An investigator wanted to see if there is a relationship between an individual's self-reported anxiety level and their accuracy of eyewitness recall. They showed 25 participants a video of a minor road traffic collision. Afterward, participants rated their anxiety on a scale of 1 (very calm) to 10 (highly anxious) and completed a recall test consisting of 20 specific details about the event.
When writing up the investigation, the researcher represented their data on a scattergram.
