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.
In experiments, these are called dependent and independent variables respectively. When a researcher gives an active drug to one group of people and a placebo, or inactive drug, to another group of people, the independent variable is the drug treatment.n a descriptive study, the researcher would examine how diabetes (a variable) is related to a person's genetic heritage (another variable). Case example of descriptive study variables Variables are important to understand because they are the basic units of the information studied and interpreted in research studies.
