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.
In descriptive statistics, a box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles. Box plots may also have lines extending vertically from the boxes indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. Outliers may be plotted as individual points. Box plots are non-parametric: they display variation in samples of a statistical population without making any assumptions
