Group Generator

How to Use

1. Enter Participants: Type or paste names (or items) one entry per line.
2. Choose Division Method: Select either **Number of Groups** or **People per Group**.
3. Set Parameters: Enter the desired number of groups (e.g., 5) or the group size (e.g., 4).
4. Select Sorting: Choose **Random** for unbiased teams, or **Alphabetical** to keep input order.
5. Generate: Click "Generate Groups" to randomly assign participants.
6. Review Results: Check the size distribution, especially for uneven totals.
7. Export: Use "Copy All Groups" or "Download as Text" to share the results.

Key Features

• Fair Distribution: Algorithm ensures groups are as evenly sized as possible.
• Two Division Modes: Split based on the total number of groups or the desired size of each group.
• Supports Any List: Works for names, student IDs, project items, or any line-separated text.
• Instant Shuffling: The Random Sort option ensures immediate, unbiased team formation.
• Results Export: Easily copy the final groups to your clipboard or download a text file.
• Free to Use: Generate unlimited teams for classrooms, meetings, and events.
• Quick Actions: Buttons to instantly add sample names or clear the list.
• Total Count: Real-time display of the number of participants entered.

Common Grouping Scenarios

Best Practices for Fair Grouping

• Use Randomization: Always select **Random Order** to prevent unintentional bias based on list entry order.
• **Handle Remainders:** If 21 people are split into groups of 5, the tool will create three groups of 5 and one group of 6. Be ready to communicate the slightly varied sizes.
• **Focus on Outcomes:** Define the group goal (e.g., skill balance, equal size) before setting parameters.
• **Copy Results:** Save the results immediately after generating, especially if you need to reference the same teams later.
• **Check Input:** Ensure every name is on its own line and that there are no blank lines or duplicate entries.

Mathematical Group Distribution

• **Total People ($N$):** The total number of entries in the list.
• **Number of Groups ($G$):** The target number of groups. The average size is $N / G$. The sizes will range between $\lfloor N/G \rfloor$ and $\lceil N/G \rceil$.
• **People Per Group ($P$):** The target group size. The total groups created will be $G = \lceil N / P \rceil$.
• **Remainder ($R$):** The number of people left over when dividing $N$ by $P$. This remainder is distributed among the first $R$ groups to ensure maximum evenness.
