Researchers at Griffin University (Australia) conducted a study to determine whether video game players have superior visual attention skills compared to non-video game players. (Journal of Articles in Support of the Null Hypothesis, Vol. 6, No. 1, 2009.) Each in a sample of 65 male students was classified as a video game player or a non-player. The two groups were then subjected to a series of visual attention tasks that included the “field of view” test. No differences in the performance of the two groups were found. From this analysis, the researchers inferred “a limited role for video game playing in the modification of visual attention”. Thus, inferential statistics was applied to arrive at this conclusion. Identify the relevant populations and samples for this study.
