What is a dependent variable? The dependent variable is the variable measured in an experiment. It depends on the independent variable! What is a control variable? Control variables are variables that must be kept the same in an experiment. ...
A. The variable that is measured. B. The variable that is manipulated. C. The variable that is controlled. D. The variable that is observed. 相关知识点: 试题来源: 解析 B。原因:文章中提到“In an experiment, researchers manipulate an independent variable and observe the effect on a depende...
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 ...
When independent and dependent variables are plotted on a graph, the independent variable is 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 pl...
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...

A. The variable that is being measured. B. The variable that is manipulated by the researcher. C. A constant value. D. A research method. 相关知识点: 试题来源: 解析 A。选项 B,被研究者操纵的是自变量,不是因变量。选项 C,因变量不是常量值。选项 D,因变量不是研究方法。反馈...
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...
We should consider that it is not always possible to distinguish quickly between a dependent and an independent variable. To determine which is the one among the variables, it is interesting to know that the dependent variable will always be the one that can be measured. Therefore, when the ...
Which type of variable is measured in both the experimental and control groups of an experiment? a. dependent b. independent c. extraneous d. correlated Find the independent variable, dependent variable, independent variable scale, and dependent variable for the fo...
