"A new study says X is good for you" is reported one week, and then the next week, a new study says "X is actually not so good for you!" Which is true?

In this course, we'll critique the experimental design (i.e. how did the investigators gather data? Was it a fair test with controlled variables? Does the correlation imply causation?) of some surveys and scientific studies reported by the media (and spend a bit of time determining whether the actual conclusions were distorted or cherry picked in the news). We'll then use the statistical enquiry cycle to plan our own investigations, gather and analyse data, and form conclusions.

Contexts: Surveys in popular culture

Essential vocabulary: bias, variables, controlled variables, independent variable, dependent variable, correlation, causation, mean, median, quartiles, box and whisker plots
