class: center, middle, inverse, title-slide # t-test and Red Study ## Practical 07 ### Jennifer Mankin ### 11 - 12 March 2021 --- <script type="text/javascript"> setup() </script> ## Today's Tasks - Overview of the Lab Report - Red Study Design - Work on the Red Study Replication --- ## Overview of the Lab Report - Second half of a "typical" lab report/journal article - Design, Results, Discussion, and References - 1000 words **max** limit - Choose Red study (this week) or Green study (last week) <br><br> .center[Full information on the [Lab Report Information and Resources page on Canvas](https://canvas.sussex.ac.uk/courses/12727/pages/lab-report-information-and-resources)] --- ## Timeline of the Report - Last week: Green study analysis - This week: Red study analysis - Week 8: Writing up Results - Week 9: Submit! --- ## Template Documents - Your choice of two document options: Markdown or Word/Script - Markdown: Do analysis, create plot, and write report in RMarkdown document; knit to Word - Word/Script: Do analysis and create plot in script, write report in Word document - Either way, submit a Word document! --- ## Summary of Results - In either document type, enter a few particular numerical results from your analysis in the "Summary of Results" section at the beginning - Your data is unique to you, so **each person will have different numbers** - Do not delete or move this section! - Complete once your analysis is done - Does **not** contribute to your word count - Has been updated since last week; please **download again** and use the new version! --- ## Academic Integrity - In general, you can support each other, but you must each prepare and produce your own report - Fine: sharing papers for background reading, discussing papers/theories, problem-solving code together, helping each other debug errors - NOT fine: copy/pasting code, sharing any text or code, working together on a single document <br><br><br> .center[ [Full description of misconduct guidelines on Canvas](https://canvas.sussex.ac.uk/courses/12727/pages/assessment-and-misconduct-information) ] --- <br><br><br><br><br> ## Questions? --- ## Red Study Design - Original paper: Elliot et al. (2010) - Interested in the relationship between colour and attraction - Participants viewed a greyscale photo of a man for 5 seconds - Randomly assigned to one of two conditions: - Photo had a white frame (control) - Photo had a red frame (experimental) - Then asked to rate the man on three scales of attractiveness - What did the original paper predict? What do *you* predict? --- ## Red Study Design - For the report/practical, assume that we performed a *replication study* - Same study design, variables, stimuli, etc. - Different sample of people - Key question: Does this experiment **replicate**? - That is, do we get the same result/find the same effect? - What does that tell us about our research question? --- ## Getting Started - Choose your document type - Create a `report` or `week_07` project (if you haven't already) - Follow the tasks in the worksheet - Use the tutorial if you get stuck! - As usual, we will have a break partway through for the PIN --- class: last-slide <br><br><br><br><br> # And that's it!
