Why are descriptive statistics so important?
Descriptive statistics helps facilitate data visualization. It allows for data to be presented in a meaningful and understandable way, which, in turn, allows for a simplified interpretation of the data set in question.
Why is descriptive statistics important in research?
Descriptive statistics allow a researcher to quantify and describe the basic characteristics of a data set. As such, descriptive statistics serve as a starting point for data analysis, allowing researchers to organize, simplify, and summarize data.
