In planned analyses, which set of procedures is typically used when researchers are investigating anticipated differences between groups?

Planned analyses in psychological research are selected based on whether a study focuses on comparing groups or examining relationships. Match each research goal with the statistical or visual procedure that typically belongs in its analysis plan.

A researcher is planning a study to compare the average test scores of students who used a new educational software versus those who used traditional textbooks. Arrange the components of the researcher's planned analysis in the logical order they should be conducted to evaluate these group differences.

A researcher investigates whether a new mindfulness intervention reduces anxiety by comparing an 'intervention' group to a 'control' group. If the researcher plans to calculate Pearson’s $r$ as the primary effect size to quantify this group difference, the analysis plan is flawed because Pearson’s $r$ measures the correlation between variables rather than the standardized difference between group means.

Imagine you are drafting the 'Data Analysis' section of a research proposal for a study designed to compare the average memory test scores of a 'Treatment' group versus a 'Placebo' group. Which of the following outlines the most appropriately constructed and comprehensive analysis plan for this research project?

True or False: In a psychological study designed to examine expected correlations between variables, the planned analysis typically involves calculating Cohen's $d$ and creating bar graphs.

A researcher is planning a study to examine an expected correlation between two psychological variables. Arrange the steps of the planned analysis in the correct logical order, starting from the initial inspection to the final statistical calculation.

A researcher is critiquing an analysis plan for a study where a correlation is expected between variables. The plan includes calculating Pearson's $r$ but does not specify any visual check of the data. The researcher argues that the plan is inadequate because it fails to include a(n) _____, which is required to evaluate the data for potential nonlinearity or restriction of range.

A researcher is planning two studies: Study A compares test performance between an experimental group and a control group, and Study B examines the relationship between weekly exercise hours and resting heart rate. Match each research scenario or component with its appropriate planned analysis tool based on the research design.

An evaluator is assessing a draft of a research proposal where the authors plan to study the correlation between study duration and test scores. The proposal outlines generating scatterplots and calculating Pearson's $r$. The evaluator notes that this analysis plan is incomplete because it fails to evaluate the dataset for potential distortion due to nonlinearity and _____ of range.
