You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a query to list out the following statistics from the table of events:

Statistics report

You'll need to use the COUNT, MAX and MIN functions respectively.

 

Your query won't need a GROUP BY, as you're not grouping by anything - just a SELECT and a FROM.

Save this query as Statto, then close it down.
