Learning goals
- We are learning to construct displays, including column graphs, dot plots and tables, appropriate for the type of data.
- We are learning to acquire data and construct displays including column graphs, dot plots and tables appropriate for the type of data, determining the highest frequency (mode) of the data set.
- We are learning to interpret and compare data displays, including side-by-side column graphs, tables and diagrams for two categories (e.g. age, height) and compare the usefulness of each display for data interpretation.
- We are learning to interpret and compare the four types of data sets (ordinal, nominal, discrete, continuous) using comparative displays and determining the range, mode (frequency) and shape of data in graphs, dot plots and bar charts.
