Ever wonder why your favorite group moved up or down? The institute follows a strict four-step data analysis process to ensure accuracy:

**Step 1: Data Collection & Consumer Participation**  
The institute gathers millions of data points, focusing on “Participation.” This measures how often fans search for the group or click on news related to them. High search volume usually leads to a higher rank.

**Step 2: Media Index Analysis**  
This step tracks how much the group is featured in news articles, broadcast appearances, and magazine shoots. A group with a recent comeback, like BABYMONSTER, usually sees a massive spike here.

**Step 3: Communication & Social Buzz**  
This measures the “talkability” of the group on social platforms like X, TikTok, and Instagram. Viral dance challenges and trending hashtags are the lifeblood of this specific index.

**Step 4: Community Perception**  
The final step uses “Sentiment Analysis.” It looks at whether the public conversation around the group is positive or negative. Keywords like “record-breaking,” “powerful,” and “charming” often boost the total score.
