Answer:

Mean=14.18

Median=14

Mode=14,16

Range=8

Step-by-step explanation:

To find :- Range, Mode, Median, Mean

Range=Arrange the score in ascending order

10,12,13,13,14,14,14,16,16,16,18

total 11 data points

range = highest term - lowest term

18-10=8

range = 8

Median=(n+1/2)th

(11+1/2)th

(12/2)th

6th observation is 14

so,median =14

Mode=14&16 repeated 3 times

hence dual mode

mode=14&16

Mean=no of observation/total no of observation

10+12+13+13+14+14+14+16+16+16+18/11

156/11

mean=14.18
