How do I interpret P values?If the P value is less than that critical value, you reject the null hypothesis. If it is equivalent or higher than the critical value, you fail to reject the null hypothesis.
Keep in mind, smaller is "better" when it comes to interpreting P values for significance. The closer to 0 it is, the stronger the evidence that you should reject the null hypothesis.
What is a Z score?The Z score is a measure of how many standard deviations[1] a data point is away from the mean. Z scores rely on the standard normal distribution[2] (or Gaussian) which has a mean of 0 and a standard deviation of 1. It i...
