Key concepts, formulas, and definitions from Statistics for MHT-CET Mathematics preparation.
Key Topics to Revise
Introduction and Basic Concepts
- Statistics deals with data collection and analysis
- Measures of central tendency (mean, median, mode) show where data is centered
- Measures of dispersion show how data is scattered around the central value
Range and Coefficient of Range
- Range is the simplest measure of dispersion
- Range = Maximum value - Minimum value
- Coefficient of range provides relative comparison
Mean Deviation
- Mean deviation uses absolute values of deviations
- Can be calculated about mean, median, or mode
- Mean deviation about median is generally smaller
Variance and Standard Deviation - Core Concepts
- Variance is mean of squared deviations from mean
- Standard deviation is positive square root of variance
- Most important measures of dispersion for JEE Main
