Online tutors are the people who will help the students in studies and explain the new extra skills by using a step-by-step process. Online tutors are explaining the problems to the students. So the students can clear the doubts within a minute. Statistics is the most important concept in maths. Statistics is the appropriate science. Now we will see the free statistics examples. These examples are given by online tutor.

**Example 1**

**What is the mean of the following sequence in statistics?**

**27,34,48,57,69.**

**Solution**

The given numbers are 27,34,48,57,69.

**Mean**

We can find the mean with the help of average.

Mean = `(27+34+48+57+69)/(5)`

= `(235)/(5)`

= 47.

Solution is 47.

**Example 2**

**Find out the Median for the following sequence. 45,48,53,58,67.**

**Solution**

First sort the above numbers. We get 45,48,53,58,67.

The center element is 53.

Therefore median=53.

**Example 3**

**What is the mean, median, mode and range of the below order in statistics?**

**26,37,49,57,63,69,78.**

**Solution**

The given numbers are 26,37,49,57,63,69,78.

**Mean**

Mean is the average of the given number. Calculate average with the help of total value of the given sequence.

Sum of the given numbers are = 26+37+49+57+63+69+78

= 379.

Total values are divided by 7 (7 is the total numbers) = `(379)/(7)`

= 54.1.

**Median**

Center element of the given series is a median.

The number series is 26,37,49,57,63,69,78.

The center element of the above sequence is 57.

So the median = 57.

**Mode**

Mode is the duplication of the series. The given sequence no duplicates value. Therefore the mode is empty.

**Range**

Less the low value from the high value of the series.

Range =78-26

=52.

**Homework problem 1**

Find the median value for the following series.56,58,63,68,72.

**Answer:**

The middle element is 63.

Therefore median =63.

**Homework problem 2**

Find the mode value for the following.45,48,58,72,80,72.

**Answer:**

Mode =72.
