The sales manager of a computer software company monitors the sales figures and sales visits from the previous 26 weeks. Because the number of sales visits each week impacts the amount of sales, the manager wants to monitor these variables at the same time.
Because this data contains two dependent measurement variables, you can use it to demonstrate T²-Generalized Variance Chart.
|Week||The week identification number|
|Sales||The sales for the week|
|On-Site Visits||The number of in-person sales visits for the week|
