Question

find mean, median and mode of 12,24,24,12,30 and 12​

Answer 1

Answer:

∴ Mean = (12 + 24 + 24 + 12 + 30 + 12)/6

= 114/6 = 19

Numbers are 12, 24, 24, 12, 30 and 12

Mostly repeated term = 12

∴ Mode = 12

Now, arranging the numbers in ascending order = 12, 12, 12, 24, 24, 30

Here, number of terms 6 which is even

∴ Median = 1/2 {n/2 th term + (n/2 + 1) th term}

= 1/2 {6/2 th term + (6/2 + 1) th term}

= 1/2 {3th term + 4th term}

= 1/2 {12 + 24} = (1/2) × 36 = 1

∴ Median = 18

Answer 2

mean = (12+24+24+12+30+12)/6

= 114/6=19

Numbers are 12 , 24,24, 12 , 30 , 12

mostly repeated term 12

mode = 12

now , arranging the numbers in ascending.

order 12 , 12 , 12 , 24 , 24 , 30

here number of terms 6 which is even

median = 1/2(n/2th term +(n/2+1 th term )

1/2 ( 6/2 th term +( 6/2 + 1 th term )

1/2 ( 3 th term +4 th term )

1/2 = (12+24 ) = 1/2 ×36= 18

median = 18 .
