For each example, state whether the one-sample, the two-independent-sample, or the related samples t-test is most appropriate. If it is a related samples t-test, indicate whether the test is a repeated measures design or a matched-pairs design.
1) A researcher matches right-handed and left-handed siblings to test whether right-handed siblings express greater emotional intelligence than left-handed siblings.
A. one-sample t-test
B. two-independent sample t-test
C. related samples t-test using the repeated measures design
D. related samples t-test using the matched-pairs design
2) A professor tests whether students sitting in the front row score higher than students sitting in the back row.
A. one-sample t-test
B. two-independent sample t-test
C. related samples t-test using the repeated measures design
D. related samples t-test using the matched-pairs design
3) A graduate student selects a sample of 25 participants to test whether the average time students attend to a task is greater than 30 minutes.
A. one-sample t-test
B. two-independent sample t-test
C. related samples t-test using the repeated measures design
D. related samples t-test using the matched-pairs design
4) A principal at a local school wants to know how much students gain from being in an honors class. He gives students in an honors English class a test prior to the school year and again at the end of the school year to measure how much students learned during the year.
A. one-sample t-test

Problem Set 7.1: t Test with Related Samples Criterion: Differentiate between independent samples, repeated measures, and matched samples. Data: Scenario A: A researcher wants to know whether men or women spend more money at the movie concession stand. He asks the concession clerk to identify customers as male or female by marking their gender on each saved receipt. Scenario B: A CPR instructor wants to know if her students are learning anything during her 90-minute training. She decides to quiz...

2. Identifying related samples Aa Aa E For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers can match subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples.) Lorrin Koran has studied whether antidepressants are effective for treating kleptomania. Suppose that people with kleptomania typically score...
6. Engagement Activity: The t Test for Two Related Samples
6. Engagement Activity: The t Test for Two Related Samples In the last chapter, you were introduced to Professor Ken Bonanno's Statistical Methods in Psychology class, where students are asked to complete a research study as a part of the semester-long course. Many of his students' research questions could be asked using the independent-measures t test, but there are other approaches, which will be explored in this chapter. Click the following topics to see some sample questions asked by Professor Bonanno's students....

Which research design would not be appropriate to analyze using a related-samples t-test? matched-pairs design collecting data from identical twins randomly assigned to one of two conditions repeated-measures design collecting data from the same set of participants who experience two conditions between-subjects design collecting data from two separate sets of participants randomly assigned to one of two conditions pre-post design collecting data from the same set of participants before and after undergoing a manipulation

5. A two-tailed hypothesis test for a repeated-measures design A graduate student is interested in whether jounaling can affect grief and healing. For her study, she selects a random sample of 64 adults who have been widowed within the past 10 to 14 months. The subjects complete a battery of psychological questionnaires before and after spending two months journaling about their emotions. Before the two months of journaling, the mean score on the impact of event scale-avoidance subscale, which measures...
