Pol 600: Research Methods
... All of what we have done so far assumes that we are dealing with populations. Populations are complete sets of all observations of interest. In reality, true populations are often unknown. Most of the time, what we have in social science is sample data. Samples are simply subsets of a population. Be ...

... Subjective Method When economic conditions and a company’s circumstances change rapidly it might be inappropriate to assign probabilities based solely on historical data. We can use any data available as well as our experience and intuition, but ultimately a probability value should express our ...
