Here you'll learn how to represent the standard deviation of a normal distribution on a bell curve. Then you'll use the Empirical Rule to solve normal distribution problems. #Math #Empirical Rule #CK-12
NORMAL CURVE - Bing Images The normal distribution curve is the basis for probability theory. Probability theory builds on this distribution. If something is rare, occurring more than two standard deviations above or below the mean, we probably caused it to happen by our research manipulation. Therefore, we have found statistical significance, p < .05. Use graphic in PowerPoint as explanation of probability.
