Document Summary
Quantitative research - involves the analysis of numerical data typically obtained from the administration of surveys and experiments. Descriptive statistics describe the group they belong to. Inferential statistics rely on data from small groups to speculate on the behavior of larger groups. Population: a collection of all humans living in a particular area of interest. Sampling: a sample is a representative portion of the overall population. Random- a randomly selected portion of the population. Stratified- an attempt to recreate a population by creating a proportion as a sample. Convenience- as the name implies, a sample chosen for convenience, the most common type of sample. Qualitative research - a scientific method that does not require statistical methods for collecting and reporting data.
