Apr 23 2022 nbsp 0183 32 Normal distributions are denser in the center and less dense in the tails Normal distributions are defined by two parameters the mean and the standard deviation 68 68 of the area of a normal distribution is within one standard deviation of the mean 7 1 Introduction To Normal Distributions Statistics LibreTexts. Oct 3 2018 nbsp 0183 32 To draw a normal curve we need to know the mean and the standard deviation Example 1 Suppose the height of males at a certain school is normally distributed with mean of 70 inches and a standard deviation of 2 inches Sketch the normal curve Step 1 Sketch a normal curve Step 2 The mean of 70 inches goes in the middle Mar 19 2025 nbsp 0183 32 The normal distribution creates a perfect bell shaped curve centered at the mean The spread is controlled by the standard deviation with the famous 68 95 99 7 rule showing us how values cluster around the mean The normal distribution tells us approximately 68 of women would be between 5 1 5 and 5 6 5 tall about 95
