<\/a><\/p>\nLet’s say you have a sample with the given set of data such as:<\/p>\n
60, 70, 85, 52, 93, 58 , 71 (n=7)<\/p>\n
and you want find the mean and standard deviation.<\/p>\n
The first thing you need to do is to<\/p>\n
clear all data: shift, mode, 3 (All) =<\/p>\n
and set mode to statistics: mode, mode, 1 (SD)<\/p>\n
then you can begin to key in the data:<\/p>\n
just type the number and press m+ which mean add memory<\/p>\n
60 m+, after you press m+, then n=1 will appear on the screen. this means that the sample number you have added into your calculator is 1, and 60 is your first sample.<\/p>\n
continue adding all the data in your calculator:<\/p>\n
70\u00a0 m+<\/p>\n
85\u00a0 m+<\/p>\n
52 m+<\/p>\n
93 m+<\/p>\n
58 m+<\/p>\n
71 m+<\/p>\n
at the end , your n should be n=7<\/p>\n
Then, to find your mean just press<\/p>\n
shift 2 (s-var), 1 (x bar), =<\/p>\n
and the mean is 69.86<\/p>\n
to find the standard deviation, just press<\/p>\n
shift, 2 (s-var), 2 (xsigman), = 13.746 if your data is considered to be population<\/p>\n
shift, 2 (s-var), 3 (x sigma n-1), =14.84\u00a0 if you data is a sample.<\/p>\n
Therefore, you need to be aware about the data set that you have, whether it is a sample or population. (In this case, you need to find the standard deviation for a sample, so you should select 3 (x sigma n-1) ).<\/p>\n
so, here it is, simple right!<\/p>\n
