We strongly recommend trying these Quick revision questions before your tutorial.

A study of obstructive sleep apnoea (OSA) in adults with Down Syndrome (de Carvalho et al. 2020) had \(n = 60\) adults undergo a sleep study. The data are shown in Fig. 3.1.

FIGURE 3.1: The obstructive sleep apnoea data set

What would be the appropriate graph to show the distribution of the age of the participants?
Bar chart Scatterplot Histogram Boxplot
What would be the appropriate graph to show the distribution of the gender of participants?
Bar chart Scatterplot Histogram Boxplot
What would be the appropriate graph to show the relationship between gender and REI?
Stacked bar chart Scatterplot Pie chart Boxplot

Age is quantitative, so histograms or stem-and-leaf plots are appropriate.
Gender is qualitative, so bar charts or pie charts are appropriate.
Gender is qualitative, and REI is quantitative, so a boxplot is appropriate.
