Sample Variance

A statistic that measures the dispersion of a sample dataset, representing the average of the squared differences from the sample mean.

Population Variance

Population variance is a measure of the spread between numbers in a data set, representing the average of the squared differences from the population mean.

Random Sample

A selection taken from a group where each individual has the same probability of being chosen.

  • Initiate hypothesis assessments and outline confidence intervals for the means and variances of populations.
  • Compute and elucidate the variances of samples and the confidence intervals for variances within the population.
