Karl Pearson first used the term "Standard Deviation" in writing in 1894 subsequent its use in his lectures. Standard Deviation is quite crucial in financial issues. A large standard deviation indicates that the data points are far from the mean and a small standard deviation indicates that the data points are clustered much closer to the mean. When investing, standard deviation serves as a measure of uncertainty. Designated standard deviation of a group of repeated measurements should give the precision of those measurements. Investors deciding whether measurements agree with a theoretical prediction must determine if the standard deviation of those measurements is of extreme importance. Investors can gain common sense practical value when online investing by acquiring an understanding of the standard deviation of a set of values and in appreciating how considerably the variations are from the common (mean) of stocks & options and the market indices.

The greater the variance in standard deviation, the greater the risk the security will have. Technical analysts like to use an analysis tool called the "Bollinger Bands", devised by John Bollinger to determine the highness and lowness of cost relative to earlier trades. These important Bollinger Bands are made up of a middle band being an N-period (usually the simple moving average), an upper band at K times an N-period standard deviation above the middle band, and a lower band at K times an N-period standard deviation under the middle band, where N and K are normally 20 and 2 respectively. Being of vital importance, Bollinger Bands are helpful in recognizing patterns and comparing price actions of stocks and therefore are really helpful for creating systematic trading choices. Being used with other tools and data, Bollinger Bands are proficient management tools that have a practical use of standard deviation with online investing.
