Week 8¶

Analysis Check-In¶

➤ This week we will reflect on the analyes that have, and will be, performed.

Before Class¶

Project Progress¶

👥 Meet with your group and compile a project draft. There should just be one document per group. You may e-mail it or send via Slack. It should include the following:

Background and Scope¶

Clearly outline the research questions posed by your investigator.
For each question, specify the key variables from the dataset that will be used to address it.
If applicable, briefly describe the study design and/or data source, to contextualize how the questions can be answered.

Data and Design¶

Summarize the unit of observation (e.g., participant, procedure, visit, time period) and the total number of observations available.
Describe the extent of missing data and any preliminary strategies for handling it (e.g., listwise deletion, pairwise deletion, imputation, sensitivity analysis).
Discuss variables of concern (e.g., input errors, unclear coding) and note any data cleaning steps performed.
Present summary statistics that describe the main variables (tables or figures), emphasizing their distributions.
Include simple bivariate analyses that explore the relationships between key variables (e.g., means by group, correlations, contingency tables).

Analysis Plan¶

For each research question, state the planned statistical approach.
Specify the null and alternative hypothesis for each test, with regard to your model parameters.

In Class¶

This week's class will be a workshop session to address any questions you may have about the project.

Reflection¶

How do you feel the consulting work is going so far? What has been the most difficult aspect of this work?
