The Empirical Rule, which is also known as the three-sigma rule or the 68-95-99 7 rule, represents a high-level guide that can be used to estimate the proportion of a normal distribution that can be found within 1, 2, or 3 standard deviations of the mean
- Empirical Rule Calculator Mean Standard Deviation
For a bell-shaped (normal) distribution: Approximately 68% of the data values will fall within 1 standard deviation of the mean, from $67$ to $165$ Approximately 95% of the data values will fall within 2 standard deviations of the mean, from $18$ to $214$

Scores on IQ tests have a bell-shaped distribution with mean \(\mu =100\) and standard deviation \(\sigma =10\) Discuss what the Empirical Rule implies concerning individuals with IQ scores of \(110\), \(120\), and \(130\)

True or False: Chebyshev's inequality applies to all distributions regardless of shape, but the empirical rule holds only for distributions that are bell shaped A False, both Chebyshev's inequality and the empirical rule will only work for bell-shaped distributions

- A certain standardized tests math scores have a bell-shaped . . .
The empirical rule, also known as the 68-95-99 7 rule, states that for a normal distribution, about 68% of the observations fall within one standard deviation of the mean, about 95% fall within two standard deviations, and about 99 7% fall within three standard deviations
- 2. 2. 7 - The Empirical Rule | STAT 200 - Statistics Online
The 95% Rule states that approximately 95% of observations fall within two standard deviations of the mean on a normal distribution Normal Distribution A specific type of symmetrical distribution, also known as a bell-shaped distribution
- Normal Distributions and the Empirical Rule
Empirical Rule - When a histogram of data is considered to meet the conditions of a “Normal Distribution”, (i e its graph is approximately bell-shaped), then it is often possible to categorize the data using the following guidelines (Note: → symbol used for standard deviation )
