## Key Metrics

### Experiment Results
- `variation_id` - Variation identifier
- `variation_name` - Variation display name
- `visitors` - Unique visitors per variation
- `conversions` - Conversion count
- `conversion_rate` - Rate as decimal
- `improvement` - Percentage improvement vs. control
- `statistical_significance` - Confidence level
- `is_baseline` - Whether this is the control

### Experiment Properties
- `name` - Experiment name
- `status` - not_started, running, paused, archived
- `type` - a/b, multivariate, personalization
- `traffic_allocation` - Percentage of traffic (0-10000 = 0-100%)
- `variations` - Array of variations with weights

## Parameters

### List Experiments
- `project_id` (required) - Project to list experiments for
- `page` - Page number
- `per_page` - Results per page (default: 25)
- `status` - Filter by status

### Get Results
- `start_time` - Results start time (ISO 8601)
- `end_time` - Results end time (ISO 8601)

### Create Experiment
- `project_id` (required) - Parent project
- `name` (required) - Experiment name
- `type` - Experiment type (default: a/b)
- `variations` (required) - Array of variations with name and weight
- `metrics` - Array of metric/event configurations
- `audience_conditions` - Targeting conditions
- `traffic_allocation` - Traffic percentage (0-10000)

## When to Use

- Running A/B tests on web pages and features
- Managing experimentation programs at scale
