A frequency distribution table is a tool used to organize and summarize data, showing how often each value or interval appears in a dataset. It typically includes two columns:

• Classes/Categories: Data groups or intervals.

• Frequency: Number of occurrences in each group.

Importance in Statistical Investigation:

• Simplifies data: Converts raw data into an organized format.

• Highlights patterns: Helps identify trends and outliers.

• Aids analysis: Supports calculation of mean, median, mode, etc.

• Improves interpretation: Makes data easier to understand and compare.

• Supports graphical representation: Forms the basis for charts like histograms.
