Correlation and Regression in Statistical Research Report (Assessment)

Introduction Correlations, linear regressions, and multiple regressions are the three most common methods used to investigate a relationship between several quantitative variables in research. These methods are utilized in many areas of quantitative scientific research, such as economics, medicine, psychology, sociology, etc. Correlations and regressions are different from one another. Correlation is used to quantify the strength of a relationship between two variables. Regression, on the other hand, reverses this relationship and expresses it in the form of an equation, which allows predicting the value of one or several variables based on the known values of the remaining ones. The choice between using correlation or regression largely depends on the design of the study and the research questions behind it. The purpose of this paper is to evaluate correlations, linear regressions, and multivariate regressions, identify the essential assumptions behind them, assess their essential components, and underline their weaknesses and limitations. Correlational Research The word “correlation” stands for the association between two or more variables (Cramer, 2016). The purpose of a correlational statistical model is to express and explore the strength of this association and identify the relationship between different variables. The relationship, or co-variation, is typically expressed as a positive or negative (Cramer, 2016). Alternatively, when there is no association between the variables, it is indicated by the pattern of the results. The relationship between the variables is presented through correlational coefficients, ranging from -1 to 1 (Cramer, 2016). Since correlations are linear, these coefficients indicate the measure of the distance of the individual results from the straight line. The most popular method of testing a correlation is the Pearson method. Strengths of Correlational Method A correlational research design is typically implemented in situations when the object of the study is to study the relationship between two or more variables without isolating them (Cohen, Cohen, West,

NOTE TO TUTOR: This is an easy HW, you just need to highlight the 12 parts of the article listed below. Step 1: Download PDF of the articleBorgh, Chris van der, and Wim Savenije. 2019. “The Politics of Violence Reduction: Making and Unmaking the Salvadorean Gang Truce.” Journal of Latin American Studies 51 (4): 905–28. https://doi.org/10.1017/S0022216X19000890. STEP 2: ANALYZE THE ARTICLEIdentify the 12 parts of the article belowTypical Anatomy of a Journal Article in Political ScienceJournal Articles, especially in the field of political science, typically have twelve parts.The Title of an article appears on the first page of the article. The Title is brief, typically no more than 5-10 words, and identifies for the reader the subject of the article.The Main Point of an article is typically found in the Abstract. An Abstract is a summary of the article which is located on the first page, after the Title. The main point may be in the Introduction of the article.The Question of an article is typically found in the Abstract. The question may be in the Introduction of the article as well.The Puzzle is a missing piece of knowledge that the article seeks to fulfill.The Debate is how scholars currently argue the subject of the article. Debates have at least two sides, and the two sides we are most familiar with are “pro” and “con”. However, debates can be more complex.The Theory is how the author thinks something works. For example, we may have a theory about how campaigns influence voters. Theories consists of constants, variables, and the relationships between variables.The Hypotheses are derived from the Theory. A hypothesis is the expectation that one variable affects another variable in a specific way.The Research Design is how the author compares the effect of the explanatory variable (X) on the outcome variable (O) in a group (G) or set of groups.The Empirical Analysis is the use of quantitative or qualitative evidence to explore whether the hypothesized relationship between two variables does indeed occur in the world.The Policy Implications are how the findings of the article should influence the behavior of individuals, groups, organizations, or governments.The Contribution to the Discipline is how the article helps fill the missing Puzzle pieceFuture Research offers suggestions for future research that build on the findings from the article.
