Data is a group of numbers compiled to provide information.
Recording Data: Data can be gathered from a variety of sources.
Data is represented as pictures of items in a pictograph. It allows you to quickly answer the queries about the data.
A Pictograph expresses data as images, things, or pieces of objects. We've also learned how to interpret a pictogram and respond to the accompanying questions.
Bar Graph: A pictorial representation of numerical data made up of equal-width bars (rectangles) of various heights.
Data, as we've seen, is a collection of numbers gathered to provide information. To quickly extract a specific piece of information from a set of data, the data can be organised in a tabular manner using tally marks.
We've learnt about how to use a bar diagram or a bar graph to depict data. In a bar graph, horizontal or vertical bars of uniform width are drawn with equal space between them. Each bar's length provides the necessary information.
We've also learnt about how to choose a scale for the graph as part of this. One unit, for example, equals 100 pupils. We've also gone over how to read a bar graph. We've seen how different meanings can be made from the same.

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.
