Find the mean of the following data:
$x$:19212325272931
$f$:13151618161513.


To do:

We have to find the mean of the given data.

Solution:

$x$$f$$f \times\ x$
1913247
2115315
2316368
2518450
2716432
2915435
3113403
Total1062650

We know that, Mean$=\frac{\sum fx}{\sum f}$ 

Therefore,

Mean $=\frac{2650}{106}$

$=25$

The mean of the given data is $25$.
