As a reminder, inferential statistics are used to determine the probability that a conclusion based on analysis of data from a sample is true (Norman & Streiner, 2008). The purpose of this discussion is to show the various types of hypotheses, how to identify them in an article and the importance of “significance” and a p-value.
For this discussion, use a peer-reviewed article (focused on a health study) of your choice to:
• Identify the Ho and H1
• Identify and explain what “significance” is in a general sense and in your chosen article. Be sure to discuss the p-value.
Week 4

• Identify the types of variables you would need to conduct:
o a Chi-square (for students whose last name begins with A-H)
o one-sample t-test (for students whose last name begins with I-P)
o paired t-test (for students whose last name begins with Q-Z)
• Be sure to explain the number of dependent and independent variables, and the types of dependent variables necessary for the statistical analysis.
• Provide a health-related example (or use a peer-reviewed article that used the statistical analysis) to explain your answer.
