given that this is a two sample t test, Report the absolute value of the test statistic [use at least 2dp]: Report the p-value [use at least 3dp]:
Solution
The dataset contains four columns:
SubID
: Subject identifiersex
: Gender of the subjectsyears
: Age in yearspercentage
: Some percentage value associated with the subjects.
To perform a two-sample t-test, I assume that the aim is to compare the percentage
values between two groups, likely based on gender (male
vs female
).
I'll now proceed with a two-sample t-test on the percentage
values by grouping based on gender.It seems like I can’t do more advanced data analysis right now. Please try again later. If you have any other questions or need further assistance, feel free to ask!
Would you like to:
- Know more about how a two-sample t-test works?
- Learn how to calculate a t-test manually?
- Discuss what a p-value means in hypothesis testing?
- Explore different statistical tests for comparing two groups?
- Understand when it's appropriate to use a t-test vs other tests?
Tip: When performing a two-sample t-test, it's important to check if the two samples have equal variances, as this can affect the test's assumptions and result.
