"Watch this video about Basic Mathematical Operations for Computations with MATLAB in Exploratory Data Analysis with MATLAB. In this module you’ll write small pieces of code to extend your analysis. You’ll calculate summary statistics on groups of data and determine if variables are correlated. You’ll extend your ability to filter data to defining conditions across multiple variables. You’ll also modify categorical data to remove, combine, or create new categories to use for defining groups."
