The end result of sampling is to get a representative sample, or a small collection of units or cases from a much larger collection or population. In theory, the researcher can study the smaller group and produce accurate generalizations about the larger group. Researchers focus on the specific techniques that will yield highly representative samples much so in similarities as a population. Quantitative researchers tend to use a type of sampling based on theories of probability from mathematics, called probability sampling.Sampling is the group of individuals who participate in your study. These are the individuals who will participate in a qualitative study. People who could have been participants in your study but did not actually participate are not considered part of your sample.

The formula I = PRT is used to calculate the amount of simple Teresa earned. Solve this formula for T
Dmitrij [34]

To solve this formula for T, divide both sides of the original equation by PR:

  I         PRT

------ = ---------   =>    T = I / (PR)

PR        PR

Please note:  Because the formula I = PRT involves neither addition nor subtraction, the final formula for T cannot involve either addition nor subtraction.  That leaves:

T = I P/R

T= IPR

The second formula here is incorrect; we cannot solve I = PRT for T simply by rearranging the order of the variables.  This leaves T = I P/R as a possible answer, but this answer does not agree with my   T = I / (PR).  Please double check to ensure that you have copied down the four possible answers correctly.
