Statistical terms.

  • Mean:The mean is the arithmetic average of a set of values. Mean is calculated as the sum of all the given elements divided by the total number of elements.
  • Confidence Interval: The confidence interval gives an estimated range of values which is likely to include an unknown population parameter, the estimated range being calculated for a given set of sample data collected. The width of the confidence interval gives us some idea about how uncertain we are about the unknown parameter. A very wide interval may indicate that more data should be collected before anything very definite can be said about the parameter.
  • Standard Deviation: Standard deviation is a statistical measure of spread or variability. The standard deviation is the root mean square (RMS) deviation of the values from their arithmetic mean.
  • Standard Error: The standard error is a method of measurement or estimation of the standard deviation of the sampling distribution associated with the estimation method.
