Student T-test and Null Hypothesis

What is a student t-test

A statistical test used to determine if there is a significant difference between the means of two groups

What is the critical value

The value against which you compare the calculated t-statistic to decide whether to reject the null hypothesis

What is usually the critical value for data stes

0.05

What is a null hypothesis

A statement saying there is no effect or difference and is a starting point for testing

What would happen if the student t-test has a value above the normal critical value

The null hypothesis is rejected and we say there is a significant difference between the means

What would happen if the student t-test has a value below the normal critical value

The null hypothesis is accepted and we say there isnt a significant difference between the means
