Statistical significance test A predecessor to the statistical hypothesis test see the Origins section. An experimental result was said to be statistically significant if a sample was sufficiently inconsistent with the null hypothesis. This was variously considered common sense, a pragmatic heuristic for identifying meaningful experimental results, a convention establishing a threshold of statistical evidence or a method for drawing conclusions from data. The statistical hypothesis test added mathematical rigor and philosophical consistency to the concept by making the alternative hypothesis explicit. The term is loosely used for the modern version which is now part of statistical hypothesis testing. Conservative test A test is conservative if, when constructed for a given nominal significance level, the true probability of incorrectly rejecting the null hypothesis is never greater than the nominal level. Exact test A test in which the significance level or critical value can be computed exactly, i.

In some contexts this term is restricted to tests applied to categorical data and to permutation tests , in which computations are carried out by complete enumeration of all possible outcomes and their probabilities. A statistical hypothesis test compares a test statistic z or t for examples to a threshold. The test statistic the formula found in the table below is based on optimality. For a fixed level of Type I error rate, use of these statistics minimizes Type II error rates equivalent to maximizing power. The following terms describe tests in terms of such optimality: Most powerful test For a given size or significance level, the test with the greatest power probability of rejection for a given value of the parameter s being tested, contained in the alternative hypothesis.

A test with the greatest power for all values of the parameter s being tested, contained in the alternative hypothesis. Common test statistics[ edit ] Main article: Test statistic Variations and sub-classes[ edit ] Statistical hypothesis testing is a key technique of both frequentist inference and Bayesian inference , although the two types of inference have notable differences. Statistical hypothesis tests define a procedure that controls fixes the probability of incorrectly deciding that a default position null hypothesis is incorrect.

The procedure is based on how likely it would be for a set of observations to occur if the null hypothesis were true. Note that this probability of making an incorrect decision is not the probability that the null hypothesis is true, nor whether any specific alternative hypothesis is true. This contrasts with other possible techniques of decision theory in which the null and alternative hypothesis are treated on a more equal basis. Other approaches to decision making, such as Bayesian decision theory , attempt to balance the consequences of incorrect decisions across all possibilities, rather than concentrating on a single null hypothesis. A number of other approaches to reaching a decision based on data are available via decision theory and optimal decisions , some of which have desirable properties.

Hypothesis testing, though, is a dominant approach to data analysis in many fields of science. Extensions to the theory of hypothesis testing include the study of the power of tests, i. Such considerations can be used for the purpose of sample size determination prior to the collection of data. Early use[ edit ] While hypothesis testing was popularized early in the 20th century, early forms were used in the s. Modern origins and early controversy[ edit ] Modern significance testing is largely the product of Karl Pearson p-value , Pearson's chi-squared test , William Sealy Gosset Student's t-distribution , and Ronald Fisher " null hypothesis ", analysis of variance , " significance test " , while hypothesis testing was developed by Jerzy Neyman and Egon Pearson son of Karl.

Ronald Fisher began his life in statistics as a Bayesian Zabell , but Fisher soon grew disenchanted with the subjectivity involved namely use of the principle of indifference when determining prior probabilities , and sought to provide a more "objective" approach to inductive inference. Neyman who teamed with the younger Pearson emphasized mathematical rigor and methods to obtain more results from many samples and a wider range of distributions.

Fisher popularized the "significance test". He required a null-hypothesis corresponding to a population frequency distribution and a sample. His now familiar calculations determined whether to reject the null-hypothesis or not. Significance testing did not utilize an alternative hypothesis so there was no concept of a Type II error. The p-value was devised as an informal, but objective, index meant to help a researcher determine based on other knowledge whether to modify future experiments or strengthen one's faith in the null hypothesis.

They initially considered two simple hypotheses both with frequency distributions. They calculated two probabilities and typically selected the hypothesis associated with the higher probability the hypothesis more likely to have generated the sample. Their method always selected a hypothesis. It also allowed the calculation of both types of error probabilities.

The defining paper [35] was abstract. Mathematicians have generalized and refined the theory for decades. World War II provided an intermission in the debate. The dispute between Fisher and Neyman terminated unresolved after 27 years with Fisher's death in Neyman wrote a well-regarded eulogy. Great conceptual differences and many caveats in addition to those mentioned above were ignored. Neyman and Pearson provided the stronger terminology, the more rigorous mathematics and the more consistent philosophy, but the subject taught today in introductory statistics has more similarities with Fisher's method than theirs. Sometime around , [42] in an apparent effort to provide researchers with a "non-controversial" [44] way to have their cake and eat it too , the authors of statistical text books began anonymously combining these two strategies by using the p-value in place of the test statistic or data to test against the Neyman—Pearson "significance level".

It then became customary for the null hypothesis, which was originally some realistic research hypothesis, to be used almost solely as a strawman "nil" hypothesis one where a treatment has no effect, regardless of the context. The null need not be a nil hypothesis i. These define a rejection region for each hypothesis. If the result is "not significant", draw no conclusions and make no decisions, but suspend judgement until further data is available.

If the data falls into the rejection region of H1, accept H2; otherwise accept H1. Note that accepting a hypothesis does not mean that you believe in it, but only that you act as if it were true. The usefulness of the procedure is limited among others to situations where you have a disjunction of hypotheses e. Early choices of null hypothesis[ edit ] Paul Meehl has argued that the epistemological importance of the choice of null hypothesis has gone largely unacknowledged.

When the null hypothesis is predicted by theory, a more precise experiment will be a more severe test of the underlying theory. When the null hypothesis defaults to "no difference" or "no effect", a more precise experiment is a less severe test of the theory that motivated performing the experiment. He states: "it is natural to conclude that these possibilities are very nearly in the same ratio". Thus Laplace's null hypothesis that the birthrates of boys and girls should be equal given "conventional wisdom".

He uses as an example the numbers of five and sixes in the Weldon dice throw data. Here the null hypothesis is by default that two things are unrelated e. If the "suitcase" is actually a shielded container for the transportation of radioactive material, then a test might be used to select among three hypotheses: no radioactive source present, one present, two all present. The test could be required for safety, with actions required in each case. The Neyman—Pearson lemma of hypothesis testing says that a good criterion for the selection of hypotheses is the ratio of their probabilities a likelihood ratio.

A simple method of solution is to select the hypothesis with the highest probability for the Geiger counts observed. The typical result matches intuition: few counts imply no source, many counts imply two sources and intermediate counts imply one source. Notice also that usually there are problems for proving a negative. Null hypotheses should be at least falsifiable. Neyman—Pearson theory can accommodate both prior probabilities and the costs of actions resulting from decisions. The latter allows the consideration of economic issues for example as well as probabilities. A likelihood ratio remains a good criterion for selecting among hypotheses. The two forms of hypothesis testing are based on different problem formulations. In the view of Tukey [51] the former produces a conclusion on the basis of only strong evidence while the latter produces a decision on the basis of available evidence.

Statistical Hypothesis Testing - Wikipedia
While the two tests seem quite different both mathematically and philosophically, later developments lead to the opposite claim. Consider many tiny radioactive sources. The hypotheses become 0,1,2, There is little distinction between none or some radiation Fisher and 0 grains of radioactive sand versus all of the alternatives Neyman—Pearson. The major Neyman—Pearson paper of [35] also considered composite hypotheses ones whose distribution includes an unknown parameter. An example proved the optimality of the Student's t-test, "there can be no better test for the hypothesis under consideration" p Neyman—Pearson theory was proving the optimality of Fisherian methods from its inception. Fisher's significance testing has proven a popular flexible statistical tool in application with little mathematical growth potential.
