Check Dose-Response Patterns

This method examines the relationship between the amount of intervention received (dose) and the resulting outcome (response) to determine causality. It's valuable for confirming whether the intervention's intensity correlates with the observed impact.

When to Use

Use this method when you have quantitative data on both the intervention's dosage and the outcomes to statistically analyze their correlation.

How It Works

Solves: Unclear causal link, difficulty proving impact.

Step-by-Step Instructions
Follow these steps to facilitate this method
  1. 1

    Step 1: Gather data on intervention dosage and outcomes (30 min).

  2. 2

    Step 2: Create scatter plots to visualize the relationship (30 min).

  3. 3

    Step 3: Perform regression analysis to quantify the dose-response relationship (60 min).

  4. 4

    Step 4: Interpret the results and draw conclusions about causality (30 min).

Facilitator Tips
  • Control for confounding variables that may influence the outcome.
  • Consider non-linear relationships between dose and response.
Variations
  • Qualitative dose-response assessment using case studies
