The width of the Particle Size Distribution is an important statistical property. (of a distribution) having or occurring with two modes.Compare unimodal. Examples of Unimodal Distributions. Interpretation of an average of biomodial distribution is problematic because the data represents non- normal distribution. Implications of a Bimodal Distribution The mode is one way to measure the center of a set of data. Mode 1 is optimized for areas that are more predictable and well-understood. Bimodal histograms can be skewed right as seen in this example where the second mode is less pronounced than the first. However, this information is fragmented, and studies of bimodality are mainly restricted to monthly rainfall totals. 20 examples: An unexpected finding was a suggested bimodal distribution in the female Having or exhibiting two contrasting modes or forms: "American supermarket shopping shows bimodal behaviorcareful, nutritious choices mixed with salty, high-fat snack foods" (Sheryl Julian).

High values are more common in a skewed left distribution. Uniform Distribution. A common definition is as follows: a function f(x) is a unimodal function if for some value m, . As such, scores tend to form a cluster around these two values. A distribution with more than one mode is said to be bimodal, trimodal, etc., or in general, multimodal. In normal distributions, the mean, median, and mode will all fall in the same location. Bimodal literally means "two modes" and is typically used to describe distributions of values that have two centers. Figure 1. A common definition is as follows: a function f(x) . The two modes represent probability clusters. Designed for operation on either railroads or highways. The bimodal distribution has two peaks. Having two distinct statistical modes. The figure shows the probability density function (p.d.f. BIMODAL DISTRIBUTION By N., Sam M.S. Trimodal Mode A trimodal mode is a set of data that has three modes. A distribution with a single mode is said to be unimodal. We call distributions with a single peak "unimodal." "Modal" comes from the word "mode" - this makes sense when you consider that the peak of a distribution is also the score that appears most frequently.
