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.
