Assertion Reason Questions
Directions:
Each of the following questions consists of two statements: an Assertion (A) and a Reason (R). Answer them by selecting the correct option:
(a) Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
(b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(c) Assertion (A) is true, but Reason (R) is false.
(d) Assertion (A) is false, but Reason (R) is true.
Q1. Assertion (A): The mean of a data set is affected by extreme values.
Reason (R): Mean is the average of all values and gives equal weight to each.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Difficulty Level: Moderate
Q2. Assertion (A): The median is always equal to the mean for every data set.
Reason (R): Median divides the data into two equal parts.
Answer: (c) Assertion is false, but Reason is true.
Difficulty Level: Moderate
Q3. Assertion (A): In a frequency distribution, the mode is the value of the class with the highest frequency.
Reason (R): Mode is the value that occurs most frequently in a data set.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Difficulty Level: Moderate
Q4. Assertion (A): If all the observations in a data set are equal, then the mean, median, and mode are different.
Reason (R): These measures depend on the shape of the distribution.
Answer: (d) A is false, but R is true.
Difficulty Level: Tough
Q5.
Assertion (A): The empirical formula for mode is
$$
\text { Mode }=3 \times \text { Median }-2 \times \text { Mean }
$$
Reason (R): This formula is used only when the frequency distribution is symmetrical.
Answer: (b) Both A and $R$ are true, but $R$ is not the correct explanation of $A$.
Difficulty Level: Tough
