Questions and Answers

1.
Directions:Match each term with the correct statement below. The terms may be used more than once. A researcher wanted to test whether the amount of noise in a widget factory affected how much work employees accomplished. Three groups of employees were tested. All three groups did the same type of work, were equally trained to do the work, were tested at the same time of the day, used the same equipment, etc. The number of widgets assembled by the employees in one hour was determined. Group one was given headphones that blocked out almost all outside noise. Group two was given earplugs that blocked out some, but not all of the outside noise. Group three was not given anything to block out noise.
