Question

An experiment was conducted to investigate the effect of management training on the decision-making abilities of supervisors in a large corporation. Sixteen supervisors were selected and eight were randomly chosen to receive managerial training. Four trained and four untrained supervisors were then randomly selected to function in a situation in which a standard problem arose. The other eight supervisors were presented with an emergency situation in which standard procedures could not be used. The response was a management behavior rating for each supervisor as assessed by a rating scheme devised by the experimenter.a. What are the experimental units in this experiment?b. What are the two factors considered in the experiment?c. What are the levels of each factor?d. How many treatments are there in the experiment?e. What type of experimental design has been used?

Answer 1

A) 16 supervisors that were selected.

B) Training and Situation

C) - Trained and untrained

- Standard and Nonstandard

D) 4 treatments

E) Completely randomized block design experiment.

Explanation:

A) The experimental units are the subjects upon which the experiment was performed. In this case, that is the 16 supervisors that were selected.

B) The two factors considered were:

- The managerial training

- The situation in which a standard problem arose and also the emergency situation in which standard procedures could not be used.

C) The levels would be the values the experimenter observes as a result of the training and situation.

Thus, the levels are:

- Trained and untrained

- Standard and Nonstandard

D) Number of treatments are the total number of levels gotten in C above.

Thus, number of treatments = 4

E) Since the 16 supervisors that were selected were randomly assigned treatments, we can say it is a completely randomized block design experiment.
