Comparing Statistical Diagrams Flashcards

All 4 cards in this deck

Which statistical diagram should you use for data recorded over a period of time?

A time series graph (line graph), with time on the horizontal axis.

Which diagram is most appropriate for showing what proportion of a whole each category makes up?

A pie chart.

When comparing two data sets shown in statistical diagrams, what two things should your comparison mention?

An average (e.g. median or modal class) and the spread — with at least one comparison in context.

True or false? A dual bar chart is better than two separate pie charts for comparing the actual frequencies of two data sets.

True. Pie charts only show proportions, so frequencies cannot be compared without the totals.
