control variable D. experimental variable 相关知识点: 试题来源: 解析 B。因变量(dependent variable)是在实验中被测量以观察结果的变量,它取决于独立变量的变化。选项 A“independent variable”是主动改变的变量;选项 C“control variable”是控制变量;选项 D“experimental variable”不是科学实验中常用的特定术语...
A. independent variable B. dependent variable C. control variable D. constant variable 相关知识点: 试题来源: 解析 B。在实验中被测量的变量称为因变量。选项 A 是自变量,是实验者主动改变的变量。选项 C 是控制变量,保持不变。选项 D 是常量变量,同样保持不变。反馈...
The variable that is observed and measured to see how it changes in response to the independent variable is _. A. independent variable B. controlled variable C. dependent variable D. fixed variable 相关知识点: 试题来源: 解析 C。本题考查因变量的概念。因变量(dependent variable)是被观察和测量...
The variation in the dependent variable explained by the independent variable is measured by the:Amean squared error. Bsum of squared errors. Cregression sum of squares. 相关知识点: 试题来源: 解析 C The regression sum of squares measures the variation in the dependent variable explained by ...
aThe dependent variable used in this study has been measured in two ways. First, and similarly to Ozkan and Ozkan, we used the variable CASH1, calculated as the ratio of cash and marketable securities to total assets. Second, we used the variable CASH2, which is identical to CASH1 except...
usually measured along the x-axis and the dependent variable along the y-axis. For example, if you were examining the effect of sleep on test scores, the number of hours participants slept would be plotted along the x-axis, while the test scores they earned would be plotted along the y-...

"The Mean Effect of Structural Change on the Dependent Variable is Accurately Measured by the Intercept Change Alone", Economics Letters, 80, 255-259.Higgins, Richard S. and Paul A. Johnson (2003), "The mean effect of structural change on the dependent variable is accurately measured by the...
Independent variable:What the scientist changes or what changes on its own. Dependent variable:What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment. Either the scient...
The independent variableis the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the ex...
