Case summary: When you$$re working with a new or unknown set of data, validating the data is very important. When you make a data request, the IT manager who fills the request should also provide some summary statistics that include the total number of records and mathematical sums to ensure nothing has been lost in the transmission. This lab will help you calculate summary statistics in Power BI and Tableau Desktop.
