Statistics

1. Chebyshev's theorem shows that in all samples most of the data lie within three standard deviations of the average.

2. One of the advantages of using a sample average instead of a single observation to estimate the population mean is that the sample average is more likely to be close to the population mean.

3. The empirical rule cannot be applied to skewed distributions.
