Multiple Choice Questions

Q1: What does data handling mean?
(a) Collecting and presenting data in different forms
(b) Analyzing and interpreting data
(c) Storing and securing data
(d) Creating graphs and charts
Ans: (a)
Data handling refers to the process of collecting data and presenting it in various forms such as tables, graphs, or charts.

Q2: Which of the following is an example of qualitative data?
(a) Height of students in a class
(b) Number of books in a library
(c) Types of fruits in a basket
(d) Temperature readings over a week
Ans: (c)
Qualitative data provides descriptive information and can include categories or types, such as the different types of fruits in a basket.

Q3: Discrete data can take which of the following values?
(a) Any real number
(b) Only whole numbers
(c) Numbers within a range
(d) Both whole numbers and decimal numbers
Ans: (b)
Discrete data consists of distinct values and can only take certain values, typically whole numbers, and not decimal or fractional values.

Q4: What is the fourth step in the data handling process?
(a) Problem Identification
(b) Data Collection
(c) Data Presentation
(d) Graphical Representation
Ans: (c)
After collecting data, the next step is to present it in a meaningful manner so that it can be easily understood and analyzed.

Q5: Which of the following is a graphical representation of data?
(a) Frequency Distribution
(b) Cumulative Tables
(c) Stem and Leaf Plot
(d) Pictographs

Ans: (d)
Pictographs are graphical representations of data using pictures or symbols to represent quantities or categories.

Short Questions

Q1: Define qualitative data and provide an example.

Ans: Qualitative data provides descriptive information about something. For example, the colors of cars in a parking lot or the types of animals in a zoo are examples of qualitative data.


Q2: Explain the steps involved in the data handling process.

Ans: The steps involved in the data handling process are as follows:

  • Problem Identification: Clearly define the purpose or problem statement.
  • Data Collection: Gather relevant data related to the problem statement.
  • Data Presentation: Organize and present the collected data in a meaningful way, such as through tables or graphs.
  • Graphical Representation: Create visual representations of the data using graphs, charts, or diagrams.
  • Data Analysis: Analyze the data to draw conclusions, identify patterns, or make comparisons.
  • Conclusion: Based on the analysis, derive a solution or draw meaningful insights from the data.


Q3: How can data be represented using a bar graph? Provide an example.
Ans: To represent data using a bar graph, follow these steps:

  • Identify the categories or variables to be represented on the graph.
  • Choose an appropriate scale for the axes (usually the x-axis represents the categories and the y-axis represents the values).
  • Draw bars of equal width for each category, with the height or length of the bars representing the corresponding values.
  • Label the axes and provide a title for the graph.


Q4: What is the difference between discrete data and continuous data?
Ans: Discrete data consists of distinct values that cannot be further divided. For example, the number of siblings a student has or the number of books on a shelf are discrete data. Continuous data, on the other hand, can take any value within a range. For example, the height or weight of a person can be continuous data as it can have decimal or fractional values.

Q5: Name three different methods to represent data.
Ans: Three different methods to represent data are:

  • Bar Graphs: These use rectangular bars of equal width to represent categories or variables, with the length of the bars proportional to the values.
  • Line Graphs: These use lines to show the relationship between two variables, typically with time represented on the x-axis.
  • Pictographs: These use pictures or symbols to represent quantities or categories, with each picture representing a specific value or quantity.
