How to describe a sample Inferential Statistics Bi Modal Central TendencyMultimodal having more than 2 modes Unimodal When distribution only has one mode -the frequencies progressively decline as they move away from the mode. Symmetrical distributions are usually uni modal. bimodal means you have not defined your population if you find a bimodal Mode most frequently occurring measure (value or category) in (distribution) data Mean called location parameter most frequen...
