1. ## Statistical hypothesis testing - Wikipedia

https://en.wikipedia.org/wiki/Statistical_hypothesis_testing

Variations and sub-classes. 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.

Hypothesis Testing. Selecting the appropriate comparison test can be challenging especially in the learning stages. A Six Sigma project manager should understand the formulas and computations within the commonly applied tests.

3. ## Multiple comparisons problem - Wikipedia

https://en.wikipedia.org/wiki/Multiple_comparisons_problem

In statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values. In certain fields it is known as the look-elsewhere effect.. The more inferences are made, the more likely erroneous inferences are to occur.

Hypothesis Testing, Statistical Significance, and Independent t Tests Hypothesis Testing and Statistical Significance When a hypothesis is tested by collecting data and comparing statistics from a sample with a predetermined value from a theoretical distribution, like the normal distribution, a researcher makes a decision about whether the null hypothesis should be retained or whether the …

Based on Theorem 2 of Chi-square Distribution and its corollaries, we can use the chi-square distribution to test the variance of a distribution.. Example 1: A company produces metal pipes of a standard length.Twenty years ago it tested its production quality and found that the lengths of the pipes produced were normally distributed with a standard deviation of 1.1 cm.

The null hypothesis in probability and statistics is the starting assumption that nothing other than random chance is operating to create the observed effect that you see in a particular set of data.

This is the first of three modules that will addresses the second area of statistical inference, which is hypothesis testing, in which a specific statement or hypothesis is generated about a population parameter, and sample statistics are used to assess the likelihood that the hypothesis is true.
