VALIDATION DATA INPUT

Enter Validation Data

Input your validation results to calculate inter-rater reliability and agreement metrics

📊 Basic Validation Metrics

Minimum recommended: 30 responses for statistical validity

Number of responses where AI and human coder assigned the same primary code

Responses AI flagged as uncertain or requiring human review

Total number of responses in your complete dataset

📈 Cohen's Kappa Calculation (Optional)

For more rigorous reliability assessment, enter your confusion matrix data. Leave blank for simple agreement rate only.

💡 Confusion Matrix: Enter the number of codes in your codebook, then input how many times each code was assigned by AI vs Human

Enter 2-20 codes (enter only if you want Cohen's Kappa)

⏱️ Time Efficiency Analysis (Optional)

📚 Validation Best Practices

✅ Achieve Target Agreement Rate

Aim for >85% agreement rate on validation samples. If below 80%, review codebook clarity and refine definitions. For Cohen's Kappa, target >0.70 for substantial agreement.

✅ Validate Adequate Sample Size

Minimum 30 responses for statistical validity. Validate 20% of high-confidence cases and 100% of flagged cases. Include stratified sampling across all codes.

✅ Document Error Patterns

Track systematic errors (codebook ambiguity, missed nuance, context blindness). Use findings to improve codebook definitions and AI prompts iteratively.

⚠️ Watch for Red Flags

  • Flag rate >25% suggests overly conservative AI settings
  • Low agreement on specific codes indicates poor definitions
  • Inconsistent human coding requires additional training

Understanding Validation Metrics

Agreement Rate: Simple percentage of cases where AI and human coders agreed. Target: >85%

Cohen's Kappa: Accounts for agreement by chance. Interpretation: <0.40 (Poor), 0.40-0.59 (Fair), 0.60-0.74 (Good), >0.75 (Excellent)

Flag Rate: Percentage of responses AI marks as uncertain. Target: <25% for efficient workflow
