The following Assertion and Reason questions are based on Chapter 13: Connecting the Dots from the NCERT Class 7 Mathematics textbook. Each question has four options - read both the Assertion (A) and Reason (R) carefully before selecting your answer.
How to attempt Assertion & Reason questions:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is NOT the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is NOT the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Assertion & Reason Questions
1
Assertion (A): A statistical question anticipates variability in its answers.
Reason (R): It is usually answered by collecting data from multiple observations.
Reason (R): It is usually answered by collecting data from multiple observations.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Variation makes data analysis necessary.
2
Assertion (A): A statement about a group may require representative data.
Reason (R): A single unusual case can be misleading.
Reason (R): A single unusual case can be misleading.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but the warning is an example rather than a complete sampling principle.
3
Assertion (A): It has one fixed mathematical answer.
Reason (R): The question 'What is 2+3?' is statistical.
Reason (R): The question 'What is 2+3?' is statistical.
Answer: (c)
A is true, but R is false. No data variability is expected.
4
Assertion (A): Every claim based on data is automatically reliable.
Reason (R): Reliability depends on data quality, method and interpretation.
Reason (R): Reliability depends on data quality, method and interpretation.
Answer: (d)
A is false, but R is true. Evidence must be examined.
5
Assertion (A): The mean is the sum of values divided by their count.
Reason (R): It represents an equal-share balance point.
Reason (R): It represents an equal-share balance point.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Redistributing the total equally gives the mean.
6
Assertion (A): The median is the middle ordered value.
Reason (R): The mode is the most frequent value.
Reason (R): The mode is the most frequent value.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true definitions, but mode does not explain median.
7
Assertion (A): The mean of 2, 4 and 9 is 5.
Reason (R): The sum of these values is 14.
Reason (R): The sum of these values is 14.
Answer: (c)
A is true, but R is false. Their sum is 15, and 15 divided by 3 is 5.
8
Assertion (A): The median of 1,3,8,10 is 8.
Reason (R): For an even count, the two middle values are averaged.
Reason (R): For an even count, the two middle values are averaged.
Answer: (d)
A is false, but R is true. The median is (3+8)/2 = 5.5.
9
Assertion (A): An extreme value can pull the mean toward it.
Reason (R): The extreme changes the total used in the mean.
Reason (R): The extreme changes the total used in the mean.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Its large contribution shifts the average.
10
Assertion (A): The median is often more resistant to an outlier than the mean.
Reason (R): A bar graph compares category values visually.
Reason (R): A bar graph compares category values visually.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but graph type does not explain resistance.
11
Assertion (A): It summarises a distribution rather than reproducing all observations.
Reason (R): A representative value always describes every individual exactly.
Reason (R): A representative value always describes every individual exactly.
Answer: (c)
A is true, but R is false. Individuals can differ from the centre.
12
Assertion (A): The mode must be unique in every data set.
Reason (R): A data set can have more than one most frequent value or none uniquely.
Reason (R): A data set can have more than one most frequent value or none uniquely.
Answer: (d)
A is false, but R is true. Modes may tie.
13
Assertion (A): Bar lengths should be read using the labelled scale.
Reason (R): The scale converts visual length into data value.
Reason (R): The scale converts visual length into data value.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Ignoring it can cause a wrong reading.
14
Assertion (A): A line graph is useful for ordered change such as time.
Reason (R): A pictograph uses symbols to represent counts.
Reason (R): A pictograph uses symbols to represent counts.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but pictographs do not explain line graphs.
15
Assertion (A): Changing the displayed baseline can exaggerate apparent differences.
Reason (R): A truncated vertical axis can never affect visual interpretation.
Reason (R): A truncated vertical axis can never affect visual interpretation.
Answer: (c)
A is true, but R is false. Graph design influences perception.
16
Assertion (A): More data always remove every source of bias.
Reason (R): A large biased sample can still misrepresent the population.
Reason (R): A large biased sample can still misrepresent the population.
Answer: (d)
A is false, but R is true. Selection matters as well as size.
17
Assertion (A): A conclusion should match the data actually collected.
Reason (R): Claims extending beyond the sample require caution.
Reason (R): Claims extending beyond the sample require caution.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Evidence limits the justified inference.
18
Assertion (A): Frequency records how often a value occurs.
Reason (R): Cumulative frequency gives a running total.
Reason (R): Cumulative frequency gives a running total.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but cumulative totals do not define ordinary frequency.
19
Assertion (A): Different distributions can share the same mean.
Reason (R): Two data sets with the same mean must have identical values.
Reason (R): Two data sets with the same mean must have identical values.
Answer: (c)
A is true, but R is false. Centre alone does not determine the data.
20
Assertion (A): A graph without labels and units is fully interpretable.
Reason (R): Labels, scale and units give essential context.
Reason (R): Labels, scale and units give essential context.
Answer: (d)
A is false, but R is true. Without them the quantities are ambiguous.
