Myopia and Later Physical Activity in Adolescence

Critically appraise of the statistical material in this paper against items 10, 12-17 of the STROBE checklist. Present your review as a 400-500 word (approx.) report.

Notes:

Only review the provided paper Deere et al, 2009. Do not read any other papers.
Restrict your review to how well Deere et al have documented their statistical methods – that is, items 10, 12-17 of STROBE only. You may not have to address every item; just describe the major strengths and weaknesses of the authors’ descriptions of their statistical methods and results.
For each important STROBE item:

state whether you believe the STROBE item is met or not,

support your judgment with proof or examples from the paper, and

describe why this inclusion or exclusion is important / how it will impact on the reader’s understanding and decision making.

The 400-500 words is a guideline not a rule. There are no penalties for exceeding this guideline.
There are no marks for adding a reference list. Referencing is optional.

Question 2 )  Note: Students will get different answers as the data sets differ.

Using the data set assigned to you for your Assignments address the following research question:

Does myopia status predict sedentary hours per week after correcting for age in the population of young adult Australians?

Notes:

You should only use the variables ‘sed’, ‘myopia’ and ‘age’.
Correcting for ‘age’ is just including ‘age’ in the regression model.  When age is in the model all other variables are corrected for it.
Do report the results of your descriptive analyses

Well labelled graphs can be copied from R Commander

Summary statistics and tables should be manually typed

Summarise the main findings of your descriptive analyses in words and describe how these findings inform your expectations and interpretation of the more complex models.

Do report the results of your statistical inference and/or regression models

Any fitted regression models should be manually typed and described in the text.

Any hypothesis tests should contain all relevant information (use the 5 step method to be sure)

Any other results such as confidence intervals should be manually typed and described in the text.

Summarise the main findings of your regression model and statistical inference in one or two paragraphs.

Do remember to answer the research question

Write a final paragraph which summarises the key findings of your analysis and your answer to the research question.

Do check the Learning Guide for the marking criteria
Do write your answers yourself and keep them private.
