I have statistics coursework and for standard deviation you must calculate the mean.
The numbers are to do with times and the numbers are like: 01:08.4
how would i type this in so my scientific calculator picks it up?
Thankyou for your time :)
This is brilliant! Thankyou so much!
You can change the minutes into decimal hours by dividing by 60, like this: 8.4/60 = 0.14,
so 1:08.4 = 1.14, etc.
If, at the end, you wish to turn the decimal hours back into minutes, multiply by 60.
