You can find the statistics at the bottom of the order details page. No need to click a different tab to show the statistics here! You can also find them on the customer update page under the add-ons tab. This includes the following statistics which can easily be extended:
When the customer has created his/her account (time ago)
When the customer has logged in for the last time (time ago)
