A manufacturer of chisels is interested in determining how the angle at which the cutting edge is sharpened affects tool abrasion. To answer this question, engineers obtain 20 similar chisels. They sharpen five chisels at each of 22.5, 25, 27.5, and 30 degrees. Then, they measure the amount of abrasion (rated on a scale of 1 to 10, with 10 being the worst) after cutting several mortises (square holes) in 3/4-inch hard maple boards.
Identify the response variable in the given study.
A.
Mortises
B.
Amount of abrasion
C.
Cutting edge
Answer: B.
Amount of abrasion
