Neither topic/question nor background is not stated.

Both the topic/questions and the background provided are flawed in at least one area.
OR
Either topic/question or background is missing.

The topic/question is flawed in either one of the areas: clearly stated or appropriateness for an abservational study.
OR
The background provided fails to provide support to this topic/question or is irrelevent to student's lives.

The topic/question selected is clearly stated and is appropriate for an observational study. The background provided gives adequate motivation for the group's choice of this topic/question and is somewhat relevent to student's lives.

The topice/question selected is clearly stated and is appropriate for an observational study. The background provided gives strong motivation for the group's choice of this topic/questions and its relevence to student's lives.

The randomization is flawed in all three area - labeling, number selection , and results
OR
Method is missing from report.

There is some flaw in the randomization procedure itself. Some aspect of the randomization-labeling, number selction, or results is completely correct.

The randomization process includes all three components listed at the right but the randomization process does not match the chosen sampling procedure.
OR
The randomization process matches the chosen sampling procedure, but the clarity of communication would prevent easy replication of this randomization, in spite of it being correctly designed and implemented.

The randomization process includes all three components listed at the right. However, clarity of communication would prevent easy replication of thei randomization. The randomization process matches the chosen sampling procedure.

The randomization process includes a clear and correct labeling of subjects, a description of the number selection process (random number table or calculator), and the results of the randomization (i.e. the numbers and subjects chosen). In addition the randomization process matches the chosen sampling procedure.

Original data is not available for review and the data is not tabulated appropriately.

Original data are unavailable for review but the data is summarized partially correct in a table.
OR
Original data are available for review but the table is not accurate.

Original data are unavailable for review but the data is summarized neatly, accurately and are clearly labeled.
OR
Original data are available for review, but there is a major flaw in the presentation of the data (but not in the accuracy of the tally).

Original data are availabe for review and summarized in appropriate table form. The tables however minor errors, sloppy, or not clearly labeled.

Original data are available for review and are summarized in an appropriate table form. Tables are neat, clearly labeled and accurate.

Interpretations and generalizations are missing.

Interpretations are attempted but are inadequate. Generalizations concerning the population of interest are omitted.

Interpretations of the graphical and numberical summaries have serious errors/omissions. In addition, an attempt is made at addressing generalization concerning the population of interest.

Interpretations of the graphical and numberical summaries have minor errors or omissions. In addition some generalizations concerning the population of interst are identify.

Interpretations of the graphical and numerical summaries are thorough and accurate. In addition, generalizations concerning the population of interest are identified.

The confidence statements fails in all of the following areas: applies to the population, correct confidence level, correct calculation of the margin of error, or understandability.

The confidence statements fails in threee of the following areas: applies to the population, correct confidence level, correct calculation of the margin of error, or understandability.

The confidence statements fails in two of the following areas: applies to the population, correct confidence level, correct calculation of the margin of error, or understandability.

The confidence statements fails in one of the following areas: applies to the population, correct confidence level, correct calculation of the margin of error, or understandability.

The confidence statement applies to the population, gives the correct confidence level, has a correctly calculated margin of error and is understandable.
