Year 7 - Statistics & Probability

Standard 7.SP.1.2 - Practice calculating the mean of a sample.

Included Skills:

Data representation and interpretation
• Identify and investigate issues involving numerical data collected from primary and secondary sources
- obtaining secondary data from newspapers, the Internet and the Australian Bureau of Statistics
- investigating secondary data relating to the distribution and use of non-renewable resources around the world
• Construct and compare a range of data displays including stem-and-leaf plots and dot plots
- understanding that some data representations are more appropriate than others for particular data sets, and answering questions about those data sets
- using ordered stem-and-leaf plots to record and display numerical data collected in a class investigation, such as constructing a class plot of height in centimetres on a shared stem-and-leaf plot for which the stems 12, 13, 14, 15, 16 and 17 have been produced
• Calculate mean, median, mode and range for sets of data. Interpret these statistics in the context of data
- understanding that summarising data by calculating measures of centre and spread can help make sense of the data
• Describe and interpret data displays using median, mean and range
- using mean and median to compare data sets and explaining how outliers may affect the comparison
- locating mean, median and range on graphs and connecting them to real life
