Extraneous
An <em>extraneous variable</em> is a variable in an experiment that you are not intentionally studying. These variables usually provide undesired affects on the experiment.
In this example, the independent variable is whether a sentence is humorous or not, and the dependent variable is the memory performance score. However, because the humorous sentences are only given to males, and the non-humorous sentences are only given to females, gender becomes an extraneous variable as you are not intentionally testing gender's relation to the dependent variable, but it is still affecting the experiment.

Answer:
- Explanatory
Explanation:
<u>Explanatory variable</u> is elucidated as the variable that could affect the response variable. This variable is quite identical with the independent variable as it can be controlled or changed that may affect the response variable(which is similar to dependent variable). However, the observational studies observe the natural responses without any manipulation and therefore, these variables cannot be changed always. In the given example, the 'number of hours spent on studying for the test' would be the explanatory variable as it directly influences the response variable i.e. 'grades.'
