The first step is to calculate the z-score, which tells you how many standard deviations away from the mean your data point is. To do this, take your data point and subtract the mean. Then, divide by the standard deviation. can i exercise with osteoporosisWebDec 9, 2024 · The way to interpret that p-value is: observing 38 heads or less out of the 100 tosses could have happened in only 1% of infinitely many series of 100 fair coin tosses.
