Binomial Distributions:
The Central Limit Theorem states that if a sample is sufficiently large (N>30) the sample will have an approximately normal (mound shaped) distribution.
Therefore:
Chebyshev's Rule:
provides no information on the fraction of data included within 1 Std. Dev.
at least 3/4 of the data will fall within 2 Std. Dev. of the mean.
at least 7/8 of the data will fall within 2 Std. Dev. of the mean.
Empirical Rule:
will include approximately 68% of the data.
will include approximately 95% of the data.
will include approximately 99.7% of the data.
