Question

13. Find the mean, median, mode of: 12, 24, 24, 12, 30, 12

Answer 1

Step-by-step explanation:

∴ 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 = 18

∴ Median = 18
