MEASURE OF CENTRAL TENDENCY|| CLASS 1||JKPSI/JKSSB SSC || BASIC TO ADVANCE MATHS BY RUKHSAR SIR

Measure of Central Tendency is a key concept in statistics used to describe the center or typical value of a data set. These measures help in summarizing a large set of data into a single value, making it easier to understand and analyze. Types of Central Tendency: Mean: The average of all data points. It is calculated by adding all the values and dividing by the total number of values. Formula: Mean=∑XN\text{Mean} = \frac{\sum X}{N} Where ∑X\sum X is the sum of all data points, and NN is the number of data points. Median: The middle value when the data set is arranged in ascending or descending order. If there’s an even number of data points, the median is the average of the two middle numbers. Mode: The value that occurs most frequently in a data set. A data set can have one mode, more than one mode, or no mode at all. Variance: Measures how far each data point is from the mean. It is calculated by averaging the squared differences from the mean. Formula: Variance=∑(X−Mean)2N\text{Variance} = \frac{\sum (X - \text{Mean})^2}{N} Standard Deviation: The square root of variance. It gives a measure of the spread or dispersion of data points around the mean. Formula: Standard Deviation=Variance\text{Standard Deviation} = \sqrt{\text{Variance}} Deviation: The difference between each data point and the mean of the data set. It shows how much a particular value deviates from the central tendency. #JKPSIMaths #JKSSB #CentralTendency #JKPSI #JKSSBSSC #JKPSIfreeclasses #JKPSIpreviousyearquestions #JKPMaths #Mean #Median #Mode #StandardDeviation #Statistics #NaibTehsildar #Variance #Deviation #RukhsarSir #MathsStrategy #BasicToAdvanceMaths Central Tendency, JKPSI, JKSSB, Statistics, Mean, Mode, Median, Variance, Standard Deviation, Deviation, SSC Maths, Naib Tehsildar, Maths Strategy, Previous Year Questions, Free Classes, Basic to Advanced Maths.
