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
