a) correlational
b) naturalistic
c) experimental
d) observational

Answer 1

Answer:

Dr. Ingram conducted an C. experimental study.

Explanation:

An experimental study is that in which the variables are in direct control of the researcher. He/she is in control of changing or adjusting them in order to reach an outcome.

Dr. Ingram varied the imageability of items on a list to measure the participants' recalling abilities. He is conducting an experimental study.

Let's see why the other options are not valid in this case:

• A correlational study tries to find correlations between 2 or more variables.
• In a naturalistic study the researcher observes a certain phenomenon.
• An observational study just centers on observing, there is no manipulation of variables.
