1. In a study that DMV is conducting, applicants renewing their driver licenses are assigned to one of three groups based on their actual best-corrected performance scores on the Snellen static-visual acuity chart (that chart with the letters you have to read to the technician). The three groups are: (a) applicants with 20/40 or better visual acuity, (b) applicants with visual acuity between 20/50 and 20/100, and (c) applicants with visual acuity worse than 20/100. The accident rates of the groups 2-years subsequent to license renewal are compared. The research is being conducted to support a minimum visual acuity standard for driving in California by demonstrating that poorer visual acuity is associated with higher accident rates. The dependent variable(s) in this study is/are:

4. In another study that DMV is conducting on home-study driver education, driver license applicants under the age of 18 will be randomly assigned to receive one of four types of driver education instruction: (a) a 30-hour classroom course, (b) an interactive computer CD ROM course, (c) a paper-based home-study kit based on a standardized curriculum, or (d) a paper-based home-study kit based on a non-standardized curriculum. DMV written test errors and DMV drive test errors will be collected after the customers complete training to compare the relative effectiveness of the different types of driver education instruction on driving knowledge and driving performance. The independent variable(s) in this study is/are:
