Students use frequency graphs to identify a range of measures and make sense of this data in a real-world context.
Students understand that a large number of data points allow a frequency graph to be approximated by a continuous distribution
This lesson unit is intended to help you assess how well students are able to interpret data using frequency graphs and box plots. In particular this unit aims to identify and help students who have difficulty figuring out the data points and spread of data from frequency graphs and box plots
This lesson unit is intended to help you assess how well students are able to:
•Interpret data and evaluate statistical summaries.
•Critique someone else’s interpretations of data and evaluations of statistical summaries.
The lesson also introduces students to the dangers of misapplying simple statistics in real-world contexts, and illustrates some of the common abuses of statistics and charts found in the media.
This lesson unit is intended to help you assess how well students understand the notion of correlation. In particular this unit aims to identify and help students who have difficulty in:
•Understanding correlation as the degree of fit between two variables.
•Making a mathematical model of a situation.
•Testing and improving the model.
•Communicating their reasoning clearly.
•Evaluating alternative models of the situation.
