Answer #1

Dependent t test compares the means between two related

Groups on the same dependent variable.

As per question dependent variable is performance of exam

and groups to compare is "studying before the students go to bed " and "studying during the day".

This type of test will be handled by paired t test .

Paired t-test is dependent t-test.

ANOVA is used in case of more than two variables to be compared.

One sample t-test is used when mean of only one set of data is to be tested.

Independent t test is applied when there are two set of data and not having same dependent variable.

INDEPENDENT SAMPLES T-TESTS A researcher was interested in testing whether alertness levels differed in those who drank a cup of coffee versus those who drank an energy drink. She randomly assigned participants to one of the two conditions and then showed them a five-minute video. After the video, all participants completed a questionnaire measuring their memory for things that had been presented in the video. Higher scores = better recall. Perform an appropriate two-tailed test of the significance of the...

A researcher wants to know whether supplements affect how long vampires can go without requiring human blood. She took one sample of vampires (n = 13). Half received a placebo first and the supplement second, while the other half received the supplement first and the placebo second. She then recorded how many days the vampires could go without consuming human blood for each condition. The goal of the study was to see whether there would be any difference between supplement...
