Spread Out Statistic Document For Free

The simplest measure of spread in data is the range. It is the difference between the maximum value and the minimum value within the data set. In the above data containing the scores of two students, range for Arun = 100-20 = 80; range for John = 80-45 = 35.

The spread of a distribution tells you the range of your data. If your spread is small, then your data covers a short range. If your spread is large, then the data covers a larger range.

Definition. Measures of spread describe how similar or varied the set of observed values are for a particular variable (data item). Measures of spread include the range, quartiles and the interquartile range, variance and standard deviation.

Spread describes the variation of the data. Two measures of spread are range and standard deviation.

Summary Statistics: Measures of Spread The measure of spread is also referred to as Dispersion, Variability, or Frequency Distribution. This measure helps us understand how the responses are spread out. The three aspects of spread are range, SD (Standard Deviation), and Variance.

The symbol ?2 represents the population variance; the population standard deviation ? is the square root of the population variance. The symbol s2 represents the sample variance; the sample standard deviation s is the square root of the sample variance.

Spread. The main measure of spread that you should know for describing distributions on the AP® Statistics exam is the range. The range is simply the distance from the lowest score in your distribution to the highest score. To calculate the range, you just subtract the lower number from the higher one.

If a histogram is bell shaped, it can be parsimoniously described by its center and spread. The center is the location of its axis of symmetry. The spread is the distance between the center and one of its inflection points.
