What would best describe a bimodal distribution?

In statistics, a bimodal distribution is a probability distribution with two different modes, which may also be referred to as a bimodal distribution. These appear as distinct peaks (local maxima) in the probability density function, as shown in Figures 1 and 2.

Is the normal distribution is an example of a bimodal distribution?

A bimodal distribution has two peaks (hence the name, bimodal). They are usually a mixture of two unique unimodal (only one peak, for example a normal or Poisson distribution) distributions, relying on two distributed variables X and Y, with a mixture coefficient α.

What does bimodal distribution mean in psychology?

a set of scores with two peaks or modes around which values tend to cluster, such that the frequencies at first increase and then decrease around each peak.

What is the example of bimodal?

Statistical Glossary Bimodal literally means “two modes” and is typically used to describe distributions of values that have two centers. For example, the distribution of heights in a sample of adults might have two peaks, one for women and one for men.

What is a bimodal distribution in biology?

a statistical pattern in which the frequencies of values in a sample have two distinct peaks, even though parts of the distribution may overlap. For example, the sexual differences between men and women for such characters as height and weight produce a bimodal distribution.

Can a bimodal distribution be skewed?

Bimodal histograms can be skewed right as seen in this example where the second mode is less pronounced than the first. Distributions having more than two modes are called multi-modal.

What is bimodal in math?

bimodal – of a distribution; having or occurring with two modes. statistics – a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters. unimodal – having a single mode.

What is a multimodal distribution?

Multimodal Distribution. Multimodal distribution is a distribution that has multiple modes (thus two or more “peaks”). Multimodality of the distribution in a sample is often a strong indication that the distribution of the variable in population is not normal.

What is bimodal data?

A data set is bimodal if it has two modes. This means that there is not a single data value that occurs with the highest frequency. Instead, there are two data values that tie for having the highest frequency.

What is a bimodal graph?

A bimodal graph illustrates a bimodal distribution, which is itself defined as a continuous probability distribution with two modes.
