Students will practice t-test calculations using technology, just as they will be required to do so during examinations. 

Objectives

  • Students will discuss scenarios when best to use a t-test.
  • Students will practice writing their null and alternative hypotheses.
  • Students will decide between one and two tailed tests, finding the t-value and p-value with the handheld, and stating their conclusions.

Vocabulary

  •  t-test   
  • normally distributed       
  • variance
  • hypotheses     
  • pooled data 
  • p-value
 

About the Lesson

Students will be given several examples of data. They will do the following for each

example:

  • Write down the null and alternative hypotheses.
  • State whether the example is a one-tailed or a two-tailed test.
  • Using the handheld, students will find the t-value and   p-value for a 2 sample t-test at the 5% significance level.
  • Write down the conclusion to the test.
