Question

A researcher examined whether college students were better at remembering certain categories of words than others. All participants were shown 12 words and were then asked to write down as many as they could recall. The researcher randomly assigned participants to one of 3 conditions: 25 participants were shown words that were professions (e.g. waiter, secretary); 25 different participants were shown words that were foods (e.g. apple, broccoli); and a third group of 25 participants were shown words that were animals (e.g. dog, zebra).

1.Clearly identify the IV

2.Clearly identify the levels of the IV (conditions).

3.What is the level/scale of measurement of the IV? Explain your answer.

4. Clearly identify the DV.

Explanation / Answer

1. The IV is "word categories" because the researcher is using different sets of word categories to find its effect on memory (being able to remember it).

2. The levels of the IV include professions, foods, and animals. This is stated as "conditions".

3. The scale or level of measurement is nominal. This is because these are categories that only have a name or a label. They do not have any numerical value, nor can they be ranked against one another.

4. The DV is memory/ability to remember. As explained in the first part of the question, the IV is being manipulated to ultimately study its effect on this.
