This resource bundle contains 8 clear video tutorials that explain the main measures of central tendency in statistics. Each video takes students step by step through key concepts, using examples and applications that support classroom teaching and independent study.

The bundle covers both basic skills and more advanced statistical applications:

Finding the Mean of a Data Set I

Finding the Mean of a Data Set II

Finding the Median of a Data Set

Finding the Mode of a Data Set

Mean of a Probability Distribution

Sample Mean

The Mean and Normally Distributed Data

Weighted Mean

These videos can be used for whole-class teaching, homework support, or revision. They are particularly relevant for GCSE Mathematics (statistics strand) and for A-Level Mathematics/Statistics courses.

Learning outcomes
