Hypothesis testing and experimental design
... Using these basic statistical techniques, we can devise some tests to determine whether certain data gives evidence that some effect “really” occurs in the real world Fundamentally, this is evaluating whether things are (likely to be) true about the population (all the data) given a sample Lots of c ...

Hypothesis Testing
... • If the null hypothesis occurs with 5% or lower chance then you would reject H0 and conclude that the alternate hypothesis is statistically significant • If the null hypothesis occurs with 1% or lower chance then Ha is strongly significant ...

Why Statistics Is Not Mathematics and Why We Should Care About
... Statistics is a science in my opinion, and it is no more a branch of mathematics than are physics, chemistry, and economics; for if its methods fail the test of experience – not the test of logic – they are discarded. - John Tukey, 1962 ...
