Choose the BEST method for the situation:
Two different methods of teaching number division in two respective samples of elementary school students were compared using a test of division ability, which was administered at the end of the study. In addition, the children were also measured at the beginning of the study on an intelligence test yielding an intelligence score. You want to know if there are differences between the two methods using the data that you have collected.

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....

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...

A graduate student is interested in whether journaling can affect grief and healing. She has participants who have been widowed within the past 10-14 months complete a battery of psychological questionnaires before and after journaling about their daily problems for 2 months. The first time the graduate student conducted this study, she used a repeated-measures design and compared the widows' and widowers' baseline scores with their scores...

A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. Basal is the traditional method of teaching, while DRTA and Strategies are two innovative methods based on similar theoretical considerations. The READING data set includes three response variables (posttests) that the new methods were designed to improve. Analyze The Posttest 2 score using ANOVA. a. What is the response variable? Method of instruction Traditional teaching method Innovative...

Discussion 3 Msn 602 Read this fictitious study and then answer the questions that follow: Brusser and Joansy wanted to test the effectiveness of a new relaxation/biofeedback intervention on menopausal symptoms. They invited women who presented themselves in an outpatient clinic with complaints of severe hot flashes to participate in the study of the experimental treatment. These 50 women were asked to record, every day for 3 weeks before the intervention, the frequency and duration of their hot flashes. The...

4. Repeated-measures ANOVA Aa Aa Suppose you are interested in studying whether lighting brightness affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores for the paper-folding test with five people, repeating the test on each person with three different lighting levels (800, 1,000, and 1,200 lux) In this experiment, the null hypothesis is that: O There are no individual differences in the completion time means O The completion time mean for at least one lighting...
