Issue to answer final question of the quiz

Hi, the last question of the quiz asks to give the variance of a sample, with 2 decimals. I’m pretty sure I’ve got the correct result, but can’t find the way to input the answer in a way that it will be correctly interpreted. So the answer to this question inevitably returns as ‘wrong’. Could someone explain how I should proceed ? Imagine the answer is 8/3 so 2.6666… (it’s not) → I tried 2.67 ; 2.66 ; 2,67 (with a comma) ; 2,66 ; 2.6 ; 2.7 ; … nothing would work. So I’m stuck and above all I’d like to understand why I don’t get this right :slight_smile: Thanks a lot for the help.

If it says 2 decimals it should be x.yz thats what I understand, maybe you result is wrong!

Hi, I was able to solve the final question. You have to do all your calculations using all the decimals. Only when you have to submit the answer you can use 2 decimals. When you use all the decimals the answer varies a little bit. :slight_smile: And the format is correct, for example: 9.99. It is not necessary to use comma.
