Very clear thank you: A note to A level students reading this, you will more often than not be expected to use the sample standard deviation so the option "4:sx" is used
I'm from Australia and I'm studying for my final high school exams (the HSC) and I had no idea how to do this at all, this really helped me now I'm a pro lol. Thanks heaps!!!
Have good teacher and good explanation on how to use a scientific calculator in statistics , specially measures of Central tendency and Variation such Standard deviation, so thanks allot
Option 4 gives the sample standard deviation. You use that if you are using a sample of data from a larger population. In this case we are dealing with the data given, so we use sigma x (option 3) to give an exact value for the standard deviation of the data.
