Compairing probabilities between two sets
WebOne way to compare the two different size data sets is to divide the large set into an N number of equal size sets. The comparison can be based on absolute sum of of difference. THis... WebVideo transcript. - [Instructor] What we're going to do in this video is start to compare distributions. So, for example here, we have two distributions that show the various temperatures different cities get during the month of January. This is the distribution for Portland. For example, they get eight days between one and four degrees Celsius.
