Question

find the mean,median and the mode of the following 7,7,2,5,7,3,4,1,7,8,4,5​

Answer 1

Answer:

Step-by-step explanation:

Mean = Sum of observations / No of observations

      =  (7+7+2+5+7+3+4+1+7+8+4+5)  / 12 = 60 / 12 = 5

Mean = 5

ascending order : 1,2,3,4,4,5, 5,7,7,7,7, 8

Median = ( n+1)th / 2 term = ( 12+1)th / 2 term = 13th / 2 term = 6.5th term

6.5 lies between 6 and 7 so

(6th term + 7th term) / 2 = (5+5) / 2 = 10/2 = 5

Median = 5

Mode = The number have highest frequency or highest  times a number repeats =  7 repeats 4 times which is highest

Mode = 7
