The average ("mean") and median are measures of central tendency.

For the given time period, the price of XBI tends towards a value in the vicinity of 46.81 (the mean) and 36.19 (the median).

Standard Deviation and Coefficient Of Variation are measures of dispersion. These can be used to measure the volatility (risk) of a security, and also to estimate the expected ranges of the price.

Assuming a normal distribution, we expect to see 68% of values within one Standard Deviation of the mean (average), 95% of the values within two standard deviations of the mean, and 99% of the values within three standard deviations of the mean.

If the price of XBI goes above 77.31 (mean + 1 standard deviation) or below 16.31 (mean - 1 standard deviation), then the reader is urged to investigate further for a possible buying or selling opportunity.

If the price of XBI goes above 107.81 (mean + 2 standard deviations), then the reader is urged to investigate further as this would be an unusual event.
