Metric data refers to data that are quantitative, and interval or ratio in nature. Also, it is important to understand the magnitude of missing values in observations and to determine whether to ignore them or impute values to the missing observations. It can also examine latent variables that were not directly measured in the analysis. In addition to writing for the CareerFoundry blog, Emily has been a regular contributor to several industry-leading design publications, including the InVision blog, UX Planet, and Adobe XD Ideas. She has been published on Yahoo! This is measured in terms of intracluster and intercluster distance. With MANOVA, it's important to note that the independent variables are categorical, while the dependent variables are metric in nature. Whereas analysis of variance (ANOVA) assesses the differences between groups (by using T tests for two means and F tests between three or more means), MANOVA examines the dependence relationship between a set of dependent measures across a set of groups. Multiple regression, or multiple linear regression, is the most widely used multivariate technique and is often used in forecasting.
