Exam 12: Teafor Two Again: Tests Between the Means of Related Groups

Dr.Moo's student,Mr.Grass,is working on a research project but is unsure of how to analyze his data.He would like to find out if goats produce more milk after going through a new relaxation program for goats,the Goatness Gracious program.He measured the amount of goat's milk produced before Goatness Gracious and would like to compare this with the amount of goat's milk produced after Goatness Gracious.Identify the type of test he would need to use to determine this,and explain your answer.

You run a t test and find that your results indicate that t₍₃₈₎ = 1.13,p > 0.05.You determine that you should ______.

In the equation t₍₇₈₎ = 1.03,p < 0.01,what does 1.03 represent?

In the following,what is the number 5.5015: t₍₅₈₎ = 5.015,p < 0.01?

To be 99% confident you have not committed a Type I error,at what level should the p value be set?

Early education researchers can match two classrooms from different school districts and analyze their hypothesis with a dependent-samples t test,even if they are not careful about the characteristics of each classroom.

How many observations are there for each case in a t test for dependent samples?

In the equation t₍₇₈₎ = 1.03,p < 0.01,what does 78 represent?

In the equation t₍₇₈₎ = 1.03,p < 0.01,what does t represent?

In running a dependent-sample t test,how many subjects were there in the group based on the following: t₍₅₈₎ = 5.015,p < 0.01?

When calculating a dependent-samples t test,the order in which you input the posttest score and pretest score can change the t value.If you input the pretest first,the obtained value will be ______.

If your degrees of freedom is 98,your sample size when conducting a t test for dependent means must be ______.

If you want to examine the same group of individuals in two different times,which statistical technique should you select?

In the following,what are the degrees of freedom: t₍₅₈₎ = 5.015,p < 0.01?

The t test for dependent means is used when you have ______.

Interpret,in words,what it means for a research question that a null hypothesis was rejected.

When a researcher matches participants from different counseling graduate programs on variables such as age,gender,and a measure of multicultural understanding,the researcher can use a dependent-samples t test in the study.

Dr.Moo would like to find out if there was a significant difference between her patients' anxiety scores before and after they completed a yoga program.What is the appropriate test to run?

In a t-test for dependent means,the research hypothesis could look like this:
