Deviation is the action of being or doing something different from the usual or common way, or the amount by which a measurement is different from a fixed number or amount. Learn more about the meaning, usage and examples of deviation in English and Business English.
Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.
- The procedure to calculate the standard deviation is given below: Step 1: Compute the mean for the given data set. Step 2: Subtract the mean from...
- Standard deviation tells us how far is the mean from each observation in the given data set. In other words, it shows the typical deviation from th...
- Standard deviation indicates how the spread of observations of a data set is from the mean by studying at the variance’s square root. The variance...
- Consider the data set: 2, 1, 3, 2, 4. The mean and the sum of squares of deviations of the observations from the mean will be 2.4 and 5.2, respecti...
- A standard deviation is used to determine how estimations for a group of observations (i.e., data set) are spread out from the mean (average or exp...
Learn the meaning of deviation as an act or instance of deviating, such as a departure from a norm, a standard, or a course. See synonyms, examples, word history, and related phrases of deviation.
In mathematics and statistics, deviation serves as a measure to quantify the disparity between an observed value of a variable and another designated value, frequently the mean of that variable. Deviations with respect to the sample mean and the population mean (or "true value") are called errors and residuals, respectively.

Anything that varies from the accepted norm or standard is called a deviation. It is common in math and science, but it can refer to anything that differs from the expected. Deviation in nature is an important part of evolution.
