Research Design and Methods RCH 5301 DB V Peer Response

**Unit V Assignment**

Then, choose a peer(s) response and make a case for using the opposite analytical approach (e.g., If your peer(s) advocates using a test of relationships, such as simple regression analysis, to address their dilemma, make a case for using a test of differences, such as the t-test).

**Peers Post**

**The dilemma I am going through at work is that roofers aren’t complying with safety protocols. We want to understand which factors relate to non-compliance and, if possible, identify differences between compliant and non-compliant groups. Two non-experimental strategies can help: correlational analysis and causal-comparative analysis. Each has its strengths depending on your research goals and data structure.**

**Correlational analysis examines the strength and direction of relationships between two or more variables without implying causation.**

·
**Use when you have continuous or ordinal measures (e.g., hours of training, safety-climate score, frequency of toolbox talks) and want to see how they co-vary with compliance rates.**

·
**Pros:**

·
**Identifies key predictors for non-compliance.**

·
**Supports multivariate models (e.g., multiple regression) to control for confounders.**

·
**Cons:**

·
**Cannot establish cause-and-effect.**

·
**Sensitive to outliers and non-linear relationships.**

**Application: Measure each worker’s compliance score (e.g., % of tasks using fall-arrest systems) alongside potential predictors, then compute Pearson or Spearman correlations and regression coefficients to pinpoint the strongest associations.**

**Causal-Comparative Analytical Approach**

**Also known as “ex post facto,” causal-comparative compares naturally occurring groups on outcome variables without researcher manipulation.**

·
**Use when you already have distinct groups (e.g., roofers who comply vs. those who don’t) and you want to compare their mean differences on factors like training hours or safety-culture ratings.**

·
**Pros:**

·
**Simple group comparisons (t-tests, ANOVA) quickly highlight significant differences.**

·
**Useful for profiling non-compliant cohorts.**

·
**Cons:**

·
**Still no true causality—preexisting group differences may bias results.**

·
**Requires clear, reliable group classification.**

**Application: Divide participants into “compliant” and “non-compliant” based on a threshold, then compare average training frequency or equipment availability scores between the two groups.**

**If the primary goal is to uncover which factors most closely relate to non-compliance—and to build predictive models—start with a correlational approach. It will help you prioritize interventions by showing which variables carry the strongest statistical ties to unsafe behavior.**

**If you already have a reliable way to classify roofers into compliance categories and want to profile differences, a causal-comparative approach can quickly reveal which group characteristics stand out.**
