Final answer:
The question about the distinction between 'PS' and 'SS' depends on the context as 'PS' is not a standard statistical abbreviation, whereas 'SS' often means Sum of Squares.
Step-by-step explanation:
When seeing the question What really distinguishes PS from SS, it looks to be a question comparing two different types of statistical values, 'PS' and 'SS', which are likely abbreviations. In the context of statistics, 'PS' is not a standard abbreviation, but 'SS' typically stands for Sum of Squares. But without further context, it is challenging to definitively specify what 'PS' refers to. It could potentially be 'Population Size', 'Parameter Space', 'Point Score', or any other statistical term depending on the specific context within the subject material. Therefore, without more clarity or context, providing a specific difference is not possible. It's important to verify the meaning of 'PS' within a given context before drawing a comparison with 'SS'.
