Question

Descriptive statistics are primarily used for data reduction, meaning summarizing and organizing data in a way that makes it easier to understand and analyze. It involves using measures of central tendency (such as mean, median, mode) and measures of variability (such as range, variance, standard deviation) to provide a comprehensive overview of a variable's distribution. While descriptive statistics can be used to provide some information on associations between variables, they cannot determine causality, which requires multivariate analyses. They also do not involve data expansion, which refers to techniques such as factor analysis or cluster analysis that are used to create new variables from existing ones.
