SUMMARY

The discussion centers on the concept of mode in a dataset where all values are unique. It is established that if all data values are different, the dataset does not possess a mode. The conversation also clarifies the distinction between Probability Density Function (PDF) and Probability Distribution Function, emphasizing that the former is typically used for continuous data. The inference regarding the PDF in cases of unique datasets is that it corresponds to a probability function, which assigns probabilities to finite outcomes.

PREREQUISITES
  • Understanding of Probability Density Function (PDF)
  • Knowledge of Probability Distribution Function
  • Familiarity with statistical concepts such as mean and median
  • Basic principles of data uniqueness in statistical analysis
NEXT STEPS
  • Research the differences between Probability Density Function and Probability Distribution Function
  • Explore statistical implications of unique datasets on measures of central tendency
  • Learn about how to visualize unique data distributions using statistical software
  • Investigate the application of PDFs in real-world data analysis scenarios
USEFUL FOR

Statisticians, data analysts, and anyone interested in understanding the implications of unique datasets on statistical measures and probability functions.

Question is what is the mode when all data are unique? have a set wherein the actual question is what is the inference about the PDF for the data? Median > mean but no mode...i was under the impression that PDF is only for a continuous measurements...when data set is unique...in which case it should be a probability function & not PDF.

Please confirm...what is the mode and what if anything would the PDF look like in this case

The typical definition is that if all data values are different the data set does not have a mode.
I'm not sure what the rest of your question means - what kind of inference?
The abbreviation PDF is used for both of the following:
  1. Probability density function (most common)
  2. Probability distribution function (less common, but still done)

To which are you referring?
 
If you have a distribution with a finite number of outcomes, each assigned a probability (which, of course, sums to 1), then that function (which, I think, is what you are calling the "probability function") is or at least corresponds to the PDF. It might be clearer if you were to show the entire problem.
