I'm researching the NLSY79 and NLSY97 cohorts and need to compare data. Explain why creating comparable samples is important and outline the five main steps for constructing a parallel sample, using 'work status at age 20' as an example, as detailed in the website's tutorials.
Navigate to the 'How to access and create NLS data sets' section. Locate and click on the 'Tutorials and Videos' link. Find and access the tutorial titled 'Constructing Comparable Samples across the NLSY79 and NLSY97'. Read the tutorial to identify the reason for needing comparable samples. Identify and list the five key steps for constructing a parallel sample, specifically referencing the 'work status at age 20' example. Summarize the reason for comparability and list the five steps.
State that constructing comparable samples is necessary due to 'small differences in design' between the NLSY79 and NLSY97 cohorts. List all five key steps for constructing comparable samples as described in the tutorial: 'Select the samples for analysis', 'Determine the age and the interview years you will need', 'Create a tagset of variables to define work status at age 20 for NLSY79', 'Create a tagset of variables to define work status at age 20 for NLSY97', and 'Construct work status variable for both samples'.
