Quantitative research options are predetermined and a large number of respondents are involved. By definition, measurement must be objective, quantitative and statistically valid. Simply put, it’s about numbers and objective hard data.The sample size for a survey is calculated by statisticians using formulas to determine how large a sample size will be needed from a given population in order to achieve findings with an acceptable degree of accuracy.
Quantitative research is explaining phenomena by collecting numerical data that are analyzed by using mathematically based methods (in particular statistics). Typical quantitative methods include:
Field research / Fieldwork
Field research or fieldwork is the collection of information outside of a laboratory, library or workplace setting. Field research involves a range of well-defined methods:
Fixed point monitoring
In statistics, an interaction may arise when considering the relationship among three or more variables, and describes a situation in which the simultaneous influence of two variables on a third are not additive. Most commonly, interactions are considered in the context of regression analyses.
It is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables.
