Learning Goal: I’m working on a public health question and need an explanation to help me learn.Part 1: Survey DesignQUESTION 1a: The Monitoring the Future Survey uses a cross sectional study design (as opposed to a longitudinal study design). What does this mean?Answer: The monitoring the future survey uses a cross sectional study design which means that data is collected at one point in time on a statistical unit. QUESTION 1b: You are working at San Diego Health and Human Services as a community health educator. You would like to begin a new project that will involve developing health education programs for teenagers to prevent substance use. But your boss is unsure if such a program is needed and asks you to provide information on if substance use has been increasing, decreasing, or staying the same among teenagers in San Diego over the last few years. Can you answer this public health question using our dataset (the 2019 Monitoring the Future Survey, 12th grade)? Why or why not?Answer: looking at the data base, it looks like substance use has been decreasing among teenageas nationally, however looking at San Diego teenagers it is hard to tell from the data since it doesn’t give us exact data for each county therefore, it will be hard to determine if substance use is increasing, decreasing or staying the same among teenagers in San Diego but it is always a good initiative to start and develop health education programs for teenagers to spread awareness and further educate them. QUESTION 2: Based on your output, what are the levels of measurement for each of these variables? Are any of these levels of measurement incorrect? If so, which ones? Why?Answer: Based on our output, the levels for each variables are as follows, for sex is nominal, for race and ethnicity is nominal and for vaping marijuana in the last 30 days is nominal. The level of measurement for Vaping is incorrect because it is ranked in a hierarchical fashion in a non-numerical clear way therefore it should be ordinal. QUESTION 4: How many of the participants are Black, white, Hispanic/Latinx? How much missing data is there on race/ethnicity? Answer: 1262 of the participants were black or 9.2%, 6970 were white and made up 50.8% of the participants, 2538 were hispanic/latinx and made up 18.5% of the participants. 2943 or 21.5% was missing data on race/ethnicity. QUESTION 5: How many of the participants are male, female? How much missing data is there on sex? Answer: 6123 of participants are males and make up 44.7%, 6540 of participants are female and make up 47.7% of the participants. 1050 or 7.7% is missing data on sex. QUESTION 6: What proportion of participants did not vape marijuana at all in the last 30 days? What proportion of data is missing on this variable?Answer: the proportion of participants that did not vape marijuana at all in the last 30 days is 7048/13,713 which is 51.4% of all participants. The proportion of data is missing on this variable is 5399/13,713 which is 39.4%.
