3. What is data handling?

Data handling is a branch of mathematics that deals with the collection, storage, and representation of important data. This data could be marks of students, scores in a game, weights of people, or any other such statistic. This allows for easy inferences from the data for research purposes. Chapter 9 "Data Handling" teaches Class 6 students the basics of data handling through various means like tally marks, pictographs, and drawing and interpretation of bar graphs.

4. How do you do data handling?

As we have studied, data handling is the assembling, recording, and displaying of various types of data to draw different conclusions based on it. There are several ways by which data can be represented efficiently:

Making a tally chart

Using a pictograph

Using a bar graph

These are the main methods taught in Chapter 9. Several other methods of data handling exist like pie charts, line graphs, histograms, stem and leaf plots, etc.

5. What is recording data?

The most important aspect of data handling is the recording of the data. This refers to gathering the required data and then meticulously recording it to make inferences later. This step requires precision and accuracy on the part of the one who records the data. Any mistake in this step leads to inaccurate statistics. Students can refer to Vedantu's notes and explanation on this chapter for further understanding of the important concepts of Chapter 9. If you want to understand these concepts more accurately then use the revision notes available on Vedantu.

6. What are the types of data handling?

The various types of data handling means mentioned in Chapter 9 are as follows:

Tally mark chart: Using tally marks requires a table chart in which one column represents the type of data being collected and the next column represents the tally marks for easy record of large quantities.

Pictographs: These represent the data in the form of simple images for easy inferences.

Bar Graphs: They represent data using rectangular bars denoting different values.

7. How do you draw a pictograph?

Pictograms use various pictures to represent the data. To make an accurate pictograph:

Choose an image relevant to your data.

Make a table. In one column mention the category being represented. In the second column draw the symbolic data for each category.

Note that these images can represent larger quantities.

Do not forget to mention the key of these images below the pictograph so that the information can be easily understood.
