In chapter four, you will combine what you’ve learned in previous chapters to calculate and analyze LTV, CAC, and their ratio. You’ll learn how to build these metrics, such as average order size, age, and lifespan, from their component parts and examine changes in them. Returning to earlier work on paid marketing, you’ll analyze changes in CAC over time through a unioned data set, gaining exposure to connived data sets in Tableau. You’ll then wrap up the course by calculating LTV/CAC.
