Fourteen patients have the following LOS:1,4,4,2,5,16,3,3,1,6,4,5,7,and 2. Compute the mean, median, and mode
Add them together and divide by 14 to find the mean.
Arrange them in order. The middle number is the median.
4 is the mode
So first what you want to do it two put the numbers in order from least to greatest.
1, 1, 2, 2, 3, 3, 4, 4, 4, 5, 5, 6, 7, 16
So to find the mode you want to see which number is listed the most. That would be 4.
To find the median you want to find the middle number of this set. What I do is I cross out the outermost number of the data until I narrow it down to one.
To find the mean, you would just add up all the numbers and then divide by 14, since there are 14 numbers.
Hope this helps!
