The writer would then classify data based on age, gender, readmission and length of stay. Data would be communicated through construction of a frequency histogram of those who were readmitted and their initial length of stay (example table 2) and another frequency histogram that shows those who were not readmitted and their initial length of stay (example table 3). Comparison of these histograms would demonstrate to the audience if the length of stay affects hospital readmission rates of congestive heart failure patients. According to Larson and Farber (2015), a frequency histogram is a graph that represents the frequency distribution of a data set. It is easier to look at a bar representation graph for volume related data, instead of a
