relative frequency

relative frequency : In statistics the frequency of an event i is the number n i of times the event occurred in the experiment or the study. These frequencies are often graphically represented in histograms. We speak of absolute frequencies, when the counts n i themselves are given and of (relative) frequencies, when those are normalized by the total number of events: Taking the f i for all i and tabulating or plotting them leads to a frequency distribution. The relative frequency density of the occurrence of an event is the score divided by the total number of observations. For example: If the lower extreme of the class you are measuring the density of is 15 and the upper extreme of the class you are measuring is 30, given a relative frequency of 0.0625, you would calculate the frequency density for this class to be: In biology, relative frequency is the occurrence of a single gene in a specific species that makes up a gene pool. The limiting relative frequency of an event ove....   More from Wikipedia

relative frequency : 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..   More from Wikipedia

relative frequency : 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..

Question : what is relative frequency? Can someone give me an example?

Answer : Example The Bumbleton and Stickton village football teams have played each other 50 times. Bumbleton have won 10 times, Stickton have won 35 times, and the teams have drawn 5 times. We want to estimate the probability that Stickton will win the next match. So far, Stickton have won 35 out of the 50 matches. We can write this as a fraction, which is . This fraction isn't the probability of Stickton winning, but it is an estimate of that probability. We say that the relative frequency of Stickton winning is . Relative frequency We calculate the relative frequency of an outcome using this formula: We can estimate the probability of a particular outcome by calculating the relative frequency. The estimate of probability becomes more accurate if more trials are carried out...   More from Yahoo Answers

Question : Luke has a dice with 3 blue faces, 2 red faces and 1 yellow face. He rolls the dice 300 times. The reults are: BLUE-153 Red- 99 yellow-47 What is the relative frequency of throwing a blue?

Answer : Relative frequency is the frequency (amount of times an event took place) divided by the number of attempts where the event COULD have occured. Think of it like probability: number of ways a thing can happen (divided by) total number of outcomes In this case, the relative frequency of blue is 153 divided by 300 = 51% By the way, your data only adds up to 299 - not 300 - you might want to make sure...   More from Yahoo Answers
