For the data 2, 4, 4, 6, 9: which is correct about its mean, median, and mode?

Class 7Data HandlingData Handling
  • AMean = 5, median = 4, mode = 4
  • BMean = 4, median = 5, mode = 4
  • CMean = 5, median = 5, mode = 6
  • DMean = 4, median = 4, mode = 9

Step-by-Step Solution

Sum = 25, mean = 25/5 = 5. Sorted: 2, 4, 4, 6, 9 — middle value = 4. Mode = 4 (appears twice).
Answer: A) Mean = 5, median = 4, mode = 4

Key idea: When to use which

- **Mean**: when values are well-spread without extreme outliers (test scores, heights).
- **Median**: when there are extreme values (incomes, house prices) that would skew the mean.
- **Mode**: when you care about the most common value (most common shoe size, most popular subject).

In news headlines: 'average income' usually means mean (which can be misleading); 'median income' is often more honest.
