Problem statement: Kuya conducted a study to investigate whether age and education level can be good predictors for one’s capacity to direct attention (CDA) among elderly subjects. Data were collected on all three variables. Are age and educational level good predictors for CDA?
Answer: In this problem Since you have three vaiabes , also you can't predicats good for CDA for using age and educational level, so in this problem you may used repeated measurements ANOVA or correlation analysis to check the variations and effects of three vaiables.
Problem statement: Kuya conducted a study to investigate the relationship between smoking habits and weight. Subjects were distributed into categories of smokers and nonsmokers. Weight were categorized into underweight, appropriate weight, and overweight. Is there a relationship?
