1. What Is Adverse Impact Ratio?

The Adverse Impact Ratio, also known as the Four-Fifths Rule or 80% Rule, is a statistical measure used in employment practices to identify potential discrimination. It compares the selection rates of minority and majority groups to determine if there is disparate impact.

2. How Does The Calculator Work?

The calculator uses the Adverse Impact Ratio formula:

\[ Ratio = \frac{Minority\ Selection\ Rate}{Majority\ Selection\ Rate} \]

Where:

EEO 80% Rule: If the ratio is less than 0.8 (80%), adverse impact is indicated, suggesting potential discrimination that requires further investigation.

3. Importance Of Adverse Impact Analysis

Details: Adverse impact analysis is crucial for ensuring fair employment practices, complying with Equal Employment Opportunity (EEO) regulations, and promoting diversity and inclusion in the workplace.

4. Using The Calculator

Tips: Enter the selection rates for both minority and majority groups as percentages (0-100%). The calculator will compute the ratio and determine if adverse impact exists based on the 80% rule.

5. Frequently Asked Questions (FAQ)

Q1: What is the legal significance of the 80% rule?
A: The 80% rule is a guideline used by the Equal Employment Opportunity Commission (EEOC) to identify potential discrimination. While not definitive proof, it triggers the need for further investigation.

Q2: What selection rates should be used?
A: Use the percentage of applicants from each group who were selected for hiring, promotion, or other employment opportunities.

Q3: Is adverse impact always illegal?
A: Not necessarily. If an employer can demonstrate that the practice is job-related and consistent with business necessity, it may be justified despite adverse impact.

Q4: What sample size is needed for reliable analysis?
A: Larger sample sizes provide more reliable results. Small sample sizes may produce misleading ratios due to statistical variability.

Q5: Should this analysis be conducted regularly?
A: Yes, regular monitoring of selection processes helps organizations identify and address potential discrimination proactively.
