4/5th Rule Formula:
| From: | To: |
The 4/5th Rule (also known as the 80% rule) is a guideline used in employment practices to determine if there is adverse impact in selection processes. It helps identify potential discrimination by comparing selection rates between different demographic groups.
The calculator uses the 4/5th rule formula:
Where:
Interpretation: If the ratio is less than 0.8 (4/5), adverse impact is indicated, suggesting potential discrimination in the selection process.
Details: Adverse impact analysis is crucial for ensuring fair employment practices, complying with equal opportunity regulations, and maintaining diversity in hiring and promotion processes.
Tips: Enter selection rates as percentages (0-100%) for both minority and majority groups. The calculator will compute the ratio and determine if adverse impact exists based on the 4/5th rule threshold.
Q1: What constitutes adverse impact under the 4/5th rule?
A: Adverse impact exists when the selection rate for any minority group is less than 80% of the rate for the majority group.
Q2: Is the 4/5th rule a legal requirement?
A: While not a strict legal standard, it's a widely accepted guideline used by the Equal Employment Opportunity Commission (EEOC) to identify potential discrimination.
Q3: What types of selection processes does this apply to?
A: The rule applies to hiring, promotion, training opportunities, and any other employment decisions where selection rates can be compared between groups.
Q4: What should I do if adverse impact is detected?
A: Further investigation is needed to determine if the selection process is job-related and consistent with business necessity, or if alternative selection methods should be considered.
Q5: Are there limitations to the 4/5th rule?
A: Yes, it's a rule of thumb and doesn't account for statistical significance. Small sample sizes may produce misleading results, and additional statistical tests may be needed for conclusive analysis.
