Testing hypothesis Essay STEP 1: State the hypotheses. STEP 2: Set the criteria for a. STEP 3: Compute the test. STEP 4: Make a decision.
Hypothesis testing is a method of making decisions using data from scientific study. In statistics, a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone, according to pre-determined threshold probability, the significance level.
Hypothesis testing is defined as the statistical test used by the experienced statisticians to determine the population parameter. It also refers to the procedures used by the analysts to accept or reject the statistical hypothesis. It is used to infer the result of a hypothesis performed on a sample data from a large population.
Hypothesis Testing For this data set, our group have chosen to conduct a paired T-test. A t-test is a statistical test that compares the means of two groups of observations. For this instance, the data are classified into the groups: family income in Toronto, and family income in New York.

In this method, we test some hypothesis by determining the likelihood that a sample statistic could have been selected, if the hypothesis regarding the population parameter were true.
Start Unit test 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.

Definition: The Hypothesis Testing is a statistical test used to determine whether the hypothesis assumed for the sample of data stands true for the entire population or not. Simply, the hypothesis is an assumption which is tested to determine the relationship between two data sets.
