How to Calculate and Solve for Number Average Molecular Weight | Polymer
Last Updated on December 5, 2022
The image of mean is represented below
To compute for 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
Mean = ∑fx / ∑f
Mean = 24 / 2
Mean = 12
Therefore, the mean is 12.
