What is the difference between population and sample distribution?
Sampling distribution is the probability distribution of a given sample statistic. For example, the sample mean. We could take many samples of size k and look at the mean of each of those. The means would form a distribution and that distribution has a mean, a variance and standard deviation. Now the population only has one mean, so we can't do this. Population distribution can refer to how some quality of the population is distributed among the population.
In a multiple-choice question the correct answer will be found?
among the responses.
What is the difference between time series and regression analysis?
A time series is a sequence of data points, measured typically at successive points in time spaced at uniformed time intervals. Time series analysis comprises methods for analyzing time series data in order to extract meaningful statistics. Regression analysis is a statistical process for estimating the relationship among variables.
What is a diagram that shows relationships among sets of objects?
Venn Diagram
What are the main qualities of a good estimator?
A "Good" estimator is the one which provides an estimate with the following qualities:Unbiasedness: An estimate is said to be an unbiased estimate of a given parameter when the expected value of that estimator can be shown to be equal to the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn. Unbiasedness is a good quality for an estimate, since, in such a case, using weighted average of several estimates provides a better estimate than each one of those estimates. Therefore, unbiasedness allows us to upgrade our estimates. For example, if your estimates of the population mean µ are say, 10, and 11.2 from two independent samples of sizes 20, and 30 respectively, then a better estimate of the population mean µ based on both samples is [20 (10) + 30 (11.2)] (20 + 30) = 10.75.Consistency: The standard deviation of an estimate is called the standard error of that estimate. The larger the standard error the more error in your estimate. The standard deviation of an estimate is a commonly used index of the error entailed in estimating a population parameter based on the information in a random sample of size n from the entire population.An estimator is said to be "consistent" if increasing the sample size produces an estimate with smaller standard error. Therefore, your estimate is "consistent" with the sample size. That is, spending more money to obtain a larger sample produces a better estimate.Efficiency: An efficient estimate is one which has the smallest standard error among all unbiased estimators.The "best" estimator is the one which is the closest to the population parameter being estimated.
True or False When a population is in genetic equilibrium there is no genetic variation among individuals in that population?
True
The combined alleles of all the individuals in a population is what?
The entire collection of genes among a population is called the "gene pool".
What happens when a population is not evolving?
The hardy-Weinberg theorem is put into effect which describes an equillibrium among the individuals in a population and among the alleles that they share.
What is differential survival and reproduction among individuals of a population that vary in details of shared traits?
Natural Selection.
What are uniform spacing patterns in such plants as the creosote bush most often associated with?
antagonistic interactions among individuals in the population
True or false Darwin observed variations among individuals within a population but he did not realize that these variations were caused by selective breeding?
True, Darwin did realize that the observed variations among individuals within a population were caused by selective breeding. Although he did do a lot of great stuff. He wrote a book called The Origin of Species. You should check it out if you would like to find out the stuff that he did and what he found out about evolution. Either that or rent a book from a library about evolution.
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
What is the difference among www.in And www.com?
Traditionally, .com is a commercial domain (although individuals can register .com as well), and .in is a domain in India.
How does gene flow affect the fitness of population?
Gene flow within a population distributes mutations among the individuals. Immigration and emigration transport alleles into and out of a population's gene pool, thus affecting the result of natural selection.
How does two organism's join a population?
Although the dynamics and evolution of a single closed population are governed by its life history, populations of many species are not completely isolated and are connected by the movement of individuals (immigration and emigration) among them.
What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
A voluntary agreement among individuals to secure their rights and welfare by creating a government and abiding by its rules is called?
social contract
