Find the interquartile range. Now that we've defined Q1 and Q3, we need to calculate the distance between these two variables. The distance from Q1 to Q3 is found by subtracting Q1 from Q3. The value you obtain for the interquartile range is vital for determining the boundaries for non-outlier points in your data set.

Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. About 1,500 species of starfish occur on the seabed in all the world's oceans, from the tropics to frigid polar waters.They are found from the intertidal zone down to abyssal depths, 6,000 m (20,000 ft) below the surface.Starfish are marine invertebrates.he tube feet, spines and pedicellariae are sensitive to touch. The tube feet, especially those at the tips of the rays, are also sensitive to chemicals, enabling the starfish to detect odour sources such as food. There are eyespots at the ends of the arms, each one made of 80â200 simple ocelli.
