Imagine you are developing a standardized research protocol for an upcoming psychology experiment. Based on the concept of p-hacking, describe three specific, actionable rules you would implement in your data analysis plan to prevent researchers in your lab from arbitrarily manipulating their data to artificially inflate their chances of obtaining a statistically significant result.
Question: Imagine you are developing a standardized research protocol for an upcoming psychology experiment. Based on the concept of p-hacking, describe three specific, actionable rules you would implement in your data analysis plan to prevent researchers in your lab from arbitrarily manipulating their data to artificially inflate their chances of obtaining a statistically significant result.
Sample answer: To prevent p-hacking in our lab, I would implement the following three rules. First, researchers must pre-register all dependent variables before data collection begins to prevent selectively reporting only the variables that yield a desirable -value. Second, the criteria for removing outliers must be explicitly defined and justified prior to analysis, ensuring no arbitrary removal of data points just to achieve significance. Third, researchers must report all findings, regardless of whether they are statistically significant or not, to prevent selectively presenting only the significant results.
Key points:
- Establish strict, predefined criteria for outlier removal to prevent arbitrary data exclusion.
- Commit to analyzing and reporting all dependent variables measured in the study.
- Present all findings, including non-significant results, rather than selectively reporting only significant ones.
Rubric: Full credit requires identifying three distinct rules that directly address the mechanisms of p-hacking mentioned in the text (e.g., selective reporting of variables, arbitrary outlier removal, selective presentation of findings). Partial credit is awarded if fewer rules are provided or if the rules do not directly address the prevention of data manipulation meant to achieve a desirable -value.

Analyze Dr. Smith's analytical decisions in the provided case study. Identify the specific practices she engaged in that constitute p-hacking, and explain the direct consequence these actions have on the published psychological literature.
A fellow psychology student argues, 'As long as a researcher eventually achieves a desirable -value, the analytical decisions they made along the way—like removing a few outliers or choosing which dependent variables to report—are justified because the significant result proves the phenomenon is real.' Evaluate this argument based on the concept of p-hacking and its impact on statistical error rates.
p-hacking involves making arbitrary analytical decisions to artificially inflate the chances of obtaining a statistically significant result. Match each specific p-hacking practice to its corresponding description.
A researcher establishes a strict mathematical rule for identifying outliers before beginning data collection. After collecting the data, they apply this pre-established rule and remove three participants whose scores fall outside the acceptable range, which subsequently results in a significant -value. This analytical decision is an example of p-hacking.
A researcher conducts an experiment to test a new therapy but engages in p-hacking by selectively reporting dependent variables. Arrange the following events in the correct chronological order to analyze how this specific mechanism of p-hacking unfolds to artificially inflate the chance of a significant finding.
