Questions: The picture below has 3 normal curves plotted on the same set of axes. Compare the means of the 3 distributions. Compare the standard deviations of the 3 distributions. Explain your reasoning. The three distributions all have the same mean because each curve has the same center and the three distributions have the same standard deviation because the distance from each graph's mean to the transition point or inflection point is the same for each distribution. The three distributions have different values for the mean because each curve has a different center; but, on the other hand, the three distributions have the same standard deviation because the distance from each graph's mean to the transition point or inflection point is the same for each distribution. The three distributions have different values for the mean because each curve has a different center and the three distributions have different standard deviations because the distance from each graph's mean to the transition point or inflection point is different for each distribution. The three distributions all have the same mean because each curve has the same center; but, on the other hand, the three distributions have different standard deviations because the distance from each graph's mean to the transition point or inflection point is different for each distribution.
