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.
While a box and whisker plot displays several important features of a distribution, it does not show the distribution of the data in as much detail as a histogram or dot plot. Box plots are useful, however, for quickly indicating whether the distributions are skewed, and whether there are any outliers in the data set. Box plots are also useful when representing large amounts of data, and when comparing data sets. Box plots show the shape of the distribution of the data, the central value, and the variability. It uses the median as its center value and presents a brief picture of the distribution of the other values in the form of its five statistical summary.
