Statistics [Foundation]
In this course on Statistics, we cover measures of central tendency for grouped and ungrouped data. We also calculate measures of dispersion, such as quartiles and the five-number summary, to plot box-and-whisker diagrams and use these statistical measures to analyse data and draw conclusions.
