INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

This assignment builds on Data Analysis 1 and uses the same data set from a survey administered to 261 young adults. As a reminder, the goal of this cross-sectional survey was to characterize substance use and correlates of substance use in the population of young adults. 

 Subsequent to the descriptive analyses from Data Analysis 1, your task in this portion of the assignment is to perform bivariable analyses.

 Use the variable TOTALDRUGS and one of the other two composite drug use variables (ILLEGALDRUGS1 or ILLEGALDRUGS2). Then, for each of these two and all of the demographic and mental health factors, pick and perform the correct bivariable association test.

 Report results, including non-significant findings for each test.

 Also in this assignment, put your results into words, using the research papers we’ve been reading as examples. You will also incorporate your results from Data Analysis 1 assignment. The sections you should create are:

 1)   Sample/Data Characteristics (2 points)

a)    Summary of the demographic variables (you may use summary()or table()commands in R, but points for this question is mainly from the well described paragraph(s)) (2/3 point)

b)    Drug use and mental health variables: descriptive statistics (4/3 points).

Along with well-written paragraphs, provide two separate summary tables for drug use and mental health variables (Hint: don’t calculate mean for categorical variables. Use past RR readings as your references). 

2)   Analytic Plan (describe analyses chosen) (2/3 point)

a)    Describe what bivariate tests were chosen and why

3)   Bivariable analyses (from this assignment) (4/3 points)

a)    Interpret your findings in well-described paragraph(s)

b)    You may include up to 2 plots

4)   Include all of your R code (2/3 point)

5)   Overall formatting (1/3 point)
