What is a percentile? What is a percentile? With all these percentages being used, you can use the z-scores and the normal curve to calculate the percentage of data that falls BELOW or ABOVE that data point. You will be using the calculator to help you with this. Calculator Steps: Below the data point: 2nd Vars . Hit 2: normalcdf(
