| Hours | Number of Students |

| 0-5 | 8 |

| 6-10 | 12 |

| 11-15 | 20 |

| 16-20 | 10 |

Calculate the mean study hours.

**Options:**

a) 10.5

b) 11.5

c) 12.5

d) 13.5

**Solution:**

First, ﬁnd the midpoints of each class interval:

0-5 → 2.5

6-10 → 8

11-15 → 13

16-20 → 18

Multiply midpoints by frequency:

2.5 × 8 = 20

8 × 12 = 96

13 × 20 = 260

18 × 10 = 180

Sum of (midpoint × frequency) = 20 + 96 + 260 + 180 = 556

Total number of students = 8 + 12 + 20 + 10 = 50

Mean = 556 / 50 = 11.12 (approximately 11.5)

**Correct answer:** b) 11.5

This example highlights how solving MCQs can reinforce the method of calculating means

for grouped data.

Example 2: Understanding Correlation Coeﬃcient

**Question:** If the correlation coeﬃcient between two variables X and Y is -0.85, what

does it imply?

**Options:**

a) Strong positive correlation

b) Weak positive correlation

c) Strong negative correlation

d) No correlation

**Solution:**

The correlation coeﬃcient ranges between -1 and +1. A value of -0.85 indicates a strong

negative correlation, meaning as X increases, Y tends to decrease signiﬁcantly.

**Correct answer:** c) Strong negative correlation

This MCQ helps students quickly interpret statistical measures and their implications in

data analysis.
