Distinguished - Performs the following correctly: selection of correct data, identification of data location, identification of the null and alternate hypotheses, identification of significance level, identification and justification of the test to use, decision rule, data set-up for the test, correct test outcome, answers to the questions, and a clear and accurate interpretation of the results.

Proficient - Performs the data identification and the six hypothesis steps correctly with no more than one error.

Basic - Performs the data identification and the six hypothesis steps correctly with no more than three errors.

Below Expectations - Performs the data identification and the six hypothesis steps correctly with than three errors.

Non-Performance - There is no response to Problem One, or it does not provide any correct responses to the question elements.

Total: 1.50

Distinguished - Performs all elements correctly: identifies the correct pairs to compare, calculates mean differences, identifies the correct t-value; calculates the correct +/- values; and correctly identifies the significantly different pairs of means.

Proficient - Has errors in only one area: identifies the correct pairs to compare, calculates mean differences, identifies the correct t-value; calculates the correct +/- values; and correctly identifies the significantly different pairs of means.

Basic - Has errors in only two or three areas: identifies the correct pairs to compare, calculates mean differences, identifies the correct t-value; calculates the correct +/- values; and correctly identifies the significantly different pairs of means.

Below Expectations - Has errors in four or five areas: identifies the correct pairs to compare, calculates mean differences, identifies the correct t-value; calculates the correct +/- values; and correctly identifies the significantly different pairs of means.

Non-Performance - There is no response to Problem Two, or it does not provide any correct responses to the problem’s elements.

Distinguished - Thoroughly concludes the implications of the analysis on the equal pay question and clearly and accurately identifies the statistical results that support the conclusion.

Proficient - Concludes the implications of the analysis on the equal pay question and identifies the statistical results that support the conclusion. Minor details are missing or inaccurate.

Basic - Partially concludes the implications of the analysis on the equal pay question and minimally identifies the statistical results that support the conclusion. Relevant details are missing or inaccurate.

Below Expectations - Attempts to conclude the implications of the analysis on the equal pay question and identify the statistical results that support the conclusion; however, significant details are missing and inaccurate.

Non-Performance - The conclusion and implications are either nonexistent or do not contain the components addressed in the assignment instructions.
