Statistics for Health Care Professionals notes

HLT-362V Week 3 DQ 1 - Explain when a z-test would be appropriate………. Applied Statistics for Health Care Professionals - Hypothesis Testing Grand Canyon University Explain when a z-test would be appropriate over a t-test. Answer 1 Z-test = Statistical test used to determine whether two population means are different when the variances are known and the sample is large. T-test compares the actual difference between two means in relation to the variation in the data Z-test is a stat...

HLT-362V Week 3 DQ 2 - Researchers routinely choose an alpha………… Applied Statistics for Health Care Professionals - Hypothesis Testing Grand Canyon University Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some situations in which you might accept a higher level (e.g., 0.1)? Answer 1 The significance level (alpha) is the probability of committing a type ...

Using the research article selected for DQ 1, identify three key questions you will ask and answer when reading the research study and why these questions are important. When responding to peers, provide other questions and answers that could be considered in relation to the peers' studies.

Select a research article, other than the articles from your assignments, from the GCU library. Provide an overview of the study and describe the strategy that was used to select the sample from the population. Evaluate the effectiveness of the sampling method selected. Provide support for your answer. Include the article title and permalink in your post There is a major problem in clinical research. The researcher tries to solve and control the outcomes. Several approaches can be consulted...
