MEDIAN - Descriptive Statistics using Microsoft Excel Statistical Functions - Measures of Central Tendency

The practice sheet can be downloaded from Link. Statistics Marks Data - Download Sheet

About the Data Sheet - The data in this sheet is related to marks scored by 100 Students in a Statistical Test. 


Based on the data, we will use Microsoft Excel Statistical functions to analyse the descriptive statistics. 

In the Data Sheet, we have Data from A2:A101, A1 being the header of the Data. 

MEDIAN

In a numerical data set, the median is the point at which there are an equal number of data points whose values lie above and below the median value.

The MEDIAN Function in Excel returns the median of the given numbers. The median is the number in the middle of a set of numbers.

=MEDIAN(number1,number2,...)

In case of an even number of numbers in the set, then MEDIAN calculates the average of the two numbers in the middle.

In the Data Sheet, we have Data from A2:A101, A1 being the header of the Data. 

=MEDIAN(A2:A101)
Result is 75

Median in this context is that half of the students scored above 75 marks and other half of the students scored below 75 marks.
