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.
Answer Wiki. There are no independent variables in observational studies. In an observational study, the researcher compares subjects against a control group and comes to a conclusion. Hypothetical example: if we have a research study comparing the risk of developing liver cancer between (1) people who drink some alcohol daily, and (2) teetotalers.
Observational studies are ones where researchers observe the effect of a risk factor, diagnostic test, treatment or other intervention without trying to change who is or isnât exposed to it. Cohort studies and case control studies are two types of observational studies. Cohort study: For research purposes, a cohort is any group of people who are linked in some way. For instance, a birth cohort includes all people born within a given time frame.
