DTN304 Assessment 2: Data cleaning and analysis
Student ID:
[Use this template to format your assignment. Instructions are in bold and Extra tips are in italics. Make sure to delete both of these (and this section in the square brackets) before submitting your assessment.]
Research question and objectives
Instructions
State the research question you have chosen
Describe objectives of the study. Is this a comparison question or a question about associations?
Data cleaning
Instructions:
Use simple descriptions and dot points to describe what you did, so that someone who is not familiar with the data can understand
Report any changes you made to the data using IDs of the participants.
Report (using IDs) and justify any management of errors
Extra Tips:
Data cleaning should mainly refer to the variables that are most relevant to your selected research question, but you should have checked for and fixed errors also in the rest of the variables that you present in your descriptive tables further down.
Change and report (using IDs with respective variable name) missing information where a correct response could be ascertained or assumed with justification.
Delete and report (using IDs with respective variable name) invalid data if there are no means of determining the correct value.
Leave the missing values blank or replace them with some explicit missing value code (for example, 999 or 9999). Dont forget to report changes using IDs and variable names.
Change and report (using IDs) invalid or unusual data (for example BMI which can be corrected using height and weight) if a correct response could be ascertained or assumed with justification.
Check outliers if any, using tables of minimum and maximum values and box and whisker plots. Dont forget to report them using IDs and variable names.
Variables might need to be recoded to create new ones that fit within the analytic needs of the selected research question. Report them along with the details.
Descriptive analysis
Instructions
Describe demographics of sample
Describe method to determine distribution (normality) of the data
Show appropriate summary statistics (e.g. mean and standard deviation or median and interquartile range)
Describe distribution (normality) of the data
Extra Tips:
Describe the sample based on demographic and anthropometric characteristics, dietary intake (mainly focusing on energy intake and macronutrients, i.e. carbs, total fat and protein intake) as well as those variables that are relevant to the selected research question.
This is strictly a descriptive part of the assignment where you need to describe your sample using text (Tables will be provided at the following section).
You need to show that you have checked the distribution of the continuous variables that are relevant to the question you have chosen. Have a look and report on the results (P-value) from the Kolmogorov-Smirnov normality test and also the histograms in order to be able to identify the normality of the distribution of the continuous variables and decide whether you should present these variable as Mean (SD) or as Median (IQR). You can also check the histograms, which you can include (as pictures/attachments) in the Presentation of results SPSS results section further down.
Presentation of results tables/figures/graphs
Instructions
Present any tables/figures/graphs you have made here (e.g. demographics/participants characteristics table)
Extra Tips:
This section should include Tables and/or graphs presenting demographic, participants characteristics and anthropometric characteristics, dietary intake (mainly focusing on energy intake and macronutrients, i.e. carbohydrates, total fat and protein intake) as well as those variables that are relevant to your selected research question.
Include an informative and detail title for all Tables and Figures/Graphs. Use footnotes to define acronyms used and to include other relevant information.
Continuous data should be presented as Mean (SD) OR as Median (IQR) depending on the normality, while categorical data as percentage (%) and counts (n).
Presentation of results SPSS outputs
Instructions
Present relevant SPSS results here as images (copy as images and paste here with appropriate label)
These may include histograms or results of normality tests
The results shown here should match the results in the descriptive analysis section and should be related to the chosen research questions
Extra Tips:
This section should include pictures/images from SPSS related to normality-test templates (i.e. tables presenting the Kolmogorov-Smirnov P-value), tables with %, mean (SD), Median (IQR, histograms and any other part of the SPSS outputs that is relevant to the data presented in the previous 2 sections (i.e. Descriptive analysis and Presentation of results tables/figures/graphs).
Plan for inferential analysis
Instructions
Based on the results above, state what inferential analysis/analyses you intend to carry out to answer your research question and complete your Research Poster (due Week 12)?
Extra Tips:
It is suggested to have a narrative on why you have chosen specific inferential statistical analyses tests as it demonstrates your understanding of statistics.
References
Instructions
Insert references here, using APA 7th style
Extra Tips:
It is not necessary to provide references. However, if you do, they should be cited in the text and presented using the APA 7th style.
Formatting notes:
Do not change the headings or font size in this template
Do not exceed 6 pages in total
Extra Tip:
Tables can use a font size that is smaller than 12pt, but not smaller than 8pt.
