Arithmetic Mean
The most common average, calculated by dividing the sum of all observations by the total number of observations.
Median
The middle value of a dataset when arranged in ascending or descending order, dividing the data into two equal halves.
Mode
The value that occurs most frequently in a given set of observations, representing the peak concentration of data.
Range
The simplest measure of dispersion, calculated as the difference between the highest and lowest values in a distribution.
Standard Deviation
The most reliable measure of dispersion that calculates the square root of the average of squared deviations from the mean.
Correlation
A statistical tool used to measure the direction and strength of the relationship between two economic variables.

Board Exam Info
In the Madhya Pradesh (MPBSE) Class 11 Economics board exams, this chapter typically carries around 8 to 12 marks. Common question types include direct numerical problems for calculating Mean, Median, Mode, or Standard Deviation, short-answer theoretical questions defining statistical tools, and occasionally matching or objective-type questions based on formulas and properties.
Frequently Asked Questions
Which average is best affected by extreme values?
The Arithmetic Mean is heavily affected by extreme values (outliers) because it takes every single observation into account during calculation.
Are numerical questions compulsory from this chapter in MPBSE exams?
Yes, numerical problems are very common and often compulsory or have internal choices, so practicing formula-based sums is essential.
What is the difference between dispersion and central tendency?
Central tendency gives the central or average value of a dataset, whereas dispersion measures how scattered or spread out the data points are around that central value.
