I need experiment result details in JSON structure.

Approach:
1. Task: Create experiment result in JSON
2. Complexity: simple - 3-5 fields, minimal nesting
3. Format rules: proper braces/brackets, quoted keys, correct value types
4. Structure: Organize data logically with appropriate nesting
5. Populate fields with realistic example data based on the schema.

Output:
{
  "methodology": {
    "design": "RCT",
    "sample_size": 193,
    "duration_days": 365
  },
  "experiment_id": "EXP-345048",
  "conclusion": "significant"
}
