The image of mean is represented below. To calculate mean, two essential parameters are needed and these parameters are Set of data and Corresponding frequencies accordingly.
The formula for calculating mean:
Mean = ∑fx / ∑f
Where;
∑fx = Summation of the product of the data and its corresponding frequency.
∑f = Summation of the frequencies
Let’s solve an example;
Find the mean when the set of data is 12 and the corresponding frequencies accordingly is 2.
This implies that;
| x | f | (fx) | fx |
|---|---|---|---|
| 12 | 2 | (12 x 2) | 24 |
∑fx = 24
∑f = 2
That is, Mean = ∑fx / ∑f
Mean = 24 / 2
Mean = 12
Therefore, the mean is 12.
