WebApr 2, 2024 · The deviations are used to calculate the standard deviation. If the numbers belong to a population, in symbols a deviation is \(x - \mu\). For sample data, in symbols a deviation is \(x - \bar{x}\). The procedure to calculate the standard deviation depends on whether the numbers are the entire population or are data from a sample. Web4. The symbol used for the variance of a sample is: s^2. The symbol used for the variance of a population is: σ^2. A population of N=400 has µ=25 and σ=9. What is the population variance? 81.
