Description
The relationships between students in Year 7 can be determined using statistical measures. In this unit students will survey a sample of their peers, calculate and identify a range of statistical measures and analyse the results to justify their opinion on what is a typical year 7 student. In the context of identities and relationships the students will represent similarities and differences in the Year 7 cohort using a range of measurements, charts and calculations.
Learning Outcomes
Plan and conduct investigations using the statistical inquiry cycle as outlined below:
determine appropriate variables and data collection methods;
gather, sort and display multivariate category, measurement and time-series data to detect patterns, variations, relationships and trends;
compare distributions visually;
communicate findings using appropriate displays
Create tally charts, bar charts, line graphs and pie graphs
Work with scale to draw graphs
Calculate the range and mean of discrete data
Identify the median and mode of a set of discrete data
