Quasi Experimental Design: Check the Comparator

Read a quasi experimental design by checking treatment assignment and the comparator. Build a source-linked note that keeps planned methods apart from results.

Questionnaire design with a checked item-alignment note

Plan questionnaire design with a worked item-alignment table. Connect constructs to wording, answer choices, source requirements, and checks before testing.

Quota Sampling: Examples and Recruitment Checks

Quota sampling fills preset groups without random selection. Learn its types, calculate a worked quota, and check recruitment rules before interpreting results.

Quote Integration With Context and a Worked Example

Learn quote integration with a worked paragraph and source checks. Introduce exact words, preserve their context and explain how they support your own claim.

Random Sampling vs Random Assignment: Check the Stage

Random sampling vs random assignment separates who enters a study from who receives a condition. Compare their purposes and check a worked methods example.

Recall Bias: Compare the Memory Task Across Groups

Understand recall bias with a worked study example. Compare time windows, prompts, and collection conditions before judging a claim about past exposure.

Registered Report: Check the Plan, Stages, and Changes

Read a registered report with a worked plan-to-report note. Check Stage 1 approval, the registered protocol, changes, and planned versus exploratory tests.

Reliability vs Validity: Read the Evidence Separately

Compare reliability vs validity with examples and a worked evidence note. Learn what consistency supports, what it cannot prove, and which passages to check.

Replicability vs Reproducibility: Check the Evidence

Understand replicability vs reproducibility by checking whether a report reuses original data or collects new data. Keep methods, results and gaps visible.
