What makes a “Statistical Programmer” different from a “Programmer”
... tests are less than alpha—for example, if P < .05—the researchers would conclude that their study results are statistically significant. A relatively simple way to interpret P values is to think of them as representing how likely a result would occur by chance. For a calculated P value of .001, we c ...

... • What happens when a value doesn’t quite fit in exactly one, two or three standard deviations? • We can use z-scores and z-tables! • Z-scores tell us exactly how many standard deviations away a value is from the mean and the z-table gives us the probability a value is below that amount. ...
