Central Tendency is a measure that tell us where the middle of a bunch of data lies.
Mode: Mode is the most frequent measure or the measure that appears most.
Example 1:
1,3,5,6, 1,4
The mode of the distribution is 1 because it appears most often.
Median: Median is the middle measure.
Example 2:
1, 2, 3, 5, 6, 8, 9, 7, 10
The numbers are arranged in ascending order.
From the smallest number to the biggest number
1,2,3,5, 6, 7, 8, 9, 10
The median is 6 because it appears in the middle of the list.
Range: Range is the difference between the highest score or measure and the lowest score or measure.
Example 3:
10, 7, 8, 6, 2,8
The largest scores 10 and the smallest score is ‘2’.
The range is 10-2=8.
Mean: The mean is the same as the average. It is calculated by dividing the sum of all the scores by the number of scores that appear.
Example 4
1, 2, 3, 4, 10
All the numbers are added together
20÷5=4
The sum is divided by the number of scores in the list, so ‘4’ is the average.
