Even if you live a relatively calm and mundane life, every now and then something can happen that deviates from your standard routine. Sometimes it’s a good thing, other times it’s not.The p-value is a worst-case bound on that probability. The p-value can be thought of as a percentile expression of a standard deviation measure, which the Z-score is, e.g. a Z-score of 1.65 denotes that the result is 1.65 standard deviations away from the arithmetic mean under the null hypothesis.Standard deviation is a measure of variation in data.
