Distinguished - Successfully pools the individual causes of death into broader categories; reconstructs histograms of causes of death, and years of life lost, on the basis of the new categories; and compares and contrasts findings with Week One results. 

Proficient - Successfully pools the individual causes of death into broader categories, and reconstructs histograms of causes of death, and years of life lost, on the basis of the new categories. However, there is no comparison or contrast to the findings from the Week One assignment.

Basic - The individual causes of death were not pooled in a systematic manner.

Below Expectations - Recategorization of causes of death into broader categories was not accomplished.

Non-Performance - The reanalysis of the cause of death data on the basis of systemic categories is either nonexistent or lacks the components described in the assignment instructions.

Distinguished - Successfully computes and interprets chi-square statistics for assessing sex ratio differences in first-borns by race, and for assessing seasonality (differences by month) in birth rates.

Proficient -Successfully computes the chi-square statistics for assessing gender differences in first-borns by race, and for assessing seasonality (differences by month) in birth rates. However, the inferences drawn from these statistical tests isn’t altogether correct.

Basic - Correctly computes and interprets only one of the two required chi-square tests for assessing gender differences in first-borns by race, and for assessing seasonality (differences by month) in birth rates.

Below Expectations - Does not correctly compute either the chi-square statistic for assessing gender differences in first-borns by race, or the chi-square statistic for assessing seasonality (differences by month) in birth rates.

Non-Performance - The reanalysis of birth statistics to assess birth order in first-borns, and seasonality in births, is either nonexistent or lacks the components described in the assignment instructions.

Distinguished - Correctly calculates the score function from logistic regression for classifying individuals as cancer or normal, computes the operating characteristics of this decision rule (sensitivity, specificity, false positive and false negative rates, and accuracy), and comments on the suitability of this rule.

Proficient -The calculation of the score function is correct, but not all of the operating characteristic of the decision rule were correctly reported.

Basic - The calculation of the score function is correct, but the determination of the operating characteristics (sensitivity, specificity, false positive and false negative rates, and overall accuracy) are in error.

Below Expectations - The calculation of the score function was incorrect; hence the operating characteristics of the decision rule are in error.

Non-Performance - The analysis of the week 3 dataset by means of the logistic function classification scheme is either nonexistent or lacks the components described in the assignment instructions.

Distinguished - Correctly performs a t-test for assessing a period effect in the crossover clinical trial, and properly interprets the result.

Proficient - Correctly performs a t-test for assessing a period effect in the crossover clinical trial, but does not properly interpret the result.

Basic - Does not properly perform a t-test for assessing a period effect in the crossover clinical trial, but the interpretation of the t-test is correct.

Below Expectations - Does not properly perform a t-test for assessing a period effect in the crossover clinical trial.

Non-Performance - The assessment of a period effect in the crossover trial is either nonexistent or lacks the components described in the assignment instructions.

Distinguished -Correctly assesses whether the physiologic variables and IQ differ by gender by means of two sample t-tests, and determines whether IQ differs by birth order with means of a paired t-test.

Proficient - Correctly performs the paired t-test for assessing whether IQ differs by birth order, but not correctly assess gender differences in all of the physiologic variables.

Basic - Correctly assesses gender differences in some but not all of the physiologic variables, but does not assess whether IQ differs by birth order with a paired t test.

Below Expectations - Does not correctly perform any of the two sample t-tests or the paired t test.

Non-Performance - The reanalysis of the week 5 dataset is either nonexistent or lacks the components described in the assignment instructions.

Distinguished - Conclusions and related outcomes are logical and clearly reflect an informed evaluation and the ability to place evidence and perspectives discussed in priority order.

Proficient - Conclusions and related outcomes are logical and reflect an informed evaluation and the ability to place evidence and perspectives discussed in priority order.

Basic - Conclusions and related outcomes are identified and minimally reflect an informed evaluation and the ability to place evidence and perspectives discussed in priority order.

Below Expectations - Conclusions and related outcomes are not logical or reflective of an informed evaluation and the ability to place evidence and perspectives discussed in priority order.

Non-Performance - The assignment is either nonexistent or lacks the components described in the instructions.

Distinguished - Displays meticulous comprehension and organization of syntax and mechanics, such as spelling and grammar. Written work contains no errors and is very easy to understand.

Proficient - Displays comprehension and organization of syntax and mechanics, such as spelling and grammar. Written work contains only a few minor errors and is mostly easy to understand.

Basic - Displays basic comprehension of syntax and mechanics, such as spelling and grammar. Written work contains a few errors which may slightly distract the reader.

Below Expectations - Fails to display basic comprehension of syntax or mechanics, such as spelling and grammar. Written work contains major errors which distract the reader.

Non-Performance - The assignment is either nonexistent or lacks the components described in the instructions.

Distinguished - Accurately uses APA formatting consistently throughout the paper, title page, and reference page.

Proficient - Exhibits APA formatting throughout the paper. However, layout contains a few minor errors. 

Basic - Exhibits limited knowledge of APA formatting throughout the paper. However, layout does not meet all APA requirements. 

Below Expectations - Fails to exhibit basic knowledge of APA formatting. There are frequent errors, making the layout difficult to distinguish as APA.

Non-Performance - The assignment is either nonexistent or lacks the components described in the instructions.

Distinguished - The length of the paper is equivalent to the required number of correctly formatted pages. 

Proficient - The length of the paper is nearly equivalent to the required number of correctly formatted pages. 

Basic - The length of the paper is equivalent to at least three quarters of the required number of correctly formatted pages.

Below Expectations - The length of the paper is equivalent to at least one half of the required number of correctly formatted pages.   

Non-Performance - The assignment is either nonexistent or lacks the components described in the instructions.

Distinguished - Uses more than the required number of scholarly sources, providing compelling evidence to support ideas. All sources on the reference page are used and cited correctly within the body of the assignment.

Proficient - Uses the required number of scholarly sources to support ideas. All sources on the reference page are used and cited correctly within the body of the assignment.

Basic - Uses less than the required number of sources to support ideas. Some sources may not be scholarly. Most sources on the reference page are used within the body of the assignment. Citations may not be formatted correctly.
