what is a good relative average deviation

document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Statology is a site that makes learning statistics easy by explaining topics in simple and straightforward ways. The higher the deviation, the further the numbers are from the mean.

A highly volatile stock is inherently riskier, but that risk cuts both ways. to the mean When people say volatility, they usually mean standard deviation. The average deviation of a score can then be calculated by dividing this total by the number of scores. Here is a quick summary and then an example is given that might help. In addition, options contracts are priced based on the implied volatility of stocks (or indices), and they can be used to make bets on or hedge volatility changes. On an absolute basis, investors can look to the CBOE Volatility Index, or VIX. {\displaystyle i} Square each variance, then add all squared variances together. A stop-loss order is another tool commonly employed to limit the maximum drawdown. The RSD is often referred to as the coefficient of variation or relative variance, which is the square of the coefficient of variation. or GCV by inverting the corresponding formula.
