In the process of mathematical modeling, the factor that determines the outcome is called___. A. independent variable B. dependent variable C. control variable D. extraneous variable 相关知识点: 试题来源: 解析 B。本题考查数学建模中的基本术语。独立变量(independent variable)是指在实验或研究中被...
Another complex example is: if in a study, the outcome of a test is measured by test scores, the dependent variable would be the final result of each participant in it. In research, the dependent variable is considered the stable part of the analysis. On the other hand, the independent...
Mediation analysis allows an understanding of if and to what extent a variable M mediates the effect of a treatment variable A on the outcome variable Y. Hence, the mediator is supposed to uncover the channels through which the exposure variable affects the outcome variable (MacKinnon, 2008). ...
Furthermore, the outcome of environmental regulation exhibits greater efficacy in urban areas compared to rural areas. Lastly, market-incentive environmental regulation in reducing health costs is more effective than command-controlled regulation. Conclusions Enhancing the intensity of environmental regulation ...
Dichotomous Outcome Variables Some research questions involve dichotomous dependent (outcome) variables. If so, we use proportions or percentages as descriptive statistics for summarizing such variables. For instance, people may or may consider buying a new car in 2017. We might want to know theperce...
Dependent variable refers to the variable being tested and measured in an experiment or study, which is expected to change as a result of changes in the independent variable.
A dependent variable is also known as an outcome variable. Techopedia Explains Dependent Variable A dependent variable is primarily a value that is being accessed, evaluated or calculated within/through a computer program or process. The value of the dependent value entirely depends on independent va...
In general, if you are studying the effect of a certain factor or the outcome of an experiment, the effect or outcome is the dependent variable. If you measure the effect of temperature on flower color, temperature is the independent variable—the one you manipulate—while the color of the ...
A two-way analysis of variance (ANOVA) is a statistical test used to determine the effect of two nominal predictor variables (two independent variables) on a single, continuous outcome variable (dependent variable). A two-way ANOVA analyzes the main effect of each of the independent variables o...
Used to not only understand the individual effects of two different factors but also how the combination of these two factors influences the outcome Can test for interactions between factors A one-way ANOVA evaluates the impact of a single factor on a sole response variable. It determines whether...
