Applied ResearchExperimental and descriptive research designs, statistics and inferences in psychological contexts and methods differ in many ways but have similar qualities. All psychological research follows ethical codes and regulations. Each type of experience discussed contains similarities and differences. The importance of each research method to individuals and societies varies depending on the need addressed during project creation. Beneficial interventions and treatments are developed from the cause and effect of numerous research projects. Validity concerns become an essential part of every research project. Using descriptive and inferential statistics to maintain accuracy checks typically involves the use of analysis of variance (ANOVA) in comparison of research studies according to Shaughnessy, Zechmeister, and Zechmeister (2009). ANOVA specifies whether the independent variable showed an effect on the dependent variable through inferential statistical tests. Data and information from qualitative and quantitative psychological research can be analyzed and measured using ANOVA. A discussion of descriptive and inferential statistics, single-case study design, small-N study design, real-world experiment design, and quasi-experimental design follows in this article. Descriptive and Inferential Statistics Research data is described in both a descriptive and statistical format when used for accuracy inferences in research projects. Descriptive statistics provide a graphical or numerical portrait of the research data to be analyzed. Inferential statistics provide an indication of the general judgment or perception of the result inferred from the comparison of research. Inferential statistical methods use both medium of paper and design for research and in some cases they have advantages over other methods. It all depends on the research project.ConclusionIn conclusion, all research methods and data analysis are extremely important steps to ensure the quality of research results. Treatments and interventions resulting from research could not have validity and reliability without all experimental methods. The research preparation and data analysis stages play just as important a role as the research itself. Similarities and differences appear between all research design methods. Research ethics provides valid and reliable results for individuals and societies. ReferencesShaughnessy, JJ, Zechmeister, EB and Zechmeister, JS (2009). Research Methods in Psychology (8th ed.)
