How do you determine the significance level
WebHow do you test it? You take data from a random sample, and then you determine how likely (this is the confidence level) it is that a population with that assumed hypothesis and an assumed distribution would produce such data. You decide: if this data has a probability less than, say $95$% of coming from this population, then you reject at this ... WebOne way to calculate significance is to use a z-score. This describes the distance from a data point to the mean, in terms of the number of standard deviations (for more about mean and standard deviation, see our page on Simple Statistical Analysis ).
