Q1- How many pairwise comparisons are necessary if a researcher wishes to compare a quantitative variable across a factor with 7 levels? What is the probability of making at least one Type I Error when comparing a quantitative variable across a factor with 7 levels if each pairwise comparison is conducted using a 10% significance level?

Q2- Provide an example setting where a One-Way Analysis of Variance (ANOVA) would be an appropriate statistical technique for analysis? Include the following:

• Research Question or Claim to be Tested

• Description of variables i.e. Categorical (also indicating nominal, binary/dichotomous, or ordinal and providing levels) or Quantitative (also indicating discrete or continuous)

o Dependent Variable:

o Independent Variable:

• Null and Alternative Hypotheses (using proper notation)

    4. Assume a researcher wishes to compare student mathematics performance on a standardized test among three 6th grade teachers: Ms. White, Ms. Jones, and Ms. Griffin. The researcher will use ANOVA to first determine if there are differences in mean mathematics scores among the three teachers, and if there are significant differences, then the researcher will perform multiple comparisons to examine the following pairwise comparisons: Pairwise comparisons of Mean Mathematics Scores i. Ms. White vs. Ms. Jones ii. Ms. White...

    Procalcitonin (PCT) is used as a biomarker for the diagnosis of sepsis and is also used to guide antibiotic therapy. PCT levels (ng/mL) parallel the severity of bacterial infection. Consequently, low PCT levels indicate no bacterial infection while high PCT levels indicate mild to severe bacterial infection. A researcher was interested in studying the relationship patient sex (Female vs. Male) and/or physician diagnosis for the patient (TSS Diagnosed vs. TSS Not Diagnosed) has with average PCT levels. With this additional...
