Lesson 1
Mean, Median, Mode and Range
Calculate mean, median, mode and range to describe the centre and spread of a data set.
Lesson 2
Comparing Data Displays
Compare two data sets using median, mean and range, and interpret differences in centre and spread.
Lesson 3
Stem-and-Leaf Plots
Read and construct ordered stem-and-leaf plots, find the median and range from ordered leaves, and compare two groups using a back-to-back display.
Lesson 4
Quartiles and Interquartile Range
Find Q1, Q2 and Q3 by splitting an ordered data set, calculate IQR = Q3 − Q1, and use it to compare the spread of two groups.
Lesson 5
Outliers and Data Interpretation
Identify outliers, explain how they affect the mean but not the median, and choose the appropriate measure of centre.
Lesson 6
Box Plots
Practise box plots with concise examples and mastery checks.
Lesson 7
Comparing Data with Box Plots
Practise comparing data with box plots with concise examples and mastery checks.
Lesson 8
Shape of Distributions
