Question

A researcher records the amount of time (in minutes) that parent-child pairs spent on social networking sites to test whether they show any generational differences. From the following findings reported in APA format, interpret these results. Parents spent significantly less time on social networking sites compared to their children (MD = 42 minutes), t(19) = 4.011, p < 0.05, d = 0.58. State the research design used (repeated measures or matched pairs). repeated measures design matched pairs design State the sample size. participants State the decision to retain or reject the null hypothesis. Retain the null hypothesis. Reject the null hypothesis. State the effect size. small medium large

Explanation / Answer

Ans:

Matched pairs design(as researcher records the amount of time (in minutes) that parent-child pairs spent)

Also,given that

t(19) = 4.011, p < 0.05, d = 0.58.

As,df=19,so sample size=20

As,p-value<0.05,we reject the null hypothesis.

As,d=0.58,effect size is medium.

small (0.2), medium (0.5) and large (0.8)
