Question

Subjects in the weapon condition were only slightly, but not significantly, less accurate than controls on the 20-item questionnaire. Weapon present subjects were correct on 45.8% of the items, while control (weapon absent) subjects were correct on 50.3% of the items, t(34) = 1.37, p > .05, one tailed.

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?

Explanation / Answer

1) From given information we use experimental study design.

2) Independent variable is Weapon present subject were correct on 45.8% of the items.

3) Dependent Variable is control (weapon absent) subjects were correct on 50.3% of the items.

4) Here, use statistical t-test.  Because, Here given that the t-value, i.e. t-test (one tailed). Here null hypothesis is, Subjects in the weapon conditions are not significant. Alternative hypothesis is , Subjects in the weapon conditions are significant.
