Hypothesis Testing

This week we were assigned to take our data and hypothesis from last week and use a T Test to find out if our data is statistically significant. This was a little difficult for me at first. I watched the videos that our professor gave us, but I was still a little confused. Then I went to the discussion board and found a post from Cassity that really helped. From there I was able to complete the assigned tests. Below is a video of me completing one of my tests.

One thing that has changed from last week is that I had to change the wording of my hypothesis and null hypothesis.

Question 1
Does teaching status affect number of discussion posts?
Independent Variable
Teaching status
Dependent Variable
Number of discussion posts
Hypothesis
Teaching status does affect discussion posts.
Null Hypothesis
Teaching status does not affect discussion posts.

P value: 0.064723
Question 2
Does gender affect quiz score?
Independent Variable
Gender
Dependent Variable
Quiz score
Hypothesis
Gender does affect quiz score.
Null Hypothesis
Gender does not affect quiz score.

P value: 0.284535

For both of my questions, the p value is higher than .05. This means that the data is not statistically significant. I can say that teaching status does not affect discussion posts and gender does not affect quiz score.

This activity fits ISTE NETS T standard number three. We tested our hypothesis using Excel and this is digital age thinking. Research in teaching is important so that we can increase student learning and improve the profession.
