Directions: Answer the following questions by reviewing the statistical content and applying the algorithm in Figure 12-1 of this exercise (Grove & Cipher, 2020).
1: Discuss the differences between parametric and nonparametric statistical techniques. Provide an example of a parametric statistical technique and a nonparametric statistical technique applying the algorithm in Figure 12-1.
Answer: –
2: What statistical technique was probably conducted for a study focused on examining associations or relationships that had variables measured at the ordinal level and included one group? Provide a rationale for your answer.
Answer: –
3: What statistical technique was probably conducted for a study focused on examining differences that had variables measured at the ratio level and included three independent groups (intervention, placebo, and control)? Provide a rationale for your answer.
Answer: –
4: What statistical technique was probably conducted for a study focused on predicting a dependent variable using one independent variable that was measured at the interval/ratio level in a sample of patients with heart failure? Provide a rationale for your answer.
Answer: –
5: What statistical technique was probably conducted for a study focused on examining differences that had variables measured at the ordinal level and included three paired samples or groups? Provide a rationale for your answer.
Answer: –
6: Study hypothesis: Nurses working in healthcare organizations with magnet status have higher job satisfaction than nurses working in organizations without magnet status. Job satisfaction was measured with a multi-item Likert scale. What statistical technique would researchers probably conduct to test this hypothesis? Provide a rationale for your answer.
