डेटा साक्षरता की मूल बातें और इसका महत्व
In this Class 9 Artificial Intelligence topic from the Data Literacy chapter, students learn what data is, how it is collected, organised, represented and interpreted, and why reliable data matters. They explore the difference between facts and opinions, recognise patterns, consider data quality and bias, and understand how data supports informed decisions. The topic also builds awareness of responsible data use, privacy and the role of evidence in everyday life and AI systems.

Up to 9 questions from this page. Select your focus, then start.
Data provides examples from which an AI or machine-learning model can identify patterns and relationships. After training, the model may use those patterns to classify new inputs or make predictions. Screen colour, internet speed, and physical hardware are separate concerns and do not describe the main role of data in AI.
Machine-learning systems learn relationships and patterns from examples or data. Correct and relevant data gives the model information connected to the task, allowing it to learn useful relationships and produce better outputs. Attractive colours or a large room do not provide learning evidence, and decisions without examples do not support data-based learning.
Good data is generally accurate, relevant, sufficiently complete, and appropriate for the task. It gives the model a stronger basis for learning useful patterns, so its outputs may become more reliable. Good data does not mean every result will be identical or perfect, and bias does not automatically disappear; fairness still requires deliberate examination.
Row and column headings provide the context needed to interpret a table correctly. They identify the categories, items, dates, units, or measurements connected with each value. Thus, option C is correct because headings explain what every number represents and make comparison meaningful. They are not decoration, do not hide data, and do not convert a table into a picture.
Information is data that has been collected, organised, processed or interpreted so that it conveys meaning and can support understanding or a decision. For example, separate marks are raw data, while a calculated total, average or result is useful information. Therefore, option B is correct. Option A defines raw data, while options C and D are unrelated descriptions and cannot represent the general concept of information.
The governing concept is the difference between raw data and processed information. Each individual sale entry, such as an item, quantity, or price, is an original fact supplied to the computer before calculation. Therefore, option A, data, is correct. The daily total is processed information, not an output device or a network. Calling the entries final information would confuse the initial inputs with the meaningful result produced after processing.
The governing concept is that data becomes information after meaningful processing. The separate sales entries are added together, and the resulting daily total answers a useful business question. Hence option A, information, is correct. Raw data refers to the original individual entries before calculation. An input device is hardware used to enter data, while a network connects systems; neither describes the calculated total itself.
The correct answer is D. Data means facts, figures, symbols, measurements, or observations that can be entered into and processed by a computer. Before processing, data may be raw and not yet meaningful; after organization and interpretation, it can become useful information. Computer size, hardware colour, and electricity amount may be attributes or measurements, but they are not the general definition of data.
The governing concept is information processing. Raw data becomes information when it is organised, analysed, or processed so that it has meaning and can support understanding or decisions. Hardware is the physical equipment, and software is the set of programs that directs the equipment; neither term means processed data. Therefore, the standard answer to processed and useful data is information, so option D is correct.
