Association and correlation are two terms used commonly in the correlational studies. What is the basic difference between these two terminology?
correlation is a special association where variables have a linear relationship. In some context association is a concept while correlations are particular mathematical measurements.
Association is related to commonness between attributes and correlation is commenness between variables
All of the above are true. I would add though that the terms are commonly used interchangeably in scientific writing to reduce repetition.
Association is concept its used when relationship between two random variables makes this variables statistically dependent. for example smoker and lung cancer so its refer to general relationship between two random variables while the correlation refers to a more or less a linear relationship between the random variables
