Questions Discussion Board: Instructions
Purpose: The purpose of this assignment is to familiarize you the complexity of quantitative statistical analysis.
Instructions: For this discussion, please complete the following:
1. Review the assigned chapters in Polit and Beck (2017): i.e., chapters 18-20.
2. Identify five different facts or pieces of information that pertain to the topic.
3. Construct 3 multiple choice questions based on the information in the text and post these questions to the discussion board no later than Wednesday by 11:59 pm.

Comprehensive General Response:
Five Key Facts from Polit & Beck (2017), Chapters 18–20:
-
Descriptive Statistics: These summarize and describe the main features of a data set, including measures such as mean, median, and standard deviation.
-
Inferential Statistics: These allow researchers to make generalizations from a sample to a population, using tools like confidence intervals and hypothesis testing.
-
P-Value Significance: A p-value less than 0.05 is commonly used to indicate statistical significance in hypothesis testing.
-
T-Test vs. ANOVA: A t-test compares means between two groups, while ANOVA (Analysis of Variance) compares means among three or more groups.
-
Correlation Coefficient (r): This measures the strength and direction of a linear relationship between two variables, ranging from -1 to +1.
