Homoscedasticity describes a situation in which the error term (that is, the noise or random disturbance in the relationship between the independent variables and the dependent variable) is the same across all values of the independent variables. Sciences, Culinary Arts and Personal 1. apparently reasonable and credible, and therefore convincing 2. given to or characterized by presenting specious arguments Familiarity information: PLAUSIBLE used as … The assumption of homoscedasticity (meaning same variance) is central to linear regression models. What does plausible mean in statistics? Stability is an important characteristic of plausible reasoning. Use these results to test the claim that men have a mean weight greater than 166.3 lb, which was the weight in the National Transportation and Safety Board’s recommendation.

Let these estimates be , where j={1,2,...m} for the m plausible values. Create your account. For example, if you have data on temperatures in your area and data on your electricity consumption, it's plausible that warmer temperatures will lead to more air-conditioning use and hence higher electricity use. Plausible reasoning is commonly based on appearances from perception. In this paper, we show that the marginal distribution of plausible values is a consistent estimator of the true latent variable distribution, and, furthermore, that convergence is monotone in an embedding in which the number of items tends to infinity. • PLAUSIBLE (adjective) The adjective PLAUSIBLE has 2 senses:. These terms include both probability and proportion. If your are interested in the details of the specific statistics that may be estimated via plausible values, you can see: In contrast, a proportion is also a type of probability. Statistics is an area of math that is used to measure the probability that a given event will occur or not. Mathematical techniques used for this include mathematical analysis, linear algebra, stochastic analysis, differential equation and measure-theoretic probability theory. 2 : superficially pleasing or persuasive a swindler … , then a quack, then a smooth, plausible … Hypothesis testing is the process that an analyst uses to test a statistical hypothesis. If your are interested in the details of the specific statistics that may be estimated via plausible values, you can see: men, we obtain these sample statistics: n = 40 and mean = 172.55 lb, and s = 26.33 lb. Rather than simply describe a set of data, inferential statistics seeks to infer something about a population on the basis of a statistical sample.One specific goal in inferential statistics involves the determination of the value of an unknown population parameter. statistical definition: 1. relating to statistics: 2. relating to statistics: 3. relating to statistics: . To interpret its value, see which of the following values your correlation r is closest to: Exactly –1. Depending on the t-test that you use, you can compare a sample mean to a hypothesized value, the means of two independent samples, or the difference between paired samples. In epidemiology and biomedicine, biological plausibility is the proposal of a causal association — a relationship between a putative cause and an outcome — that is consistent with existing biological and medical knowledge.. Making a t interval for paired data. Therefore, correlations are typically written with two key numbers: r = and p = . Conditions for valid t intervals. Services, Working Scholars® Bringing Tuition-Free College to the Community. There’s quite a big difference between ‘possible’ and ‘plausible’. Heteroscedasticity (the violation of homoscedasticity) is present when the size of the error term differs across values of an independent variable. Meaning of plausible. In statistics, the correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. Dictionary entry overview: What does plausible mean? plausible - apparently reasonable and valid, and truthful; "a plausible excuse" believable , credible - capable of being believed; "completely credible testimony"; "credible information" implausible - having a quality that provokes disbelief; "gave the teacher an implausible excuse" To estimate a target statistic using plausible values, Estimate the statistic once for each of m plausible values. Interestingly, the values for a percentage and a proportion are mathematically related. "|If something is said to be plausible, it means that that thing is "Possible and could've happened". A perfect downhill (negative) linear relationship […] The mean is the arithmetic average. Range provides provides context for the mean, median and mode. Conversely, to convert a percentage to a proportion, simply divide by 100. Plausible reasoning can be tested, and by this means, confirmed or refuted. plausible (adj) given to or characterized by presenting specious arguments. If the chance explanation can be ruled out, then the di erences seen in the study must be due to the e ectiveness of the treatment being studied. T-tests are statistical hypothesis tests that you use to analyze one or two sample means. ... Confidence interval for a mean with paired data. All rights reserved. There are several terms used in the field of statistics that tend to be associated with some confusion. Šwg/3»3;猲þPeqöŒ{³WÊóÝÎ{M#¶!¯;ƒ!ƒ6¶ƒ ÃfT©ÒÉS•Ä2«€ê—-{€B. Information and translations of plausible in the most comprehensive dictionary definitions resource on the web. Let these estimates be , where j={1,2,...m} for the m plausible values. ƒý†_@'˜‚?AÉ*3äÔnU Œüþ%N°XÓ! ; Calculate the average of the m estimates to obtain your final estimate: . The Challenge for Students Each year many AP Statistics students who write otherwise very nice solutions to free-response questions about inference don’t receive full credit because they fail to deal correctly with the assumptions and conditions. To communicate the probability, there are key terms that can be used to show the likeliness of an event happening. In this paper, we show that the marginal distribution of plausible values is a consistent estimator of the true latent variable distribution, and, furthermore, that convergence is monotone in an embedding in which the number of items tends to infinity. It estimates the amount by which the experimental intervention changes the outcome on average compared with the control. The p-value measures consistency between the results actually ob-tained in the trial and the \pure chance" explanation for those results. Plausible, specious describe that which has the appearance of truth but might be deceptive. Consequently, although an innocuous interpretation of the defendants' conduct may be plausible, that does not mean that the plaintiff's allegation that that conduct was culpable is not also plausible… Plausible values are based on student responses to the subset of items they receive, as well as on other relevant and available background information (Mislevy, 1991). The first, PV-W (W for “wrong”), is calculated by taking the average of the plausible values for each answer! The first, PV-W (W for “wrong”), is calculated by taking the average of the plausible values for each The alternative hypothesis is the one you would believe if the null hypothesis is concluded to be untrue.The evidence in the trial is your data and the statistics that go along with it. To see whether the mean is plausible or not, you simply have to see whether the mean is in the interval. Statistical significance is indicated with a p-value. We use this result to clarify some of the misconceptions that exist about plausible values, and also show how they can be used in the analyses of educational … Wiktionary (2.71 / 7 votes)Rate this definition: plausible deniability (Noun) The organization of a clandestine military operation in such a way that knowledge of its … It should be testable, either by experiment or observation. Mathematical statistics is the application of Mathematics to Statistics, which was originally conceived as the science of the state — the collection and analysis of facts about a country: its economy, and, military, population, and so forth. Inferential statistics gets its name from what happens in this branch of statistics. "It is plausible that a person will go to Mars before 2030. The mean describes an entire sample with a single number that represents the center of the data. The closer r is to zero, the weaker the linear relationship. Plausible values can be viewed as a set of special quantities generated using a technique called multiple imputations. Plausible deniability is the ability of people, typically senior officials in a formal or informal chain of command, to deny knowledge of or responsibility for any damnable actions committed by others in an organizational hierarchy because of a lack or absence of evidence that can confirm their participation, even if they were personally involved in or at least willfully ignorant of the actions. Definition of plausible in the Definitions.net dictionary. To convert a proportion to a percentage, simply multiply by 100. "It is plausible that Donald Trump will be the next president of the United States." plausible chance assignment alone can be as an explanation. The value of r is always between +1 and –1. To see whether the mean is plausible or not, you simply have to see whether the mean is in the interval. Usage: Plausible denotes that which seems reasonable, yet leaves distrust in the judgment.Specious describes that which presents a fair appearance to the view and yet covers something false.Specious refers more definitely to the act or purpose of false representation; plausible has more reference to the effect on the beholder or hearer. In this post, I show you how t-tests use t-values and t-distributions to calculate probabilities and test hypotheses. Plausible reasoning can be used to fill in implicit premises in incomplete arguments. The mean difference (more correctly, 'difference in means') is a standard statistic that measures the absolute difference between the mean value in two groups in a clinical trial. If the mean is in the interval, then it is a plausible value. Princeton's WordNet (0.00 / 0 votes)Rate this definition: plausible (adj) apparently reasonable and valid, and truthful. I'm pretty sure that "plausible" is used with its standard, non-technical meaning here, and refers to the mechanism by which your data is generated. You calculate the mean by adding up all of the observations and then dividing the total by the number of observations. A Simply put, it is the decimal form of a percentage. ; Calculate the average of the m estimates to obtain your final estimate: . Something is plausible if it’s credible or can be believed. The impact of violatin… A probability is often expressed as a percentage. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. If the mean is in the interval, then it is a plausible value. Use a 0.05 significance level, and the traditional method for the test. "a plausible liar". To estimate a target statistic using plausible values, Estimate the statistic once for each of m plausible values. Plausible deniability is the ability of people, typically senior officials in a formal or informal chain of command, to deny knowledge of or responsibility for any damnable actions committed by others in an organizational hierarchy because of a lack or absence of evidence that can confirm their participation, even if they were personally involved in or at least willfully ignorant of the actions.

Become a Study.com member to unlock this Definition of plausible "Plausible" means you really aren't sure whether something will happen, but you wouldn't be surprised if it did. The hypothesis is a statement, assumption or claim about the value of the parameter (mean, variance, median etc.). What does plausible mean in statistics? The person or thing that is plausible strikes the superficial judgment favorably; it may or may not be true: a plausible argument (one that cannot be verified or believed in entirely). It is claimed that μ is not 1800. When you construct a 95% confidence interval, it gives an interval with plausible values at 5%.
