Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data. 10 units. In a right triangle, however, one of the angles is already known: the right angle, or the 90o angle. The lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ . Using this property, we can calculate the measure of the unknown angles. Line t and line s are transversals. The most common way to measure angles is in degrees, with a full circle measuring 360 degrees. sin ∠A = opposite / hypotenuse cos ∠A = adjacent / hypotenuse tan ∠A = opposite / adjacent .
