Question
Students at Hunter College studied bicycle safety in New York City (Tuckel & Milczarski, 2014). They reported data on cyclists who were riding their own bikes and were not cycling as part of their job (they were not, for example, riding as delivery workers). They reported that 28.4% of male cyclists stopped completely at a red light, whereas 38.3% of female cyclists did so. 30.9% of male cyclists and 35.4% of female cyclists paused but then rolled through the red light. And 40.7% of male cyclists and 26.3% of female cyclists just ran the light.
What hypothesis test would the researchers conduct?
Explain your answer.
Explanation / Answer
Since variables gender and whether they stopped completely at a red light are categorical variables and we want to test whether they stopped completely at a red light is independent of gender, we must conduct Chi square test for independence.
