About this course
This free course, Interpreting data: Boxplots and tables, is concerned with two main topics. In Section 1, you learn about graphical display, the boxplot. The other topic, covered in Sections 2 and 3, is that of dealing with data presented in tabular form.
- Understand and use the following terms: boxplots, box, whisker, upper and lower adjacent values, rate, time series, line plot.
- Demonstrate an awareness of the idea that the general pattern of a set of data, in terms of location, dispersion and skewness, can be graphically represented in a boxplot.
- Understand that boxplots can be used to provide a quick and simple comparison of data sets.
- Understand that patterns in tabular data can be made clearer by leaving out unhelpful information, by including extra pieces of useful information or by drawing appropriate graphs.
- Describe and compare data sets on the basis of boxplots.
