Which statistic was probably conducted for a study focused on examining differences that had variables measured at the ordinal level and included two independent samples or groups? Provide a rationale for your answer. 2. Which statistic was probably conducted for a study focused on examining relationships that had variables measured at the ratio level? Provide a rationale for your answer. 3. Which statistic was probably conducted for a study focused on examining differences that had variables measured at the nominal level and included one group? Provide a rationale for your answer. 4. A study was focused on examining differences among the randomly assigned intervention, placebo, and standard care groups and the dependent variable perception of pain was measured at the interval level with a Likert pain scale. However, the data on pain perception were skewed (not normally distributed). What statistic was probably conducted to analyze the pain perception data? Provide a rationale for your answer. 5. Study Hypothesis: Women taking calcium 1,200 mg plus Vitamin D3 2,000 International Units (INU) have higher bone density scores than women taking only calcium 1,200 mg. The women were randomly selected and assigned to the intervention and standard care groups. Which statistical technique would researchers probably conduct to test this hypothesis? Provide a rational for your answer.
