Explain" rel="nofollow">in whether you thin" rel="nofollow">ink that this is the appropriate t test to use for the question. Why or why not?
As a lay reader, were you able to understand the results and their implications? Why or why not?
research Question
Do boys or girls spend more time playin" rel="nofollow">ing video games on a typical school day?
Null Hypothesis
Ho = boys spend less time playin" rel="nofollow">ing video games on typical school days.
Research Design
A quantitative descriptive research design would align with this research question. The research question is not askin" rel="nofollow">ing a why question so usin" rel="nofollow">ing a quantitative descriptive research design would be appropriate. The research question is simply tryin" rel="nofollow">ing to fin" rel="nofollow">ind what currently exists and the data collected could be used for future research.
Comparison Means Test Used
Usin" rel="nofollow">ing SPSS, an in" rel="nofollow">independent samples t-test was calculated. Sin" rel="nofollow">ince the in" rel="nofollow">independent samples t-test can only test two means at a time to fin" rel="nofollow">ind the difference (boys and girls), this test was decided to be the most practical to use (Laureate Education, 2016). The in" rel="nofollow">independent samples t-test shows if there is a difference between the means.
Dependent and Independent Variables
The dependent variable used for this statistical testin" rel="nofollow">ing was hours spent playin" rel="nofollow">ing video games on a typical school day. This was the test variable where the mean is calculated on (Laureate Education, 2016). The in" rel="nofollow">independent variable was T1 student’s sex. This was the groupin" rel="nofollow">ing variable.
Fin" rel="nofollow">indin" rel="nofollow">ings
Within" rel="nofollow">in the group statistics, the followin" rel="nofollow">ing in" rel="nofollow">information was calculated: Males N = 10323 with a mean of 2.30, standard deviation of 1.639 and standard error of mean .016; Females N = 9887 with a mean of 1.30, standard deviation of .882 and standard error of mean .009.
The next step was to study the in" rel="nofollow">independent samples t-test produced by SPSS. The first area of examin" rel="nofollow">ination would be the Levene’s test, which tests the null hypothesis showin" rel="nofollow">ing the variances are equal. The Sig. or p-value shows a .000, which gave the in" rel="nofollow">indication with high probability that the null hypothesis could be rejected. Choosin" rel="nofollow">ing the equal variances not assumed lin" rel="nofollow">ine the t statistic showed 54.601 with the associated p-value of .000 which shows that the results are statistically significant at the .001 level (Laureate Education, 2016). The mean difference between boys and girls is 1.005. The 95% confidence in" rel="nofollow">interval of the difference gave a lower of .969 and an upper of 1.041.
Research Question Answer
To refer back to the research question, do boys or girls spend more time playin" rel="nofollow">ing video games on a typical school day, the statistical testin" rel="nofollow">ing conducted showed that there was a difference in" rel="nofollow">in the number of hours’ boys spend more time playin" rel="nofollow">ing video games on a typical school day over girls.
