Once I know whether a variable is numerical or categorical, I can compute statistics appropriately. I’ll be delving into additional types of statistics later, but the very first, simplest statistics that I want to review are:
- Counts for a categorical variable
- Minimum and maximum values in addition to mean and median for a numerical value
To handle my initial analysis of the categorical variables, I can add new measures to the modelto compute the count using a DAX formula like this, since each row in the games table is unique:
Game Count = countrows(games)
It’s interesting seeing Stacia use Power BI for exploratory analysis. My personal preference would definitely be to dump the data into R, but there’s more than one way to analyze a data set.
