Eliminating ten percent of the members on each end would bring the study down to eight men , and this population might not be large enough to obtain accurate results that can be duplicated . In a study this small , researchers should prefer to have a range of heights and weights , because they can be easily tracked .

If the most extreme cases are weeded out , then that data will not be included in the study and it may be relevant to the origins of obesity If the study included several hundreds or thousands of people , then it would be necessary to trim the mean in to bring the study down to a size that is easily manageable… [banner_entry_footer]
