Recreational running has taken off in recent years as a popular fitness activity. Identifying the best shoes for running has been the subject of much debate and different studies have shown different benefits to different types of shoes from barefoot running to stability shoes with large amounts of cushioning. Researchers wanted to compare knee load (a continuous measure with higher numbers indicating greater knee load) between four types of shoe types, barefoot (no shoes), minimal, neutral, and stability. Higher values of knee load may be associated with greater injury risk. A total of 200 runners of similar height and weight were included in a study and were classified by their choice of running shoe (TYPE_NEW) and measured knee load (LOAD) on a typical run. Using a 0.05 significance level, we need to determine if there is a difference in average knee load between shoe types. To do so, answer each of the following questions.

What type of analysis is most appropriate here?

A. Simple Linear regression

B. Multiple Linear regression

C. One-Way ANOVA

D. ANCOVA

E. Logistic regression
