Summary – Grouping of Data
Grouping of data is a statistical technique used to organize and summarize large sets of data into smaller, more manageable groups or intervals. This process involves categorizing raw data into classes or intervals based on their values, with each group representing a range of values. Grouping facilitates easier interpretation and analysis of data by reducing complexity and highlighting important patterns or trends. Common methods of grouping include equal width intervals, equal frequency intervals, and percentile groups. Grouping of data is essential in descriptive statistics for constructing frequency distributions, histograms, and cumulative frequency curves, enabling researchers and analysts to draw meaningful insights and conclusions from the data.

- Pictograph
- Bar Graph
- Double Bar Graph
