📐 How It Works

Finds the most frequently occurring value(s) in a data set. A data set may be unimodal (one mode), bimodal (two modes), or multimodal.

🔢 Worked Examples

• [1, 2, 2, 3, 4] → Mode = 2
• [1, 1, 2, 2, 3] → Bimodal: 1 and 2
• [1, 2, 3, 4] → No mode (all equal frequency)
• Survey: red(10), blue(15), green(8) → Mode = blue

📋 Common Use Cases

• Most popular product size or colour in retail
• Most frequent error code in system logs
• Shoe size stocking decisions
• Survey response analysis

💡 Did You Know?

The mode is the only average that makes sense for categorical data — you can ask "what is the most common eye colour?" but not "what is the mean eye colour?"

⚠️ Common Mistake

Stating there is no mode when every value appears once — technically any set where all values occur equally is "no mode" or "all modes," depending on convention.
