2 standard deviation. of the . mean (between ( + 2 and ( – 2). 99.7%. of data falls within . 3 standard deviation. of the . mean (between ( + 3 and ( – 3). Since the bell curve for normal distribution is symmetrical about the mean, we can use the 68-95-99 rule to determine the probabilities of the individual sections under the curve.

Using standard deviation in a . normal curve. A study of statistical data reveals that when a normal distribution occurs, 68% of the population will have a value within one standard deviation of the mean, and 95% of the population will have a value within two standard deviations of the mean.

allows students to interact with the standard deviation σ by the sliding the value from small (less than 1) to large (greater than 1), and this will automatically change the shape of the bell-curve as they slide the standard deviation value.

The z-curve even has a formula, we don’t need it but it is. We can even show what a standard deviation is on the normal curve. Draw the bell-shaped curve and find where instead of getting steeper its getting flatter, from the center to that point is 1 standard deviation. We would like you to know how much of data from a normal distribution is ...

Draw an appropriate bell curve that represents 1, 2, and 3 standard deviations, [don’t forget the mean] and include the percent of the sample/population that is captured within each standard deviation.

Standard deviation: “mean of the means.” Use a normal distribution curve. The standard deviation is a statistic that tells you how tightly all of the data points are clustered around the mean in a set of data. When the examples are pretty tightly bunched together and the bell-shaped curve is steep, the standard deviation is small.
