Detailed explanation-1: -Variability refers to the extent that scores differ from one another and from the mean. Widely used measures of variability are the range, variance, and standard deviation. The range describes the spread of scores in a distribution. It is calculated by subtracting the lowest from the highest score in the distribution.
Detailed explanation-2: -Range, which is the difference between the largest and smallest value in the data set, describes how well the central tendency represents the data.
Detailed explanation-3: -Along with measures of central tendency, measures of variability give you descriptive statistics for summarizing your data set. The range is calculated by subtracting the lowest value from the highest value. While a large range means high variability, a small range means low variability in a distribution.
Detailed explanation-4: -Measures of Frequency: * Count, Percent, Frequency. * Shows how often something occurs. Measures of Central Tendency. * Mean, Median, and Mode. Measures of Dispersion or Variation. * Range, Variance, Standard Deviation. Measures of Position.
