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. Standardising population data by calculating z-scores (1 or 2 lessons)

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.

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, being the square root of that quantity, therefore measures the spread of data about the mean, measured in the same units as the data. Said more formally, the standard deviation is the root mean square (RMS) deviation of values from their arithmetic mean. ... Normal (bell curve) - Poisson - Bernoulli Correlation Pearson ...
