Stage 5

Data analysis A
Examine standard deviation as a measure of spread
  • Identify standard deviation as a measure of spread

  • Calculate the standard deviation of a small dataset using digital tools

  • Compare small datasets using standard deviation

Determine quartiles and interquartile range
  • Determine the 5-number summary for sets of numerical data

  • Determine the 5-number summary from graphical representations

  • Determine the interquartile range (IQR) for datasets

  • Compare and explain the relative merits of range and IQR as measures of spread

Represent datasets using box plots and use them to compare datasets
  • Represent numerical datasets using a box plot to display the median, upper and lower quartiles, and maximum and minimum values

  • Compare 2 or more numerical datasets using parallel box plots drawn on the same scale

  • Compare and contrast the centres, spreads and shapes of 2 or more numerical datasets, using box plots and numerical statistics, including the 5-number summary

  • Determine quartiles from datasets displayed in histograms and dot plots, and represent these as a box plot

  • Identify and describe skewness or symmetry of datasets displayed in histograms, dot plots and box plots

  • Interpret box plots to draw conclusions and make inferences about the dataset
