## IMO class 5 chapter 7: Data Handling Detailed Notes

As it handles several crucial aspects including security, confidentiality, and the preservation of the research data, “Data Handling” is a crucial concept in statistics that assures the integrity of the research data. We have data in the form of numerical figures in every sector. Every such figure is regarded as an observation. Data is the general term used to describe the collection of all observations. Statisticians utilize a variety of data management techniques to handle the data. Let’s talk about data management and the several ways to handle data in this article.

### What is Data Handling?

The act of gathering a set of data and presenting it in a different format is known as data handling. A collection of numbers is referred to as data, and each number represents a certain type of information. The original collection of observations is referred to as raw data. Any kind of data is acceptable. Words, statistics, measurements, descriptions, or observations could all be included. Data management is the process of making sure that research data is collected, stored, or disposed of in a secure and safe manner both during and after the analytic process is complete.

### Types of data

Depending on the types of data, several data processing techniques can be used. The information is divided into two categories, including:

• Qualitative Data
• Quantitative Data

Quantitative data provides numerical information about something, whereas qualitative data provides descriptive information. Here, there are two further divisions of the quantitative data. Both discrete and continuous data are present. Only specific values, like whole numbers, are available for discrete data. The supplied range is the possible range for the continuous data.

### Steps in Data Handling

The following are the steps that make up the data handling process:

Step 1: Identifying the issue

The goal or problem statement must be clearly stated and established during the data handling process.

Step 2: Gathering Data

The information that relates to the problem statement is gathered.

Step 3: Data Presentation

The gathered information ought to be presented in a clear and understandable way. The data can be organized in table forms, tally marks, and other formats to do.

Step 4: Graphical Representation

The supplied data can be represented in graphs, or charts, such as bar graphs, pie graphs, and so on, since the visual or graphical representation of the data facilitates interpretation and understanding.

Step 5: Data Analysis

The data should be subjected to data analysis in order to draw the necessary conclusions from the data, which aids in taking additional actions.

Step 6: Conclusion

We can determine the answer to our problem statement by analyzing the data.

### How Can Data Be Represented?

Any of the following representations of the data is typically acceptable as follows:

• Bar Graph
• Line Graphs
• Pictographs
• Histograms
• Stem and Leaf Plot
• Dot Plots
• Frequency Distribution
• Cumulative Tables and Graphs

### How to Prepare for a Math Olympiad

Planning is especially important when an understudy is participating in a serious test, such as the International Math Olympiad. Maths Olympiad Workbooks and Previous Year Question Papers were provided by School Connect Online for students in grades 1 to 10. The subject specialists outline the review materials.
