... a value which divides the sample in to half. As the mean and median are not equal, the data set is skewed. As in the present case, the mean is greater than the median, the dataset is positively skewed. The histogram of the dataset shows that it is having a long tail. As the dataset is skewed, median ...

Testing Hardy–Weinberg equilibrium with a simple root
... HWE. The classic tests, tuned to detect relative discrepancies, can be blind to overwhelmingly large discrepancies among common genotypes that are drowned out by expected finite-sample size fluctuations in rare genotypes. The root-mean-square statistic, on the other hand, is tuned to detect deviatio ...

For a consecutive match first occurring on roll 4, we use the probability that second roll did not match first roll, probability 5/6, that third roll did not match second roll, probability 5/6, and ...

The mean of the squares of the deviations of every observation from their mean is a measure of spread and is called the variance. The standard deviation is the square root ...
