false positives and false negatives. In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (a "false positive"), probability of type 1 error while a type II error is incorrectly retaining a false null hypothesis type 3 error (a "false negative").[1] More simply stated, a type I error is detecting an effect that is not present,

Most commonly it is a statement that the phenomenon being studied produces no effect or makes no difference. An example of a null hypothesis is the statement "This diet has no effect on people's weight." Usually, an experimenter frames a null hypothesis with the intent of rejecting it: that is, intending to run an experiment which produces data that shows that the phenomenon under study does make a difference.[2] In some cases there is a specific alternative hypothesis that is opposed to the null hypothesis, in other cases the alternative hypothesis is not explicitly stated, or is simply "the null hypothesis is false" – in either event, this is a binary judgment, but the interpretation differs and is a matter of significant dispute in statistics. A typeI error (or error of the first kind) is the incorrect rejection of a true null hypothesis. Us

The statistical practice of hypothesis testing is widespread not only in statistics, but also throughout the natural and social sciences. When we conduct a hypothesis test there a couple of things that could go wrong. There are two kinds of errors, which by design http://statistics.about.com/od/Inferential-Statistics/a/Type-I-And-Type-II-Errors.htm cannot be avoided, and we must be aware that these errors exist. The errors are given the quite pedestrian names of type I and type II errors. What are type I and type II errors, and how we distinguish between them? Briefly:Type I errors happen when we reject a true null hypothesis.Type II errors happen when we fail to reject a false null hypothesis.We will explore more background behind these types of errors with the goal of understanding these statements.Hypothesis TestingThe process of hypothesis testing can seem to be quite varied with a multitude of test statistics. But the general process is the same. Hypothesis testing involves the statement of a null hypothesis, and the selection of a level of significance. continue reading below our video How Does Color Affect How You Feel? The null hypothesis is either true or false, and represents the default claim for a treatment or procedure. For example, when examining the effectiveness of a drug, the null hypothesis would be that the drug has no effect on a disease.After formulating the null hypothesis and choosing a level of significance, we ac

Instances of Error objects are thrown when runtime errors occur. The Error object can also be used as a base object for user-defined exceptions. See below for standard built-in error types. Syntax new Error([message[, fileName[, lineNumber]]]) Parameters message Optional. Human-readable description of the error. fileName Optional. The value for the fileName property on the created Error object. Defaults to the name of the file containing the code that called the Error() constructor. lineNumber Optional. The value for the lineNumber property on the created Error object. Defaults to the line number containing the Error() constructor invocation. Description Runtime errors result in new Error objects being created and thrown. This page documents the use of the Error object itself and its use as a constructor function. For a

[closed] up vote 1 down vote favorite I guess I asked the question in the title. Basically, when it comes to using the wrong form of a word (to instead of too, there instead of they're, etc.), what kind of error is this considered? Grammar, spelling, syntax, semantic, orthographic. Thanks!

If you're dealing with writing, it's a spelling problem. Or error. Most people don't care how they're spelled; since it doesn't make any difference in speech, it must not be anything important, or we wouldn't understand speech. And of course we do, much more easily than writing. –John Lawler Mar 8 '15 at 4:21 Don't you get annoyed by people who can't differentiate between you're vs your, their vs there vs they're ! ! !
