Question

1. Identifying basic components of an ANOVA Aa Aa The U.S. Department of Health and Human Services compiles statistics on the consumption of alcohol. An investigator decides to look at the role of age in determining alcohol use. She requests data on the amount of drinking done by three different age groups: 16- to 20-year-olds, 21- to 25-year-olds, and 2 26-year-olds. The results come in, and a statistician conducts an analysis of variance. The is that at least one of the age groups has an effect on the amount of alcohol -consumed 2 The is that the age groups have no effect on the amount of alcohol consumed Note: The term treatment effect is used even when there is not actually a treatment 3 The age group is The treatments (16-to 20-year-olds, 21- to 25-year-olds, and 2 26-year-olds) are The amount of alcohol consumed is Which of the following might contribute to variation in responses between factor levels? Check all that apply Individual differences in the frequency of drinking Flaws in the questionnaire used to measure the amount of drinking Systematic differences in drinking frequency by age group Answer the above BLANKS from these answers: 1. 2. 3. 4. 5. 6. Null Hypothesis or Alternative Hypothesis? Alternative Hypothesis or Null Hypothesis? The different levels of the factor or the response variables or the factor The different levels of the factor or the response variables or the factor The different levels of the factor or the response variables or the factor Check all that apply
