Welcome and Thanks for using Just Answer.

Please note that although we can keep the scenario somewhat the same for the t test, 1-way anova and 2- way anova, the null hypotheses can't remain the same because a t- test is used for testing 2 groups while an anova is used for testing 3 or more groups.

Perhaps you are asking for an example of creating null hypotheses for a t-test, 2-way anova and 3-way anova using the same scenario?

Let me know.

Thanks.

Upon reading your question again, I think the problem is indeed asking to keep the situation same and creating 3 different null hypotheses.

I am working on your question and will post the answer shortly.

Thanks.

Yes--I believe that you are correct and that is what she wants. Below is an example of what she seems to be looking for, but I (obviously) have to come up with my own and I am so lost.

Research Question:

Does stress affect a person’s heart rate?

I created a t-test alternate and null hypothesis from that research question.

T-Test:

Alternate Hypothesis:

Stress raises the heart rate level.

Null T-test Hypothesis:

Stress does not have an affect on heart rate levels.

IV = stress (stress level can be manipulated)

DV = heart rate (the manipulation of stress changes rate rate levels)

I then created a one-way ANOVA alternate and null hypothesis.

One-Way ANOVA:

*one IV w/multiple categories and one DV

Alternate Hypothesis:

Different types of stress raises the rate heart levels to varying levels.

Null One-Way ANOVA Hypothesis:

Different types of stress have the same or no affect on heart rate levels.

IV = different types of stress ( i.e. relationships, family, work, financial issues, etc.)

DV = heart rate (rates from the different types of stress)

Finally, I created a two-way ANOVA alternate and null hypothesis.

Two-Way ANOVA :

*two IV w/multiple categories and one DV

Alternate Hypothesis:

Heart rate levels are affected by the sex of the individual and/or the type of stress they have.

Null Two-Way Hypothesis:

Different types of stress in men and/or women have the same or no affect on heart rate levels.

IV = different types of stress ( i.e. relationships, family, work, financial issues, etc.) and sex of person (i.e. male, female)

DV = heart rate (rates from the different types of stress)
