The statistical tests used for these checks are the Chi-Square Goodness of Fit Test (for equiprobability) and the Chi-Square Contingency Table Test (for independence). If there are sufficient data in your Open or Closed sequences, our Random Number Generator gives you the option to perform checks for equiprobability (Open Sequence only) and for pairwise independence. You need to set the initial number, like '1', the final number like '36', the number of draws, like '5'. For example, the order in which the numbers are drawn in a lotto - numbers from 1 to 90 will be listed in random order, or a lottery like 5 out of 36. It will give you an integer number between the two specified numbers only. The calculator generates an ordered sequence of numbers from a given range. For example, if generating a sequence of 0s and 1s, the independence check will see whether the 00, 01, 10, and 11 pairs are equally probable (which they are not in the above example). RANDBETWEEN function takes two arguments the Bottom value and the top value. This tool can be very useful for randomly determining winners of a giveaway and more. When checking for independence it is possible to look for complex sequential patterns but, in practice, a check on the independence of pairs of successive numbers will usually suffice. The random sequence generator is a very useful tool that allows you to generate a sequence of items from a list of inputs provided. For example, the sequence 01010101 shows the two outcomes (0 and 1) to be equally likely, but the data are not independent because 0 is always followed by 1 which is always followed by 0. Of course, data may pass the check for equiprobability but fail the check for independence. Second, the numbers are checked for independence to ensure that there are no particular sequential patterns. First, the data are checked for equiprobability to ensure that each number is equally likely to be generated. The output from a RNG or PRNG should ideally be checked to ensure that the sequence shows no evidence of non-randomicity. Welcome to Equiprobability and Independence
