- Which of the independent variables retains the strongest association with the number of children a respondent has when all other variables in the model are controlled? What is that association? Which has the weakest when other variables are controlled?Expression levels of GeneA and GeneB were measured in 10 cell lines. The researcher would like to know if expression levels of GeneA and GeneB are related.a. Use a parametric method to test if GeneA and GeneB are correlated.b. Use a non-parametric method to test if GeneA and GeneB are correlated.Which of the independent variables retains the strongest association with the number of children a respondent has when all other variables in the model are controlled?
- When looking at the matrix for a two-way ANOVA, which means (row, column, or cell means) do we look at to assess if there is an interaction effect? just row means just column means cell means row and column meansA researcher would like to evaluate the claim that drinking large quantities of water can help prevent the common cold. One group of participants drinks 8 glasses of water every day, and a second group drinks 2 glasses of water every day. The researcher records the number of colds each individual experiences during the 4-month winter season. what is the independent variable? what research method is being used experimental or correlational?A 2012 suvey conducted by Idea Works provided data showing the percentage of seats avail- able when customers try to redeem points or miles for free travel. For each airline listed, the column labeled 2011 Percentage shows the percentage of seats available in 2011 and the column labeled 2012 shows the correponding percentage in 2012 (The Wall street Journal, May 17, 2012). Develop a scatter diagram with 2011 Percentage as the independent variable. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? Develop the estimated regression equation. Test for a significant relationship. Use α = 0.05. Did the estimated regression equation provide a good fit?
