Clearly identifying the independent and dependent variables in a study is a critical aspect of any research project. The dissertation is no different. This assignment will allow you to practice your skills in identifying research variables.

General Requirements:

Use the following information to ensure successful completion of the assignment:

• In a study investigating the effects of humor on memory, Schmidt showed participants a list of sentences, half of which were humorous and half were non-humorous. Schmidt found that participants consistently recalled more of the humorous sentences than the non-humorous sentences, demonstrating that the use of humor increased participants' recall of sentences.
