Unit 12: Significance tests (hypothesis testing)
About this unit.
Significance tests give us a formal process for using sample data to evaluate the likelihood of some claim about a population value. Learn how to conduct significance tests and calculate p-values to see how likely a sample result is to occur by random chance. You'll also see how we use p-values to make conclusions about hypotheses.

Hypothesis Testing
This page looks at Hypothesis testing. Topics include null hypothesis, alternative hypothesis, testing and critical regions.
The parameters of a distribution are those quantities that you need to specify when describing the distribution. For example, a normal distribution has parameters μ and σ 2 and a Poisson distribution has parameter λ.
If we know that some data comes from a certain distribution, but the parameter is unknown, we might try to predict what the parameter is. Hypothesis testing is about working out how likely our predictions are.
The null hypothesis , denoted by H 0 , is a prediction about a parameter (so if we are dealing with a normal distribution, we might predict the mean or the variance of the distribution).
We also have an alternative hypothesis , denoted by H 1 . We then perform a test to decide whether or not we should reject the null hypothesis in favour of the alternative.
Suppose we are given a value and told that it comes from a certain distribution, but we don"t know what the parameter of that distribution is.
Suppose we make a null hypothesis about the parameter. We test how likely it is that the value we were given could have come from the distribution with this predicted parameter.
For example, suppose we are told that the value of 3 has come from a Poisson distribution. We might want to test the null hypothesis that the parameter (which is the mean) of the Poisson distribution is 9. So we work out how likely it is that the value of 3 could have come from a Poisson distribution with parameter 9. If it"s not very likely, we reject the null hypothesis in favour of the alternative.
Critical Region
But what exactly is "not very likely"?
We choose a region known as the critical region . If the result of our test lies in this region, then we reject the null hypothesis in favour of the alternative.

A hypothesis test is carried out at the 5% level of significance to test if a normal coin is fair or not. (i) Describe what the population parameter could be for the hypothesis test. (ii) State whether the hypothesis test should be a one-tailed test or a two-tailed test, give a reason for your answer. (iii)
A hypothesis test is the means by which we generate a test statistic that directs us to either reject or not reject the null hypothesis. The test statistic is a "summary" of the collected data, and should have a sampling distribution specified by the null hypothesis. A Level AQA Edexcel OCR.

The four steps of hypothesis testing: Step 1: We state the Hypothesis. We start by assuming that the hypothesis or claim we are testing is true. This is stated in the null hypothesis. Step 2: Set the criteria for a decision. To set the criteria for a decision, we state the level of significance for a test.
