Mean and standard deviation for Age and associated Excel output table are not included. Hand calculations for the standard error of the mean are not included. Hand calculations for a 95% confidence interval for Age and SPSS output screenshots verifying the answer are not included. Interpretation of the confidence interval for age, explanation of the three pieces of information needed to calculate the confidence interval, and discussion of the age cut-off are not included. Surface errors are pervasive enough that they impede communication of meaning. Inappropriate word choice or sentence construction is used. Total Points 70.0 Less than Satisfactory (74.00%) Calculation of probability of an individual being 60 years or older, including associated hand calculations and screenshots, is incomplete or incorrect. Mean and standard deviation for Age and associated Excel output table are incomplete or incorrect. Hand calculations for the standard error of the mean are incomplete or incorrect. Hand calculations for a 95% confidence interval for Age and SPSS output screenshots verifying the answer are incomplete or incorrect. Interpretation of the confidence interval for age, explanation of the three pieces of information needed to calculate the confidence interval, and discussion of the age cut-off are incomplete or incorrect. Frequent and repetitive mechanical errors distract the reader. Inconsistencies in language choice (register) or word choice are present. Sentence structure is correct but not varied. Satisfactory (79.00%) Calculation of probability of an individual being 60 years or older, including associated hand calculations and screenshots, is partially complete and correct. Mean and standard deviation for Age and associated Excel output table are partially complete and correct. Hand calculations for the standard error of the mean are partially complete and correct. Hand calculations for a 95% confidence interval for Age and SPSS output screenshots verifying the answer are partially complete and correct. Interpretation of the confidence interval for age, explanation of the three pieces of information needed to calculate the confidence interval, and discussion of the age cut-off are included but lack details and supporting information. Some mechanical errors or typos are present, but they are not overly distracting to the reader. Correct and varied sentence structure and audience-appropriate language are employed. Good (87.00%) Calculation of probability of an individual being 60 years or older, including associated hand calculations and screenshots, is mostly complete and correct. Mean and standard deviation for Age and associated Excel output table are mostly complete and correct. Hand calculations for the standard error of the mean are mostly complete and correct. Hand calculations for a 95% confidence interval for Age and SPSS output screenshots verifying the answer are mostly complete and correct. Interpretation of the confidence interval for age, explanation of the three pieces of information needed to calculate the confidence interval, and discussion of the age cut-off are complete and include details and supporting information. Prose is largely free of mechanical errors, although a few may be present. The writer uses a variety of effective sentence structures and figures of speech. Excellent (100.00%) Calculation of probability of an individual being 60 years or older, including associated hand calculations and screenshots, is complete and correct. Mean and standard deviation for Age and associated Excel output table are complete and correct. Hand calculations for the standard error of the mean are complete and correct. Hand calculations for a 95% confidence interval for Age and SPSS output screenshots verifying the answer are complete and correct. Interpretation of the confidence interval for age, explanation of the three pieces of information needed to calculate the confidence interval, and discussion of the age cut-off are extremely thorough with substantial details and supporting information. Writer is clearly in command of standard, written, academic English. Comments Points Earned A local community organization was interested in learning about general health behaviors in the area and the relationships between health behaviors and environmental and social determinants.
