Quantitative ResearchNameDateAcademic Institution What is Quantitative Research? Types of Quantitative ResearchExperimental studies, in which the researchers maintain control of all variables used in the study, manipulating one variable at a time. Correlational studies, which examine the relationship between two variables, often to determine whether an increase of one variable has an impact on the other variable. Causal-comparative studies explore relationships between a dependent and independent variable.Cohort studies are longitudinal, meaning they track changes over an extended period of time (Creswell & Creswell, 2017). Quantitative Sampling MethodsProbability sampling means any unit in the sample has an equal chance of being selected (Brannen, 2017). Types of probability sampling include:A simple random study, which makes random selections from the sample population.A systematic study, which uses a predetermined system for selections.A stratified system, which divides the population based on certain characteristics.A cluster study, which divides the population into clusters, then makes selections from the cluster. Non-probability sampling means units are purposely selected (Brannen, 2017). Types of non-probability sampling include:A convenience sample, with units selected based on convenience.A purposive sample, with units selected based on a predetermined criteria.A quota-based sample, with units selected on whether they meet certain characteristics.A snowball sample, with the researcher selecting
