# Introduction to Data Segment Analytics

## Overview

When running an A/B Test, you can obtain data analysis results collected from all test subjects.\
Hackle provides a way to analyze data in more detail based on these results.

For example, the following types of analyses are possible:

* Analysis by platform used by users (PC web, Mobile web, Mobile App)
* Analysis by OS used by users (Windows, Mac, Android, Linux)
* Analysis by app version used by users
* Analysis by user membership tier

## Preparing for Detailed Analysis

The following steps are required for detailed analysis:

1. **Define Segment Criteria**
   * Segment Criteria refers to the subject of the detailed analysis, which can be thought of as a grouping of entities with similar characteristics or within a defined range.
   * For example, if the goal is "to analyze by OS used by the user," the Segment Criteria would be **OS**.
2. **Define Segment Items**
   * The items selected for analysis from among the values that the Segment Criteria can have.
   * For example, if OS is selected as the Segment Criteria, the Segment Items can include Android, iOS, Windows, MacOS, etc.
3. **Collect Data**
   * Define properties (Property) matching the Segment Criteria and Segment Items.
   * Collect data to analyze through property collection. Hackle SDK integration is required for data collection.
