what is the meaning of a relative frequency of 1?

The relative frequency of 1 refers to a situation where an event or category occurs with a frequency that is equal to the total number of observations or occurrences in a dataset. In other words, it means that the event or category in question is observed or occurs every time.

To determine the relative frequency, you need to know the total number of observations or occurrences in your dataset and the number of times the specific event or category of interest occurs. Once you have this information, you can calculate the relative frequency using the following formula:

Relative Frequency = (Number of occurrences of the event or category) / (Total number of observations or occurrences)

If the resulting relative frequency is 1, it means that the event or category of interest occurs every time or is observed in every instance.
