Given a simple random sample of size n, a bootsA continuous random variable has infinitely many values, and the collection of values is not countable. (That is, it is impossible to count the individual items because at least some of them are on a continuous scale, such as body temperatures.)trap sample is another random sample of n values obtained with replacement from the original sample. Note that a bootstrap sample involves sampling with replacement, so that when a sample value is selected, it is replaced before the next selection is made
