Calculate an odds ratio A group of teens ages 13-17 with anxiety were chosen as cases in a case-control study. A second group of teens ages 13-17 without anxiety were chosen as controls for the same study. The researchers were investigating if attention deficient and hyperactivity disorder (ADHD) is a potential risk factor (exposure) for anxiety (outcome). The medical histories of cases and controls were examined to determine if participants had been diagnosed with ADHD between ages 8 and 10. Among cases (teens with anxiety), 77 had been diagnosed with ADHD between ages 8 and 10 and 34 had not been diagnosed with ADHD between ages 8 and 10. Among controls (teens without anxiety), 18 had been diagnosed with ADHD between ages 8 and 10 and 124 had not been diagnosed with ADHD between ages 8 and 10. Calculate the odds ratio to measure the association between being ADHD and anxiety in teens. Express your answer to the nearest tenth or 1 place past the decimal (example: 15.4).

Calculate an odds ratio
A group of teens ages 13-17 with anxiety were chosen as cases in a case-control study. A second group of teens ages 13-17 without anxiety were chosen as
controls for the same study. The researchers were investigating if attention deficient and hyperactivity disorder (ADHD) is a potential risk factor (exposure) for
anxiety (outcome). The medical histories of cases and controls were examined to determine if participants had been diagnosed with ADHD between ages 8
and 10.
Among cases (teens with anxiety), 77 had been diagnosed with ADHD between ages 8 and 10 and 34 had not been diagnosed with ADHD between ages 8
and 10. Among controls (teens without anxiety), 18 had been diagnosed with ADHD between ages 8 and 10 and 124 had not been diagnosed with ADHD
between ages 8 and 10.
Calculate the odds ratio to measure the association between being ADHD and anxiety in teens. Express your answer to the nearest tenth or 1 place past the
decimal (example: 15.4).
