frequency distribution

frequency distribution : In statistics, a frequency distribution is a tabulation of the values that one or more variables take in a sample. Univariate frequency distributions are often presented as lists ordered by quantity showing the number of times each value appears. For example, if 100 people rate a five-point Likert scale assessing their agreement with a statement on a scale on which 1 denotes strong agreement and 5 strong disagreement, the frequency distribution of their responses might look like: This simple tabulation has two drawbacks. When a variable can take continuous values instead of discrete values or when the number of possible values is too large, the table construction is cumbersome, if it is not impossible. A slightly different tabulation scheme based on the range of values is used in such cases. For example, if we consider the heights of the students in a class, the frequency table might look like below. A Frequency Distribution shows us a summarized grouping of data divided into....   More from Wikipedia

frequency distribution : Several techniques can be used to move signals in the time-frequency distribution. Similar to computer graphic techniques, signals can be subjected to horizontal shifting, vertical shifting, dilation (scaling), shearing, and rotation. These techniques can help to save the bandwidth with proper motions..   More from Wikipedia

frequency distribution : Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. See also: Plants & Animals Evolutionary Biology Life Sciences Genetics Biochemistry Research Biology Zoology Usually it is expressed as a proportion or a percentage. In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool. The frequencies of all the alleles of a given gene often are graphed together as an allele frequency distribution histogram. Population genetics studies the different "forces" that might lead to changes in the distribution and frequencies of alleles - in other words, to evolution. Besides selection, these forces include genetic drift, mutation and migration..
