The Statistical Functions can be executed from the keyboard or from the worksheet.
From the keyboard,
"Fantastic! A Quick & Powerful Calculating Tool for your EVERY Need! CustomCalc is by far the best Calculating App on the market hands down! This is a powerhouse Application that I will use daily. It has many unique functions that help both Business professionals, students and the scientific minded as well. It is fully customizable and can perform right along with many of today’s leading financial and scientific calculators. You can say goodbye to lugging these bad boys around anymore! Thank you! I love the currency exchange feature as well as the unit conversions and Trigonometric/Algebraic mode. I have been playing with it for a few days now and I honestly don’t think the developers of this app missed a thing within "
"Really like CustomCalc am a statistician and it's really good"
