Research Report Writing Assignment:
Task:
For this portfolio of statistical exercises you will be presented with four research questions and datasets which you need to conduct the relevant statistical test(s) for and write-up the findings in an appropriate format. You should attempt each question. The mark that you receive will reflect how well you have answered all four research questions and therefore missing any questions out will adversely affect you mark.
For each exercise requiring data analysis you are required to conduct and then report the findings of an appropriate analysis of the data provided in the reporting style that we have shown you during this module. You should screen the data prior to any analyses and routinely report appropriate estimates of effect size and other relevant statistical information where appropriate. You should also include appropriate and clearly expressed hypotheses.
You should include any calculations and all relevant SPSS outputs (e.g.., data screening checks, analyses, etc) as appendices.
For each question/exercise you should include the following sections:
1. Hypothesis or hypotheses: This should be clearly written and explain what you are testing for based upon the description of the research question.
2. Results: As stated above, in this section you should justify your selection of the test used and write up the results in the reporting style you have been shown.
3. Discussion: There should be a brief (i.e., a paragraph) discussion of the findings of the results in light of the research question.
4. Appendix: Please include any calculations and all relevant SPSS outputs for the question at the end of the answer to the question (in other words, don’t have a single appendix at the end with all of the outputs for all of the questions – it makes it more difficult for us to check them for an assessment like this).
Please note that staff members will not be able to help you to identify which test is most appropriate for the different questions as this is an important aspect of data analysis and one of the main aspects of your learning that this assessment is assessing.
Exercise 2
A cognitive development study was conducted in order to investigate if the manipulation of 3D objects can improve abstract reasoning in 8 year old children. In order to investigate this, children were divided into two groups: one group was given an abstract reasoning test, then given a LEGO building task for 30 minutes, and then given the abstract reasoning test again. The second group were given an abstract reasoning test, then asked to paint a picture for 30 minutes, and then given the abstract reasoning test again. It was anticipated that playing with LEGO would demonstrate the greatest improvement in abstract reasoning.
The following data were obtained from a sample of children (number of questions correct):
psyStats
Does playing with LEGO improve abstract reasoning in children more than painting a
picture?
Exercise 3
A social psychologist was interested in examining the effect of being observed on sports performance, and if competition can interact with this. He suspected that competition and observation would both make the cyclists faster. He measured a group of professional cyclists on how fast they rode the same distance under a series of controlled conditions. All the cyclists did all of the conditions. They rode the same distance on their own, and being observed by an audience of 20 people. They also rode the same distance at the same time as another cyclist (i.e., just the two of them with no audience), and when they were both being observed by an audience of 20 people.
The following data were recorded from the cyclists (time in seconds to complete the distance):
psyStats1
Does observation and competition pressure make cycling performance improve?
