What is an independent variable in math?Variables in Mathematics:In mathematics, variables are symbols, usually letters, used to represent a quantity or value within a problem. We can create equations using variables in mathematics, and an equation has different types of variables within it. These...
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 dependent variable.”,即在实验中,研究者操纵自变量并观察其对因变量的影响,所以自变量是被操纵的变量。
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 B。选项 A,被测量的是因变量,不是自变量。选项 C,自变量不是常量值。选项 D,自变量不是研究方法。反馈...

On any graph with x and y axes there is a dependant variable and an independent variable. The independent variable is placed on the y-axis. The independent variable is often the one that either we directly control such as length of time....
对随机误差来说，无限次测量一般做不到，只能做有限次测量，故可确定的只是随机误差的估计值。旋进旋涡流量计旋涡发生体用铝合金制成，具有一定角度的螺旋叶片，它固定在壳体收缩段前部，强迫流体产生强烈的漩涡流。( )
A. The variable that is changed by the experimenter. B. The variable that changes in response to the independent variable. C. The variable that is kept the same. D. The variable that is not important. 相关知识点: 试题来源: 解析 A。在实验中,自变量是由实验者改变的变量。选项 B 是因变量...
