单词 frequency distribution
释义 frequency distribution

A function describing the distribution of random drawings of a variable. If the variable, x, can take values over a continuous range from a minimum of a to a maximum of b, the frequency distribution will be f(x). The integral of f(x) from a to b, 0198607679.frequency-distribution.1.jpg , must be 1. The cumulative frequency distribution, F (c), shows the proportion of drawings equal to or less than c; 0198607679.frequency-distribution.2.jpg . Where the variable can only take one of a range of discrete values from a minimum of v1 to a maximum of vN, the frequency distribution takes the form f(vi) = fi, where ∑i f (vi ) = 1.
