As the saying goes: Results may vary. When do I expect a difference to be significant and not the result of random fluctuations? Excel has all the tools to find out.

If you have negative values in the data, the data might be negatively skewed. Should your if(skewed...) formula use an ABS() absolute value for the skew factor ?

Thank you very much Dr.!

Prof., does our choice of p-value determine what we mean by random? I mean, if we choose a 95% significance, aren't we defining observing events of probability 5% or lower to be as good as random?

Thanks for the videos. I am just having 1 questions , if there are two set of samples the shouldn't be the degrees of freedom be n1+n2-2 ?

Not in this video, where we use the difference between pairs of variables, which is one set.

please how will I calculate statistical significance if my data is not linearly distributed, my data is a sound wave.

See my video kzbin.info/www/bejne/qXa9mWt-eLiUrs0 or use bootstrapping: kzbin.info/www/bejne/eJKvYmdjeJ2Gm6s. You will find also further information in my book on science: www.genesispc.com

Can u please explain the formula for skewed (e.g. skewed>2*SQRT...)? Thanks.
@fernandojackson72077 жыл бұрын
Joji, it is a rule of thumb used to decide whether a distribution is skewed.
