This is a how-to-video which demonstrates techniques to find the median of number in a series. This demonstration takes the following example.
In this tutorial video the author shows how to find the length of the median of a trapezoid. He starts to show that we first need to add the sum of the parallel sides of the trapezoid which are on the either side of the median. Now this obtained value is to be divided by two to get the length of the median. He explains that the length of the median of a trapezoid is nothing but the average of the lengths of the parallel sides of the trapezoid. If you want to learn how to find the length of th...
This video shows us the method to find the median and the inter-quartile range. The first step involves the arrangement of the numbers in the ascending order. Median is the middle number. The middle number is the number at (number of numbers + 1)/2 if the number of numbers is odd or the (number of number)/2 if the number of numbers is even. In the example the number is located at [(11+1)/2] or the 6th number. The inter-quartile range is higher quartile - lower quartile. The higher quartile is...
Follow this video to learn how to formulate calculations in Microsoft Excel. First type in a list of numbers in the cells. In order to calculate the median click on the cell where you want the answer to be shown. Then type equals, average, open bracket and insert the cell code where the first number is, colon, and then type in the cell where the last number in the list lies, and close brackets. In practice this is an example where the numbers are in a list from cell A1 to cell A11: =AVEARAGE(...
The Mean is the average number, the Median is the center of the group and the Mode is the number that shows most often.
If you use Microsoft Office Excel on anything resembling a regular basis, odds are you work with numbers.

This video shows the method to find the variance and standard deviation using Excel. The variance shows the variability of the data points from the median. We find the difference of the median and the mean. We write the formula using '=' sign. The median and data points are put in it by selecting the appropriate cell. The median is made an absolute constant by pressing the F4 key. This is squared by using '^2'. This is multiplied to the frequency using '*'. The result is found for all the dat...
This is an interesting mathematical instructional video on how to make a quartile diagram. This example is about 34 grades obtained by chemistry class students. We need a minimum value, a maximum value, Q1, Q2 and Q3 values to make a quartile diagram. The minimum is 43 and the maximum is 92. To calculate Q2 median formula (n+1 over 2)is used. The Q2 median is 17.5. So the average of 69 and 71 is 70 and hence Q2 70. Similarly Q1 is calculated as 61 and Q3 is calculated as 79. Now you can draw ...
