How much can the owner of a CPA firm make? I'm planning to get the CPA license and start my own small CPA firm. I want to hire bookkeepers and outsource the work overseas to save on overhead costs. I already have a large family of about 80 people, so I believe I can make at least 100 clients in my first year and do their taxes.
A correlation by definition, has no dependent and independent variable. It treats both variables equally. And each correlation is only about two variables. However, some people call observational studies correlational even if they use regressions. In a regression the independent variables are the ones you think predict or cause the dependent variable; or they are the ones under your control. Often the DV vs. IV distinction is one of substantive logic, not statistics.
An observational study is a study in which subjects are not randomized to the exposed or unexposed groups, rather the subjects are observed in order to determine both their exposure and their outcome status and the exposure status is thus not determined by the researcher.
