Why An Independent Variable Affects A Dependent Variable Essay

explores the interaction of variables within a quantitative research. A variable in research can be an individual or group, which is observed for various measurements during an experiment (Creswell, 2014). Additionally, variables used within an experiment is used to observe the reactions of how each variable interacts with each other and the dependent variable. The effects of each variable help determine the outcome of a study or experiment. In order to understand the variables, they must first be identified…
Authors/citation Study purpose/ Research question Sample/ Participants Design Variables: Dependent Independent Procedures Analysis Results Recommendations Level of Evidence Mukhopadhyay et al., 2010 This study has two purposes: The first purpose is to see whether a restrictive blood transfusion along with blood conservation system will decrease the amount of pack red blood cell transfusion. The second purpose is to see whether the blood conserving apparatus will conserve hemoglobin level from admission…
inability to accurately represent reality, there are no overtly obvious issues regarding the measurement or operationalization of this variable. The central independent variable I chose was number of group memberships. The variable was measured by simply asking respondents for the number of groups that they belonged to. The unit of analysis in individuals, and the variable is continuous. The mean is 0.833, indicating that the number of memberships is skewed toward zero, with the mean not quite reaching…
The results of this experiment were taken from the tracked variables. The independent variables were amount of sleep attained, and the time of day which participants were given the encoding phase of the experiment. Dependent variables in regards to memory were taken from the first experiment. Those were correct-memory scores, the misinformation-consistent responses, and the false memory rates. New dependent variables were sleepiness, affect, and working memory capacity. These results were tracked using…
To empirically test the first hypothesis, forecast accuracy is the dependent variable measured by the absolute difference between the analyst EPS forecast and actual EPS scaled by the analyst EPS forecast. The regression is based upon the model formed by Behn et al (2007) with some additional or omitted variables. The following model is used to test H1: Afore_bias2 = c1 + c2 auditor + c3 mv + c4 eps_std + c5 vol_252 + c6 horizon_to_FYR + c7 ind_exp + c8 analyst_no_firm_followed In accordance with…
Operational Definition of Variables Operationalization of compliance and sales variables/method of collection of data/measurement of the data Operationalization of the variables refers to the process of quantifying how the variables will be measured and explaining what exactly a given variable means. For example, one variable that will be measured is that of compliance with regard to the percentage of usage of the technology during the study period. Compliance will be considered measurable if…
sum of objective terms by selecting optimal feasible levels of the independent variables. The set of process limits or constraints define the feasible region. For example, upper and lower limits on the independent variables are constraints on the problems. Additionally, there are dependent variables that aid in defining the objective terms and/or constraints. These dependent variables are functions of the independent variables. A glossary of terms can be found in Appendix A. This invention consists…
research methods, the focus of the research is to collect data that can test both dependent and independent variables (Cresswell, 2008). The nature of the dependent variable (social media) in the hypothesis dictates the methodology and design for this perspective study. Therefore, the researcher is proposing an exploratory research to fully expose the potential and conceptual distinctions of the dependent variable as a static field resource for law enforcement efforts. The results of the exploratory…
specified on variables. Take x and y to be two variables. A function f may map x to some expression in x. Assigning gives a relation between y and x. If there is some relation specifying y in terms of x, then y is known as a dependent variable (and x is an independent variable). Statistics In a statistics experiment, the dependent variable is the event studied and expected to change whenever the independent variable is altered.[1] Modelling In mathematical modelling, the dependent variable is studied…
This model has 7 variables and 11 hypotheses which are: • Variable One is Crime The variable measures Intentional homicides (per 100,000 people). Intentional homicides are assessments of illegal homicides intentionally caused due to domestic disputes, interpersonal violence, and violent conflicts over land resources, inter-gang violence over turf or control, and predatory violence and killing by armed groups. Intentional homicide does not include all intentional killing; the difference is usually…
