My question is related to this one: Differences between “methods”, “methodologies” and “paradigms”

In lectures, we learned

In statistical practice, there are two main schools of thought or paradigms:

  1. frequentist
  2. Bayesian

Moreover, on the shelf we have books with titles like Decision Analysis: A Bayesian Approach or Machine Learning: A Bayesian and Optimization Perspective

I was wondering what are the differences between Approach, Perspective, and Paradigms?

  • 1
    Approach is more action-oriented that perspective which is like a view point. E.g., He approaches the problems differently. His thoughts/ view points/ perspectives are different. Paradigm is usually heard in management studies.

"Approach" implies a hands-on style. "Perspective" is more theoretical. "Paradigm" is similar to perspective, but implies that some specific model will be used, i.e., it will be a "systematic" perspective.

  • What's your approach to saving money? (How do you do it?)
  • What's your perspective on saving money? (How do you look at it?)
  • What's your money saving paradigm? (What's the actual model?)

Sometimes these three terms are used interchangeably.
