Intro Variable stars are important in astronomy because they provide information on the properties of the stars. Variable stars vary in brightness over time and have periods ranging from a couple hours to hundreds of days. Moreover‚ pulsating stars are variable stars and have two types of pulsating stars‚ such as RR Lyrae and Cepheid. Additionally‚ the simulators in this lab gives individuals a visual model of how variable stars are determined and measured. Therefore‚ the simulators will give individuals

Multivariate analysis of variance (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent variables; 2. what are the interactions among the dependent variables and 3. among the independent variables.[1] Where sums of squares appear in univariate analysis of variance‚ in multivariate analysis of variance certain positive-definite
