Basic Statistics Problems Tutor


Introduction to Basic Statistics Problems Tutor

Statistics is the proper science of making effective use of numerical data connecting to groups of individuals or experiments. It deals by means of all aspects of this, counting not only the collection, analysis and interpretation of such information, except the planning of the gathering of data, in terms of the design of surveys and experiments. Now we will study the basic problems given by tutor. Let us see about the basic statistics problems.


Basic Statistics Example Problems Tutor


The following examples problems are used to learn statistics basic. It is the examples are given by the tutor.

Example 1

Find out the mean, median, mode, range of the following given numbers in statistics?

4,8,12,16,19,22,27.

Solution

The given numbers are 4,8,12,16,19,22,27.

Mean

Mean is the average of the given number. First find the total value of the given numbers.

Sum of the given numbers are = 4+8+12+16+19+22+27.

= 108.

The total value is divided by 7 (7 is the total given numbers) = 108/ 7

= 15.4

Median

Middle element of the given series is known as median.

The number series is 4,8,12,16,19,22,27.

The middle element of the above series is 16.

So the value of median is 16.

Mode

Mode is a copy value of the given series. Here no copy value.

Therefore the mode value is empty.

Range

Range is the subtraction of the values form least to high of the given number series.

Range = 27-4

= 23.


Example 2


Solve the mean, median, range of the following in basic statistics?

12,17,19,24,29.

Solution

The given numbers are 12,17,19,24,29.

Mean

Mean is the average of the given number. Find the total value of the given numbers.

Sum of the given numbers are = 12+17+19+24+29

=101.

Total values are divided by 5 (Here 5 is the total given numbers) = 101/5

= 20.2.

Median

Middle element of the given series is known as median.

The number series is 12,17,19,24,29.

The middle element of the above series is 19.

So the median value is 19.

Range

Subtract the minimum value from the topmost value of the series.

Range =29-12

=17.

These examples are the basic statistics problems given by tutor.
