The cause of gastrointestinal problems for dogs is often related to their tendency to eat things they shouldn't, while cats may suffer digestive system upset as a result of parasites in their prey. For cats and dogs, studies show that a healthy population of gut bacteria is vital to a fit gastrointestinal tract.
In the simplest box plot the central rectangle spans the first quartile to the third quartile (the interquartile range or IQR). A segment inside the rectangle shows the median and whiskers above and below the box show the locations of the minimum and maximum.he box plot (a.k.a. box and whisker diagram) is a standardized way of displaying the distribution of data based on the five number summary: minimum, first quartile, median, third quartile, and maximum.
Example: Box and Whisker Plot and Interquartile Range for. 4, 17, 7, 14, 18, 12, 3, 16, 10, 4, 4, 11. Put them in order: 3, 4, 4, 4, 7, 10, 11, 12, 14, 16, 17, 18. Cut it into quarters: 3, 4, 4 | 4, 7, 10 | 11, 12, 14 | 16, 17, 18. In this case all the quartiles are between numbers: Quartile 1 (Q1) = (4+4)/2 = 4.
