08:30 – 10:15Turn a failure into teaching
You are studying how neighbourhoods cope with extreme heat. Overnight, a research assistant finds that several street sensors stopped recording on the hottest afternoons. Filling the gaps with an average would make the places of greatest interest look milder, so you postpone the planned analysis. Today’s class is about missing data. After removing private details and unpublished findings, you turn the problem into an exercise. Should the class exclude the incomplete results, estimate the gaps or narrow the research question? You show how each choice changes the conclusion the evidence can support.
