WebJun 21, 2012 · The ecdf function applied to a data sample returns a function representing the empirical cumulative distribution function. For example: > X = rnorm(100) # X is a sample of 100 normally distributed random variables > P = ecdf(X) # P is a function giving the empirical CDF of X > P(0.0) # This returns the empirical CDF at zero (should be … WebA frequency is the number of times a value of the data occurs. According to Table 1.9, there are three students who work two hours, five students who work three hours, and so on. The sum of the values in the frequency column, 20, represents the total number of students included in the sample.
