Purpose of the Laboratory Report The assignment will give you hands on experience writing a laboratory report that extends a published study. You will critically analyse the published study and use the key findings from this research when writing the Introduction of your own report. You will also be given a data set on a hypothetical study and be required to analyse the data set to test hypotheses that you develop.
The assignment help translate much of the theory that you have learned during the lectures into practice. The skills you have learned in the critical analysis of research, and the use of SPSS in the tutorials, will be used to produce the report. The laboratory report will also develop your written communication skills.
Laboratory Report Requirements Summary of the requirements for the laboratory report:
The five requirements of the laboratory report are detailed below.
This assignment will be based on a hypothetical data set that aims to extend the research by Tong et al. (2008). You will need to download and read the article. The reference for the article is below (and the article is available on ): Tong, S. T., Van Der Heide, B., & Langwell, L. (2008). Too much of a good thing? The relationship between number of friends and interpersonal impressions on Facebook. Journal of ComputerMediated Communication, 13, 531-549. doi: 10.1111/j.1083-6101.2008.00409.x
You will find that the study is not perfect and that there are a number of concerns regarding the methods, and consequently, the results. Think critically about the study and see if you can identify threats to validity, problems with the methods, and the appropriateness of the author’s conclusions.
You can be guided by the questions below:

You will need to use the data set supplied to you to answer the following research questions:
A good starter reference that provides additional information regarding upward and downward social comparisons, and self-esteem, is provided below: Greitemeyer, T. (2016). Facebook and people’s state self-esteem: The impact of the number of other users’ Facebook friends. Computers in Human Behaviour, 59, 182-186. doi: 10.1016/j.chb.2016.02.005 3.
Conduct appropriate statistical analyses on the data set To decide what analyses are appropriate to use to test your stated hypotheses, it will help to think about the following questions: · How will you create your variables with the data set? (think about the information included in the data file “variable view” and whether this information is complete) · What dependent variable(s) will you use? ·
How will you screen your data for accuracy, completeness, and for the necessary assumptions for your subsequent analyses? What descriptive statistics will you use? · What are the important components of your one-way ANOVA (e.g., levels of the independent variable) and how will the analysis directly test your research hypotheses? · What effect size measures will you use? In answering these questions, be guided by the following: · You should use what you have learned in Lectures 1-4 to conduct your analyses.
This will be appropriate assumption testing, the one-way ANOVA, and any necessary multiple comparisons. · While we will also be learning about other ways to conduct analyses before the assignment is due (e.g., Factorial ANOVA), these analyses should not be included in the assignment. · You will need to report the findings from the assumption testing for the ANOVA’s you conduct.
You will need to report the means for each group, for both dependent variables, as well as a measure of variability around the mean (i.e., standard deviation). · You will need to report the outcomes of the inferential tests you conduct. When conducting your multiple comparisons, you must use planned contrasts. There are several ways to run the planned contrasts to test your hypotheses.
However, an example of how you could go about this is provided below (note: green ‘chunks’ are compared with blue ‘chunks’ and black groups are excluded from the contrast). The numbers in the table below represent the experimental group, not the contrast coefficients – you will need to create your own contrast coefficients to run these analyses.
If you would like to run alternative planned contrasts to those outlined below, please discuss this with your tutor in the first instance to make sure what you are proposing still tests your hypotheses:
The title page will include an appropriate title, your name and affiliation, plus the number of words in the report. The number of words excludes the title page, text already included in the template document, and references.
The abstract must include a summary of the report that is a maximum of 150 words. In concise language, it should describe the objectives, methods, results, and conclusions.
Introduction You must have an opening paragraph that places the research in context, including prior research, and justifies the importance and need for the research. Note that while you are expected to do a brief literature review, this does not have to be extensive (not a lot of marks are allocated to this part of the Introduction).
You must do a critical analysis of the method and results reported by Tong et al. (2008).
You must finish with a paragraph that states the general research questions (in your own words) and hypotheses.
Method (Participants) You must describe the participants in terms of all relevant demographic variables.
You must describe the independent variable and its levels, and the dependent variable(s). The statistical approach should be described including information on assumption testing methods (and the outcomes), inferential statistical methods, effect size measures, Type I error rates used, and other information as appropriate.
The outcomes of the statistical tests you used must be presented. Relevant effect sizes must be presented. Using the one-way ANOVA, you must test whether there were any main effects. Use multiple comparisons to compare between means where appropriate. The analyses must be reported and should be relevant to the research hypotheses being tested.
A Table must be presented that shows the means and standard deviations (or another appropriate measure of variability around the mean) for both dependent variables. The Table title must be appropriate. The Table must be described adequately in the text. Do not copy a Table directly from the SPSS output into your report.
You must include a summary of the results in relation to the hypotheses that were tested. You must include an interpretation of the results. 8 You must raise any methodological or statistical concerns or limitations (e.g., issues of reliability, validity, or confounding variables). You must discuss the implications of the results and state future directions. There must be a conclusion.
APA Style (References and Writing Style) You must provide the references for research articles that you cited in the report (both in-text and in a reference list). Marks will also be allocated for APA formatting and writing style. 4 Summary Comments: 100 * For all sections, writing style and APA formatting must be appropriate
