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.
Experimental studies are typically preferred over observational studies because they allow for more control. A common problem with observational studies is that there may be other variables influencing the results that the researchers did not take into account.
