Probability and Statistics | Lec-36 | Measures of Dispersion |Range, Quartiles, Interquartile Range

Welcome to Lecture 36 of the Probability and Statistics series on Unlock Mathematics!

In this lecture, we focus on important statistical measures that describe the spread of data, including:

Measures of Dispersion: Why they are important

Range: Understanding the simplest measure of spread

Quartiles and Interquartile Range (IQR): Dividing data into parts

Calculations for grouped and ungrouped data

Significance of dispersion in interpreting data variability

Detailed examples to strengthen understanding

Mastering these concepts will enhance your ability to summarize and interpret datasets effectively.
