Describe three ways distributions can be represented (other than in a table that lists values for X and f(x)).© BrainMass Inc. brainmass.com June 22, 2018, 7:34 am ad1c9bdddf
The three ways in which the distribution can be represented other than in a table that lists the values for x and f(x) are given below :
1) Normal distribution : The normal distribution has two parameters, the mean mu and the standard deviation sigma. Once the parameters are known, the distribution is completely specified. It can be shown, although we will not do so (yet) that a good guess or estimate for mu is the mean of the observed values. An estimate for sigma is the standard deviation. Although the standard deviation is a positive number, the mean can assume any value. The distribution is symmetrical with mean, mode, and median ...
Ways of representing distributions are discussed. The solution is detailed and well presented.
