Q1.
Assertion (A): A bar graph is a graphical representation of data using bars of equal width.
Reason (R): The height of the bar represents the frequency of the data.
Option: ___
Q2.
Assertion (A): Pictographs are useful for representing large numerical data using pictures or symbols.
Reason (R): One symbol can represent multiple units of data.
Option: ___
Q3.
Assertion (A): The tally mark "||||" represents the number 4.
Reason (R): A set of 5 is shown as "|||||".
Option: ___
Q4.
Assertion (A): It is necessary to draw bars with equal width in a bar graph.
Reason (R): Unequal widths can mislead data interpretation.
Option: ___
Q5.
Assertion (A): Data handling is useful only in Mathematics.
Reason (R): Other subjects do not require graphical data representation.
Option: ___
Q6.
Assertion (A): In a bar graph, the bars can be drawn either vertically or horizontally.
Reason (R): The direction of the bar doesn't affect the data value.
Option: ___
Q7.
Assertion (A): Tally marks help in quickly counting and organizing data.
Reason (R): Tally marks group data in sets of 5 for convenience.
Option: ___
Q8.
Assertion (A): All bars in a bar graph must be drawn touching each other.
Reason (R): Gaps between bars create confusion.
Option: ___
Q9.
Assertion (A): A bar graph is more precise than a pictograph.
Reason (R): Bar graphs allow accurate reading of exact values.
Option: ___
Q10.
Assertion (A): Data is a collection of facts or information.
Reason (R): Information can be in the form of numbers, words, or measurements.
Option: ___
Q11.
Assertion (A): In a pictograph, each symbol must represent the same number throughout the graph.
Reason (R): Changing the value of the symbol mid-graph makes it hard to interpret.
Option: ___
Q12.
Assertion (A): A frequency table tells us how often each item appears in data.
Reason (R): It helps to identify the most or least frequent items.
Option: ___
Q13.
Assertion (A): When using pictographs, symbols can represent decimal numbers.
Reason (R): Each symbol must only represent whole numbers.
Option: ___
Q14.
Assertion (A): Data handling does not include drawing graphs.
Reason (R): Graphs are only part of drawing, not mathematics.
Option: ___
Q15.
Assertion (A): The scale of a bar graph can affect how tall or short the bars look.
Reason (R): The vertical axis determines the frequency values.
Option: ___
Q16.
Assertion (A): A title is not required in a bar graph.
Reason (R): The bars themselves show everything.
Option: ___
Q17.
Assertion (A): Double bar graphs can be used to compare two sets of data.
Reason (R): They allow visual comparison between two categories.
Option: ___
Q18.
Assertion (A): Before creating a graph, it is important to organize the data.
Reason (R): Organized data ensures better accuracy and easier representation.
Option: ___
Q19.
Assertion (A): A bar graph can help detect trends or patterns in data.
Reason (R): Graphs allow easy visual interpretation.
Option: ___
Q20.
Assertion (A): Data handling includes collecting, organizing, and interpreting data.
Reason (R): It helps in making decisions based on data.
Option: ___
