# Let us find the m

Answer :

Arithmetic mean is just the average value of the data or variables given in the data.

To find the mean using direct method, let’s create a table showing frequencies and f_{i}x_{i}.

So, we have

∑f_{i}x_{i} = 750

∑f_{i} = 30

Using the direct method, we have the formula for arithmetic mean.

Using the above values, we get

⇒ Mean = 25

**Thus, mean is 25.**
