Question

A manufacturer of tile is experimenting with new material and wants to determine the optimal parameter settings for firing that will result in tiles with high flexural strength. Their quality control engineers fire tiles made with this new material at three different temperature settings (1500oF, 1800oF and 2200oF) and for four different times (2 hours, 6 hours, 10 hours and 12 hours). The response variable in this experiment is

Select one:

a. flexural strength.

b. firing time.

c. firing temperature.

d. the new material.

e. tiles

Explanation / Answer

The response variable for any experiment is the prime focus of that experiment.

In the given question, the prime focus is the high felxural strength.

Therefore, the response variable is a.flexural strength.
