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

For the given time period, the price of SDS tends towards a value in the vicinity of 380.22 (the mean) and 246.96 (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 SDS goes above 727.65 (mean + 1 standard deviation) or below 32.80 (mean - 1 standard deviation), then the reader is urged to investigate further for a possible buying or selling opportunity.

If the price of SDS goes above 1,075.07 (mean + 2 standard deviations), then the reader is urged to investigate further as this would be an unusual event.
