The measure of cleaning behavior was subjected to a ______. Participants removed

Question

The measure of cleaning behavior was subjected to a ______. Participants removed the crumbs substantially more often in the scent condition (M = 3.54) than in the control condition (M = 1.09), t(20) = 2.37, p = .02, thus showing a direct link between scent perception and behavior.

1. What kind of study design is this (experimental or correlational)?

2. If experimental, what is the independent variable?

3. If experimental, what is the dependent variable?

4. What kind of statistical test did the author run, and how do you know the used this test?

5. What do you think the null and alternative hypotheses are in this study?

Explanation / Answer

This is an experimental study design. In this experimental, study the independent variable is; scent condition as this is the variable that we can change. In this experimental, study the dependent variable is; removing the crumbs; as this is the variable that we will record i.e. observe. A t-test for statistical significance was conducted in this experiment to find the significance level of the finding i.e. p-value; which is given as 0.02
