Find Mean, mode, range and median for given numbers.
The given numbers are,
In statistics, the mode is described as most repeated values.
In this given values 30 is repeated.
So, the mode is 30.
The range is defined as difference among smallest value and maximum value.
The given numbers are,
In this given numbers highest value is 64.
Then smallest value is 10.
So the range is,
= 64 – 10
Median means center values.
The given values are 30, 25,64,10,30.
Now sort the numbers in ascending orders.
So, the x median value is 30.
These are merits and demerits of statistics.
