Question
Scenario 3
Suppose a professor is interested in seeing whether or not gum can be used as a successful retrieval cue for
course material. To test their hypothesis, they randomly assign sections of their statistics class to receive gum or
receive nothing during their review sessions and subsequently during their exam. They randomly select a subset
of students scores from each section. Use the data on the next page to help calculate the appropriate t-statistic
for the research question and engage in hypothesis testing to determine if the professor's hypothesis was
supported.

11. Using the data provided, determine the null and alternative hypotheses. Then determine how many tails this
research question has.
12. Using the data provided, recreate this table in Excel and use what you have learned to calculate the means
for each group and use what you have learned in class to calculate the t-statistic associated with this research
question.
13. Using Appendix B in your text, the degrees of freedom for this research question, and the number of tails
your hypothesis has to determine the t-critical value
10. Based on your calculated t-statistic and t-critical value, engage in hypothesis testing. What is your decision
regarding the research question
15. Reporting your t-test results in APA: Using the template below, report the findings of your t-test analysis in
ΑΡΑ.
"The current study examined the influence of (your IV) on (your DV). To determine whether group differences
were observed, an independent-samples t-test was conducted to compare the effects of [insert your DV here] in
[insert your IV level 1 here] and [insert your IV level 2 here]. The independent samples t-test revealed (or failed
to reveal if you did not find significant difference) a significant group difference for [IV level 1] (Mx = XX.XX.
SDx = 3.98) and [IV level 2] (My = XX.XX, SDx= 4.83); t(df)= X.XXX, p<(or > if not significant) 0.05].
*Then you will restate this finding in your own words where you compare the performance of your two
groups (levels of IV) on your dependent variable (DV).*
(For example: These results suggest that individuals in group 1 tended to report/score/etc. higher (or lower) than
individuals in group two.)"
