Specify the column of data to analyze and the distributions to check it against. Click OK. Choose the distribution with data points that roughly follow a straight line and the highest p-value. In this case, the Weibull distribution fits the data best. Note These commands work just like the commands for the normal distribution. The binomial distribution requires two extra parameters, the number of trials and the probability of success for a single trial. The commands follow the same kind of naming convention, and the names of the commands are dbinom, pbinom, qbinom, and rbinom. The more closely the data follow a log-normal distribution, the closer the geometric mean is to the median, since the log re-expression produces a symmetrical distribution.

The standard deviation tells you on average how far the data varies from the mean. Some data points are of course farther from the mean, some closer to it. When many crowd very close to the mean (like in a "bell-shaped" distribution), only a few can range far from the mean at all (since the average must still work out to be µ).
