$1.$ Let$$s pretend you will be presenting results from the Partnership for Girls Study at the American Public Health Association $($APHA$)$ Meeting this year. There are many interesting focal relationships you can investigate with these data, but there is only room for one analysis. Review the study survey $($posted on Camino$)$ to help you get familiarized with the type of data available.

What is a focal relationship you would be interested in exploring with these data? Discuss this as theoretical constructs$/$ideas$.$

What variable would you use as your independent variable? That is$,$ how would you operationalize the independent variable?

What variable would you use as you dependent variable? That is$,$ how would you operationalize the dependent variable?

$2.$ Open the Partnership for Girls data. For each of the following variables, answer each of the following questions: $($a$)$ What type of variable is it $$ e$.$g$.,$ continuous, discrete, dichotomous, nominal, or ordinal? $($b$)$ Describe the variable label.

GHT$11$

GQ$01$PA$1$

GQ$01$PAK$1$

Use the describe and tab commands to help you complete these questions.

describe variable$\_$name

tab variable$\_$name, m

$3.$ Provide information about each variable$$s numerical mapping. $($a$)$ For continuous and$/$or discrete variables, provide the range of responses. $($b$)$ For categorical variables, provide information on the value labels of each category.

For categorical variables, you will use the describe command again to determine the name of the value label. Once you find the value label name, run the label list command to get information on the actual value labels. Below is some sample code.

describe variable$\_$name

label list value$\_$label

For continuous variables, you will use the summarize command to view the range of response.

summarize variable$\_$name

$4.$ Choose a categorical variable from the list of variables you have been reviewing in Q$1-$ Q$3.$ Create a frequency table using the tab Take a screenshot of your results and include it in your document. What does the table suggest about this particular variable? Interpret the results in your own words.

$5.$ We sometimes have several variables$/$items in a dataset that are measuring a particular construct of interest. In these situations, it is best to combine these variables and create a composite score of the variables$/$items $($e$.$g$.,$ total score$).$ Carefully review the variables in the Partnership for Girls Data. Feel free to review the study survey. Provide one example of any variables that look like they should be combined into a single composite variable. List the variable names and their labels. Briefly explain what you think these items are collectively measuring.

$6.$ We are interested in creating a variable that measures the extent the girls in our sample receive support to participate in physical activity. Key variables of interest, include: GQ$01$SS$1$ GQ$02$SS$1$ GQ$03$SS$1.$

Collectively, what are these variables attempting to measure?

Describe the numerical mapping of these variables.

Let$$s create a new variable called friend$\_$support using the three items above. Use the code below. Estimate a frequency table of the new variable $($hint: you will use the tab command$).$ What does it look like now? What type of variable did you just create $($e$.$g$.,$ categorical, continuous, discrete, etc.$)?$

egen friend$\_$support $=$ rowmean$($GQ$01$SS$1$ GQ$02$SS$1$ GQ$03$SS$1)$

What does a higher score on the friend$\_$support variable mean?

After creating the new calculated variable, what kind of label might you give it to describe what it is$?$ Be as crafty$/$creative as you$$d like! Now label the variable using the following code and estimate another frequency table using the tab command. Include another screenshot of your result. What changed now?

label variable friend$\_$support $$insert your label$$

$7.$ Congratulations! You now have some experience using Stata! Are there any things that you found helpful while doing this lab? What are things that you would like to see in the future to better support you as you work on these lab assignments in class?
