Practice Questions

Q1. Which item is part of the RBSE syllabus line for this topic?

A Standard deviation
B Tally marks Correct
C Regression equation
D Sampling error formula

Explanation

Tally marks are explicitly inside the verified RBSE syllabus excerpt, along with frequency distribution tables and graphs. The other options are higher-level statistics items outside this note.

Q2. Match the tool with the best use: 1. Mean 2. Mode 3. Histogram. Which pairing is correct?

A 1-most common, 2-middle, 3-category names
B 1-middle, 2-fair share, 3-parts of whole
C 1-parts of whole, 2-intervals, 3-most common
D 1-fair share, 2-most common, 3-grouped intervals Correct

Explanation

Mean is the fair-share average, mode is the most common value, and a histogram represents grouped numerical intervals. The item checks whether the learner keeps summaries and graphs separate.

Q3. A learner draws a neat bar graph but leaves out the scale on the vertical axis. What is the best teacher response?

A Ask the learner to add a scale and explain what one unit represents Correct
B Give full credit because the bars look equal
C Change the graph into a pie chart immediately
D Ignore the axis because labels are enough

Explanation

The teacher should keep the correct graph choice but repair the missing scale. Asha-type mistakes need prompts about one unit, axis labels and frequency reading, not punishment.

Q4. Farida wants to show parts of one complete class preference survey. Which representation can show parts of a whole?

A Frequency table only
B Line graph
C Circular graph Correct
D Unsorted raw list

Explanation

A circular graph is appropriate when the categories together form one whole. Farida must first ensure the survey categories exhaust the class responses, then convert them into sectors.

Q5. Assertion: A class survey of 20 students should not be used to claim that all Rajasthan students prefer the same sport. Reason: A conclusion must match the data source and sample size.

A Both are true, and the reason explains the assertion Correct
B Both are true, but the reason does not explain the assertion
C Assertion is true, reason is false
D Assertion is false, reason is true

Explanation

The assertion and reason are both true. The class survey tells us about those 20 learners only; extending it to all Rajasthan students ignores source, sample size and survey boundary.
