You and your friend are trying to figure out if the training program at your summer camp is worth it. You collect everyone's jump average before and after completing the summer camp and want to know if there was actually a difference before and after the training program.

Medical researchers want to know if four different medications lead to different mean blood pressure reductions in patients. They randomly assign 20 patients to use each medication for one month, then measure the blood pressure both before and after the patient started using the medication to find the mean blood pressure reduction for each medication. What type of test is used to analyze the results?
ANOVA
Chi-Squared
T-test
Paired T-test
The medical researcher found that the ANOVA test showed that there was a significant difference in blood pressure averages for each medication. Does the ANOVA test show which medication worked best?
Yes, but you have to standardize the results
No, you have to perform a Bonferroni correction
No, you have to perform a Fisher's exact test
Yes, the ANOVA test will show which medication worked best
When would you perform a Fishers exact test?
It is a separate test performed when any results are unclear in research
After any Chi-squared test is done
After a Chi-squared test, but when there are less than 5 counts in one of the cells
After a Chi-squared test, but when there are less than 15 counts in one of the cells
This data was collected after a math exam to see if the males or females did better. The teacher decided to perform a Chi-squared test, was this the right test to perform on this data?
No, they should of performed a McNemar test
No, they should of performed a T-test
No, they should of performed a paired t-test
Yes, that would of been the correct test
If a study shows a p-value >0.05 what is said about the results?
The results are statistically significant
We reject the null hypothesis and accept the alternative
We fail to reject the null hypothesis
The results are statistically insignificant
In Bivariate analysis the null hypothesis states that there is no statistically significant difference between the groups you are testing and the purpose of these tests are to disprove or reject the null hypothesis
True
False
