Question

Professor Nakum designs a memory experiment to test the effect of word familiarity on memory. Three lists of words are created: common words, uncommon words, and made-up words. Participants are randomly assigned to study one of the lists of 30 words for 5 minutes, do math problems for 5 minutes, then write all the words they recall from the list. Their score is the number of words correctly recalled.
Required:
What is the independent variable in this study?

Answer 1

Answer:

the type of word list

Explanation:

An Independent Variable is a form of a variable in an experiment or research study in which the investigator or researcher alters or regulates with the purpose of having a straightforward impact on the dependent variable.

Hence, in this situation, the independent variable is: "the type of word list" which has an impact on the dependent variable "the number of words correctly recalled."
