Now, let's say we had 7 people admitted for COPD with individual LOS of 3, 4, 6, 6, 6, 8, and 12 days. We have quite a range with these figures. The range is calculated by taking the highest number and subtracting the lowest, so what is the range for this dataset_______?____________
What if we wanted t know what is the usual length of stay? There are three basic ways to measure the "middle" or central tendency. The mean, the mode, and the median.
The mean is just the average so calculate the average of the data set _____?______ this is the formula: Average Length of Stay = Total length of stay (discharge days)/Total discharges (includes deaths)
The mode is the most frequent amount in a data set. What is the mode of this dataset _______?________
The median is the number in the middle. What is the median of this dataset? ___________?_____________
There is one additional method called the geometric mean length of stay, which is more accurate but is a more complex calculation.
The median, which is easy to calculate, is also a food measure of central tendencies because outlier values have less influence with the median as compared to the mean.
