Sagot :

Answer:

Step 1: Arrange the observations in ascending or descending order of magnitude.

Step 2: Determine the total number of observations, say, n.

Step 3: If n is odd then the median = value of (n+12)th observation.

Answer:

Step 1:

Arrange the observations in ascending or descending order of magnitude.

Step 2:

Determine the total number of observations, say, n.

Step 3:

If n is odd then the median = value of (n+12)th observation.

Example:

1. 12, 18, 18, 18, 18, 18, 11, 18, 18, 18, 18, 18, 12

Mean = 16.5

Median = 18

Mode = 18

2. -12, -23, 1, -26, -20, -19, 0, -10, -11, -23, -23, -24, -20, -9, -9

Mean = 15.2

Median = -19

Mode = -23

Hope This Helps :))
