Explanation:

Data presentation refers to the method of displaying data in a way that is understandable and easy to interpret. The three main modes of data presentation are textual, tabular and diagrammatic. Let's discuss each of these modes in detail.

1. Textual Presentation:
In this mode of presentation, data is presented in the form of paragraphs, sentences, and statements. This mode is useful when the data is limited and can be easily presented in a few lines. For example, a summary of a research article, or a news article. This mode is simple, easy to understand and requires no special skills to interpret.

2. Tabular Presentation:
In this mode of presentation, data is presented in the form of tables. This mode is useful when the data is extensive and requires a lot of information to be displayed. Tables are an excellent way of organizing the data, and it is easy to compare different values. Data can be presented in rows and columns, and it is easy to identify patterns and trends in the data.

3. Diagrammatic Presentation:
In this mode of presentation, data is presented in the form of diagrams, graphs, and charts. This mode is useful when the data needs to be visualized to understand the relationships between different variables. Diagrams are an excellent way of presenting complex data in a simple and understandable manner. They help in identifying trends and patterns, and it is easy to compare different values.

Conclusion:
To summarize, the three main modes of data presentation are textual, tabular, and diagrammatic. Each mode has its advantages and disadvantages, and the choice of mode depends on the nature and complexity of the data.
