From what you have been taught previously and the slides on Moodle, please complete the required exercises below in relation to data scenario 1 (the 1st sheet of the Excel workbook associated with this task and available on Moodle). (10 marks total for scenario)
1) In terms of N.O.I.R. what kind of data do you have here? (1 mark)
2) Using prism, the statistics flow chart and the nature of the data set, what statistical tests will you need to conduct to compare all the groups? In your answer, Please walk through the steps of the flowchart showing what final tests you would do (e.g. ANOVA/T-Test/Kruskal-Wallis/Fishers etc.).
Ensure you describe what normality tests have you done, what variance tests are you using and how this information dictates what final test you have done. (you will need to analysis the data in prism to achieve this answer). (4 marks)
3) Is there a statistical difference between (all) the groups? report this as; the test that was done, the P value, and whether or not this is statistically significant (assuming threshold of P<0.05 for significance). (3 marks)
4) These tests have given you a fair amount of statistical/mathematical information but what infrences and interpretations can you make from these statistics in the context of the specific scenario (e.g. is this finding of note? are there potenial confounds? Etc.) – give 2 examples of potential inferences / interpretations you could make? (2
