NR449 Evidence-Based Practice Quiz 4 CORRECT RATIONALES 2024

All qualitative researchers must take the following actions: - CORRECT ANSWERS-- Prepare the data for analysis. - Conduct the analysis by developing an in-depth understanding of the data. - Represent the data in reduced form. - Interpret the larger meaning of the data ANOVA - CORRECT ANSWERS-- One of the most frequently used statistical tests in evidence-based research studies. - It is a staple for testing the effectiveness of interventions because of its versatility and its capacity to produce a tremendous amount of information. - It is effective in studies utilizing experimental and quasi- experimental designs Bivariate analysis - CORRECT ANSWERS-Analysis of two variables at a time, as in correlation studies - Ex. Determining if blood pressure is associated with sodium intake Codebook - CORRECT ANSWERS-A guide for the qualitative analysis that outlines individual codes with definitions, criteria for inclusion, and examples Codes - CORRECT ANSWERS-Labels, descriptions, or definitions assigned to data to allow them to be categorized and analyzed in qualitative research Coding process is used.. - CORRECT ANSWERS-both to generate descriptions and to begin interpretation of themes and patterns in the data Cohen's Kappa - CORRECT ANSWERS-A measure of inter-rater or inter-coder reliability between two raters or coders. The test yields the percentage of agreement and the probability of error - Generates p value for probability that random error was responsible for agreement Confidence interval - CORRECT ANSWERS-A range of values that includes, with a specified level of confidence, the actual population parameter - Used to estimate population parameters Constant comparison - CORRECT ANSWERS-A method of analysis in qualitative research that involves a review of data as they are gathered and comparison to data that have been interpreted to support or reject earlier conclusions Decision Trail - CORRECT ANSWERS-A detailed description of the researcher's decision rules for data categorization and inferences made in the analysis Dictionary - CORRECT ANSWERS-Specified definitions of codes included in the qualitative analysis codebook Editing Analysis - CORRECT ANSWERS-A style of analysis geared toward interpretation of text to find meaningful segments Effect size - CORRECT ANSWERS-The size of the differences between experimental and control groups compared to variability; an indication of the clinical importance of a finding - Determine how much of an effect can be expected Error Multiple Comparisons - CORRECT ANSWERS-The increased error associated with conducting multiple comparisons in the same analysis; the 5% allowable error for each test is multiplied by the number of comparisons, resulting in an inflated error rate Factors - CORRECT ANSWERS-Independent variables in an ANOVA that are measured as categories Four Basic Kinds of ANOVA - CORRECT ANSWERS-1. Univariate ANOVA - applied to determine if groups differ on a single numerical outcome 2. Repeated-measures ANOVA - used to determine if time is a factor in treatment conditions 3. Analysis of Covariance (ANCOVA) - used to determine if a covariate— commonly an extraneous variable—has an impact on the experiment 4. MANOVA - the multivariate version of ANOVA, is the most complex version of the test Goals of the Analysis - CORRECT ANSWERS-- Evaluate differences between groups (ex. control and experimental group) - Sort data - Aid in data reduction by grouping variables into overall classifications Guidelines for Conducting ALL Types of Quantitative Analysis - CORRECT ANSWERS-1. Select tests a priori 2. Run all the tests identified 3. Report all the tests that were run Help the novice researcher conduct a trustworthy analysis that results in meaningful themes: - CORRECT ANSWERS-- Establish the goal of the analysis - Organize the data - Begin analysis early - Read individual pieces of data in their entirety for tone - Reread each piece of data for meaning - Develop codes Immersion/crystallization Analysis - CORRECT ANSWERS-A style of analysis that uses total immersion in and reflection on the text, usually in personal case reports Inquiry Audit - CORRECT ANSWERS-A review of data and relevant documents, procedures, and results by an external reviewer Interferential analysis - CORRECT ANSWERS-Statistical tests to determine if results found in a sample are representative
