Goes somewhat beyond the requirements for a passing grade.

3 pts

4 pts

Research Question
2 pts

The question chosen must be appropriate for the statistical methods studied in this course.

Poor

The question is not appropriate for the purposes of this project.
The question does not require the use of any of the strategies used in this class to answer it.
Fair

The question is not of interest to the class.
The question has already been studied in some depth in class.
The question can be answered either without the student collecting his/her own data or without conducting a hypothesis test
Good

The question posed has some interest to the student, but perhaps not to the class.
The question has been minimally touched upon in class but not studied in depth.
The question does not require the student to collect his/her own data but does require a hypothesis test to answer it
Excellent

Question posed is of substantial interest to the student and class. Question is original and has not been studied before in class.
Question requires the use of a data collection method and a hypothesis test in order to answer it
Hypothesis test
4 pts

Choose the correct hypothesis test to use based on your question/ data collected.

Poor

The test selected for the type of question posed and the data collected is incorrect; either the null hypothesis or the alternative hypothesis is not correct, or both are not correct. No identification of one-or two-tailed test.
Fair

The correct test is selected for the type of question posed and the data collected but the test is incorrectly named; either the null hypothesis or the alternative hypothesis is not correct. No identification of one- or two-tailed test.
Good

The correct test is selected for the type of question posed and the data collected but the test is not correctly named; the null and alternative hypotheses are correct. One- or two-tailed test may not be correctly identified.
Excellent

The correct test is selected for the type of question posed and the data collected; the test is correctly named; the null and alternative hypotheses are correct.
One- or two-tailed test is correctly identified.
Analysis
6 pts

Perform all the necessary calculations showing the correct graphs and outputs

Poor

None of the necessary calculations are shown; descriptive analysis is missing, graphs are missing.
Fair

Only one or two of the necessary calculations are shown; one or two calculations may not be complete.
The graphs are not complete or well-constructed.
Good

All necessary calculations are shown but may not be complete. Graphs and outputs are mostly clear.
Excellent

All necessary calculations are shown and complete.
Graphs and outputs are well-constructed and correct.
Decision
4 pts

Determine to reject or fail to reject your null hypothesis.

Poor

The decision made is incorrect, with respect to the null hypothesis, with no appropriate reference to either the size of the p-value or a pre-determined level of significance.
Fair

The decision made is incorrect, with respect to the null hypothesis, based on the size of the p-value and a pre-determined level of significance.
Good

The correct decision is made , but with respect to the alternative hypothesis when it should be with respect to the null hypothesis, based on the size of the p-value and a pre-determined level of significance.
Excellent

The correct decision is made with respect to the null hypothesis based on the size of the p-value and a pre-determined level of significance.
Conclusion and summary
2 pts

Determine your conclusion and summarize your findings.

Poor

The conclusion is incorrect based on the collected data, the p-value and the predetermined level of significance.
Fair

The conclusion is incorrectly stated with respect to the null hypothesis rather than the alternative hypothesis. The findings of the study/experiment are minimally summarized; there is no generalization of the findings to the appropriate population.
Good

The conclusion is correctly stated with respect to the alternative hypothesis. The findings of the study/experiment are not fully summarized or there is no generalization of the findings to the appropriate population.
Excellent

The conclusion is correctly stated with respect to the alternative hypothesis. The findings of the study/experiment are fully summarized and generalized to the appropriate population.
Formatting
1 pts

Construct the structure of the paper to match requirements

Poor

Paper is not written in APA format, past tense, third person. Sources are missing, font size incorrect.
Fair

Paper does not consistently follow APA format or guidelines for writing style. Sources are not sound or complete.
Good

Paper follows guidelines with minor errors.
Excellent

Paper follows guidelines with no errors.
Structure
1 pts

Paper contains the necessary sections

Poor

Paper does not clearly show the required sections and/or is not the required length.
Fair

Paper is divided into sections which don't follow the requirements.
Good

Excellent

Paper clearly shows the required sections and is the required length.
