Class 10 Statistics Important Questions

Mean Questions Class 10

Q1. The marks obtained by 40 students in a class test are given below. Find the mean marks.

| Marks | 0–10 | 10–20 | 20–30 | 30–40 | 40–50 | 50–60 | 60–70 | 70–80 |
|------------|-------|-------|-------|-------|-------|-------|-------|
| No. of Students | 5 | 7 | 10 | 8 | 6 | 2 | 2 |

Solution:
Here we apply the step-deviation method.

• Class size (h) = 10
• Assume A = 35 (mid-value near middle).

• Calculate mean using formula:

$$\text{Mean} = A + \frac{\Sigma f d}{\Sigma f} \times h$$

After calculation, Mean = 33.5 marks.

Median Question Class 10

Q2. The following table represents the daily wages of workers. Find the median.

| Daily Wages (₹) | 0–50 | 50–100 | 100–150 | 150–200 | 200–250 |
|-----------------|--------|---------|----------|----------|
| No. of Workers | 5 | 10 | 20 | 15 | 10 |

Solution:
Steps:

1. Find cumulative frequency (CF).
2. Locate median class = the class interval containing $\frac{N}{2}$.

3. Apply formula:

$$\text{Median} = l + \left( \frac{\frac{N}{2} - CF}{f} \right) \times h$$

Result: Median = ₹137.5.

Mode Questions Class 10

Q3. Find the mode of the marks distribution.

| Marks | 0–10 | 10–20 | 20–30 | 30–40 | 40–50 |
|------------|-------|-------|-------|-------|
| No. of Students | 3 | 7 | 12 | 8 | 5 |

Solution:
Formula for mode:

Here, modal class = 20–30.
Mode = 25.
