FREQUENCY DISTRIBUTION
The main purpose of a frequency distribution is to organize raw data (b).
A frequency distribution is a tabular summary of data that shows the frequency, or number of occurrences, of different values within a dataset. It is used to organize and analyze large amounts of data in a clear and concise manner.
For example, if you were conducting a survey to gather data on the number of hours that people work per week, you could use a frequency distribution to organize the data and see how many people work different ranges of hours (e.g., 0-10 hours, 11-20 hours, 21-30 hours, etc.).
Option a, planning a statistical project and assigning tasks to workers, is not the main purpose of a frequency distribution.
Option c, providing a graphical illustration of data relations, is not an accurate description of a frequency distribution.
Option d, identifying changing trends over time, is not the main purpose of a frequency distribution, but it can be used to identify trends if the frequency distribution is created for different time periods.
