Lesson 1
Review of Probability
Find simple probabilities as favourable ÷ total, and use the complement.
Lesson 2
Using Arrays for Two-Step Experiments
Use arrays to list the sample space of two-step experiments and find probabilities.
Lesson 3
Using Tree Diagrams
Use tree diagrams for multi-step experiments, multiplying along branches.
Lesson 4
Using Relative Frequencies to Estimate Probabilities
Estimate probabilities from data using relative frequency, and find expected numbers.
Lesson 5
Mean, Median and Mode
Find the mean, median and mode of a data set, and the range.
Lesson 6
Interpreting Data from Tables and Graphs
Read and interpret information from frequency tables, column graphs, line graphs and sector graphs.
Lesson 7
Stem-and-Leaf Plots
Read stem-and-leaf plots and find the median, mode and range from them.
Lesson 8
Grouping Data into Classes
Group data into class intervals, find the modal class and estimate the mean.
Lesson 9
Measures of Spread: Range and Interquartile Range
Find the range and the interquartile range (IQR) as measures of spread.
Lesson 10
Box Plots
Read a five-number summary and box plot, and find the IQR and range.
