NCERT class 7 mathematics chapter 3 – “Data Handling” teaches us that the collection, recording and presentation of data help us organise our experiences and draw inferences from them. For the CBSE exams, practice multiple-choice questions (MCQs) to prepare for the objective questions. We have provided Class 7 MCQ Questions on “Data and Handling” paired with comprehensive explanations. CBSE is emphasizing the role of MCQs as they assist in understanding the concepts completely.
As compared to subjective questions, MCQs are very different so practicing and understanding how to get appropriate answers in MCQs is very essential. To revise the main concepts, students should practice all the MCQs with the answers given. This will also help them familiarize themselves with the kinds of questions that might appear in the board exams.

Summary for NCERT class 7 mathematics chapter 3 – “Data Handling”
- The collection, recording and presentation of data help us organise our experiences and draw inferences from them.
- Before collecting data we need to know what we would use it for.
- The data that is collected needs to be organised in a proper table, so that it becomes easy to understand and interpret.
- Average is a number that represents or shows the central tendency of a group of observations or data.
- Arithmetic mean is one of the representative values of data.
- Mode is another form of central tendency or representative value. The mode of a set of observations is the observation that occurs most often.
- Median is also a form of representative value. It refers to the value which lies in the middle of the data with half of the observations above it and the other half below it.
- A bar graph is a representation of numbers using bars of uniform widths.
- Double bar graphs help to compare two collections of data at a glance.
- There are situations in our life, that are certain to happen, some that are impossible and some that may or may not happen. The situation that may or may not happen has a chance of happening.
