Question

II. Find the mean, media and mode of each set of data.

1. 12, 12, 14, 16, 18, 20

2. 80, 83, 82, 85, 87, 93, 83, 85, 88, 80

3. 125, 100, 150, 125, 175

Answer 1

Answer:

1. Mean = 15.33

  Median = 15

  Mode = 12

2. Mean = 84.6

   Median = 84

   Mode = 80, 83, 85

3. Mean = 135

   Median = 125

   Mode = 125

Hope it helps:)

Answer 2

I. Mean = Sum of all observations / No. of observations

=> 12 + 12 + 14 + 16 + 18 + 20 / 6

=> 92 / 6

= 15.33333.....

= 15.3

Mode = 12

Because 12 is occurring most frequently.

Median

Step 1 => Arrange the values in ascending order.

Step 2 => Then the middle observation will be the median of the data.

Here we will get 2 numbers as the median but since it is not applicable we will use another method.

12, 12, 14, 16, 18, 20

Find average of 14 and 16

14 + 16 / 2

30 / 2 = 15

Therefore Median of the data is 15.
