Which statistical test is used for parametric testing when analyzing differences across more than two groups?

A research team is analyzing data from a study on the effects of different therapeutic interventions on depression scores. Match each analysis scenario to the most appropriate statistical test.

A psychology researcher is investigating the effects of three different levels of social stress on interferon activity. According to the provided statistical protocol, the researcher should use an ANOVA to analyze the differences in scores between these three groups.

A researcher is following a statistical protocol to identify and analyze interferon (IFN) activity across different patient groups. Based on the logic of establishing thresholds and comparing groups, arrange the following steps in the correct methodological sequence.

In the protocol for identifying biomarkers, a positive interferon (IFN) signature is denoted when a score is higher than $2 \text{ SD}$$ of the mean IFN scores of the control group.

Based on the described protocol, what is the primary reason for plotting ISG values and interferon (IFN) scores logarithmically before conducting parametric tests like $t$ tests or ANOVA?

A peer reviewer is critiquing a study's analysis of the relationship between patient age and CSF interferon activity. To evaluate whether the study follows the established protocol for these biomarkers, the reviewer should verify that the authors used a(n) _____ rank correlation.

A clinical psychology researcher is investigating immune biomarkers in patients with Aicardi-Goutières syndrome. The control group has a mean interferon (IFN) score of 12.5 with a standard deviation ($SD$) of 3.0. According to the study's protocol, patients in the experimental group will be classified as having a positive IFN signature if their IFN score is strictly higher than ____.

A clinical psychology researcher is analyzing interferon-related biomarkers in patients with Aicardi-Goutières syndrome. To ensure the statistical integrity of the study, the researcher must align each methodological step in the protocol with its correct analytical or statistical rationale. Match each methodological action to the corresponding rationale that justifies its use.

Imagine you are a peer reviewer evaluating a submitted manuscript that investigates immune biomarkers in patients with Aicardi-Goutières syndrome. The authors analyzed their data to determine interferon (IFN) signatures, compare IFN scores across three patient groups, and correlate IFN activity with age. To systematically evaluate the statistical integrity and validity of their findings, arrange the steps of your methodological audit in the correct logical sequence, starting from raw data pre-processing evaluation to inferential test appraisal.
