t-test analysis

Here is my published screencast of my t-test indicating whether or not ethnicity impacts reading scores for 8th graders.

Null Hypothesis: There is NO relationship between reading scores and ethnicity on the 2013 National Assessment of Educational Progress.
Alternative Hypothesis:  There IS a relationship between reading scores and ethnicity on the 2013 National Assessment of Educational Progress. .

Here is my image of my excel spreadsheet annotated using Jing:

t-test Does Ethnicity Impact Reading Scores?

I ran a t-test comparing the scores of Whites and Hispanics (left table above), Whites and Blacks (middle table above) and Hispanics and Blacks (right table above). I computed the t-tests using the Data Analysis Tool on Excel assuming there were equal variances. The results of all comparisons indicated a P value of 0 which rejects the null hypothesis stated above.  In conclusion, there IS a significant impact on reading scores based on ethnicity.

APA Style for statistics:
When including statistics in written text, include enough information for the reader to understand the study.  Only include the table if it is absolutely necessary.  I would  use the wording in the above paragraph and I would reference the web site from which the data came (NAEP State Comparisons)
