It deals with not only the collection in all aspects,analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments. Now we will see the statistics problems.

Find out the median,mean, mode and the range of these numbers?
14,18,20,27,30.
Solution
The given numbers are 14,18,20,27,30.
Mean
The mean is the average of the given number. with the help of the total value of given numbers we can find the average.
Sum of the given numbers are = 14+18+20+27+30
=109.
Now divide the total value with 5 (5 is the given numbers total) =
= 21.8
Median
Median is the central value of the given number series.
Need help with median formula
The number series is 14,18,20,27,30.
The central value of the above series is 20.
Therefore we can say the median is 20.
Mode
Mode is a duplicate value of the given number series. Here no same value.
So the solution of mode is null or empty.You can avail Free math deal
Range
From the highest value subtract the least value in the series.
Range= 30-14
= 16.
