Question

1. A researcher is interested in seeing if playing violent video games leads to a change in aggressive attitudes. The researcher recruits an experimental group, who plays a violent video game for 1 hour, and a control group. Both groups complete a measurement instrument that measures their aggressive attitudes on a scale of 0-100.

   A. What type of study design is this (descriptive, correlational, or experimental)?

   B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson correlation, one sample t-test, paired samples t-test, independent samples t-test, or ANOVA)?

Answer 1

A. Clearly researcher is trying to find the relationship among variables namely aggressive attitudes and playing violent video games. For this he deviced two experimental groups who played violent and non violent video games. Thus experimental study design is used here.

B. Independent sample t-test would be appropriate to use as the model assumes that a difference in the mean score of the dependent variable (which aggressiveness) is found because of the influence of the independent variable (which is playing violent video games) this feature distinguishes the two groups. that distinguishes the two groups.
