  • Statistical Concepts

    STANDARD DEVIATION The standard deviation is the most common and useful measure because it is the average distance of each score from the mean. Standard deviation is a measure of the spread or dispersion of a set of data.

  • Dispersion Measures

    This measure of dispersion is known as the variance, and the square root of the variance is known as the standard deviation.

  • What statistical measures are used for describing dispersion?

    Difference is as follows: Range is the difference between the highest and lowest scores in a distribution. It is affected by the outliers, hence it has limited use. Most commonly used measures of dispersion are variance and standard deviation.

  • Importance of Central Tendency and Dispersion in Statistics

    This relatively large standard deviation (a measure of dispersion) indicates that the data is fairly spread out around the mean value of 85%.

  • Sample statistics

    It also explaines which measure, mean or median is a better typical value and whether standard deviation or inter-quartile range is a better measure of dispersion.

  • Mean and Standard Deviation

    A measure of statistical dispersion is a real number that is zero if all the data are identical, and increases as the data becomes more diverse." Measures of dispersion provide a more complete picture.
