Given:

The frequency distribution table.

To find:

The mean average score on a test.

Solution:

The frequency distribution table is

$Marks (x_i)$ $Frequency(f_i)$ $f_ix_i$

x a xa

y b yb

z c zc

Sum a+b+c xa+yb+zc

Now, the mean average score on the test is

$Mean=\dfrac{\sum f_ix_i}{\sum f_i}$

$Mean=\dfrac{xa+yb+zc}{a+b+c}$

Therefore, the mean average score on the test is $\dfrac{xa+yb+zc}{a+b+c}$ .
