Open the Power BI file in the above folder. As well as a list of films, it contains a table giving how many times the author would need to pop out for a comfort break during each film's screening:
From this table you should be able to make a reasonable guess at the author's age ...
Note that the two tables are not joined together - nor should they be for this exercise.
In the Films table create a calculated column called NumberBreaks which shows for each film the number of breaks needed. To do this you want to pick out the value of the Breaks column where:
To refer to this film you can either use the EARLIER function or create a variable.
Because you're not using an aggregation function, you'll need to use the VALUES function within CALCULATE to pick out what you can be confident is the only Breaks column value returned.
When you've finished, you should be able to create the following matrix:
You're going to be popping out more to see multiple-Oscar films like Titanic and The Return of the King than for less successful films, because they last longer on average.
If you still have time, try creating a second calculated column to do the same thing, but this time using the method you didn't use the first time.
Save this file as Wee report, then close it down.
