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.
Both of the these studies are non-experimental or observational studies. In other words, you aren't manipulating any of the variables, you are simply observing them. In descriptive studies, the researcher attempts to  describe  a group of individuals to document characteristics.
