PDF Chapter 5: Quantitative Research Methods
Quantitative research assumes that there is no such thing as complete objectivity, so measures are put in place to increase con dence levels and reduce research subjectivity. The questions determine the method. If a quantitative answer is needed, such as how many or what percentage, then quantitative research is used.

Now, if we divide the frequency with which a given mean was obtained by the total number of sample means (36), we obtain the probability of selecting that mean (last column in Table 10.5). Thus, eight different samples of n = 2 would yield a mean equal to 3.0. The probability of selecting that mean is 8/36 = 0.222.
PDF Key Elements of a Research Proposal
The basic procedure of a quantitative design is: 1. Make your observations about something that is unknown, unexplained, or new. Investigate current theory surrounding your problem or issue. 2. Hypothesize an explanation for those observations. 3. Make a prediction of outcomes based on your hypotheses.
