What is standard error and standard deviation?

The standard deviation (SD) measures the amount of variability, or dispersion, from the individual data values to the mean, while the standard error of the mean (SEM) measures how far the sample mean (average) of the data is likely to be from the true population mean.A AP

How do you find the mean and standard deviation of a random variable?


  1. A Random Variable is a variable whose possible values are numerical outcomes of a random experiment.
  2. The Mean (Expected Value) is: μ = Σxp.
  3. The Variance is: Var(X) = Σx2p − μ2
  4. The Standard Deviation is: σ = √Var(X)

What is 1 standard deviation from the mean?

95% is 2 standard deviations either side of the mean (a total of 4 standard deviations) so: 1 standard deviation. = (1.

What is a low standard deviation value?

Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out. A standard deviation close to zero indicates that data points are close to the mean, whereas a high or low standard deviation indicates data points are respectively above or below the mean.
