Introduction
- Choose a study to focus on and a theory that it can explain,
- Give a brief summary of the study
- Explain the theory or model you are exploring in detail.
- Connect the study and theory together
- Explain the aim of the study and why it is significant/ worth exploring
- Provide the operationalized independent variable and dependent variable
- Provide the research hypothesis and null hypothesis.
Exploration
- Explain the procedures of the experiment you replicated (It is okay to change some things from the original study)
- Explain the reserach design you used and why.
- Explain the sampling method used (ex: Convience Sampling) and why you chose that.
- Explain in detail the sample that was used and relevant information about the participants; Explain why you asked the participants the specific questions prior to the experiment.
- Explain what you controlled for in the experiment, how, and why.
Analysis
- Provide a table for descriptive statistics with central tendency (mean, median, or mode) and dispersion (range, stand dev, or interquartile range)
- Summarize how you measured your DV.
- Explain and Summarize the results from the table, what they mean, and their significance.
- Prvoide your interpretation of the results based on your hypothesis.
- Provide the graph of your results that includes your measure of central tendency (this can include the mean)
- Inferential Statistics: Explain if your data was unrelated (independent samples design) or related (repeated measures design). State your level of measurment is at least ordinal so you chose to use either Mann-Whitney U Test (Independent Samples) or Wilcoxon Signed Ranks Test (Repeated Measures)
- On a Mann Whitney U Test: Calculate U value, critical value based on n^3 value, and the P value
- If doing a Wilcoxon Test, calculate the W value, critical value based on n^5, U value, and P value.
- Either accept or reject the null hypothesis.
Evaluation
- Explain how the results of your study compare to the original.
- Explain how the results relate to your theory or model.
- Provide a Strength and Limitation for the Design, Sample, and Procedure.
- The limitation should not include researcher error.
- Give a one sentence conclusion.
