Regression analysis can be described as ________.
A)a statistical hypothesis test in which the test statistic follows a Student's t-distribution if the null hypothesis is supported
B)a collection of statistical models in which the observed variance in a particular variable is partitioned into components attributable to different sources of variation
C)a statistical hypothesis test in which the sampling distribution of the test statistic is a chi-square distribution when the null hypothesis is true
D)a tool for building statistical models that characterize relationships among a dependent variable and one or more independent variables,all of which are numerical

Question

Quizplus · Accepted Answer

Regression analysis is a statistical method for building models to analyze the relationship between a dependent variable and one or more independent variables, all of which are numerical. These models can be used for prediction or understanding the underlying relationships between variables. Option A refers to a t-test, option B describes analysis of variance, and option C describes a chi-square test.
