Find the Mean of this data set:

💡 How to Calculate

📊 Mean (Average)

Add all values, then divide by how many there are.

Mean = Sum ÷ Count

e.g. (2+4+6+8+10) ÷ 5 = 30 ÷ 5 = 6

📈 Median (Middle)

Sort the values, then find the middle one.

Middle value when sorted

e.g. 2, 4, 6, 8, 10 → Median = 6

🔢 Mode (Most common)

The value that appears most often.

Most frequent value

e.g. 2, 4, 4, 8, 10 → Mode = 4

↔️ Range (Spread)

Largest value minus smallest value.

Range = Max − Min

e.g. 2, 4, 6, 8, 10 → 10 − 2 = 8
