control variable D. constant variable 相关知识点: 试题来源: 解析 A。解析:在实验中,由科学家改变的变量被称为自变量。选项 B“dependent variable”是因变量,是随着自变量的变化而变化的变量。选项 C“control variable”是控制变量,保持不变以确保实验的准确性。选项 D“constant variable”是常量变量,也是保持不变...
解析 B。在实验中,由科学家改变的变量被称为自变量;“dependent variable”是因变量,是随着自变量的变化而变化的变量;“control variable”是控制变量,是为了确保实验结果准确而保持不变的变量;“experimental variable”不是一个标准的实验术语。所以选 B。

come) variable (through t tests and analyses of variance). Examples of whether two different variables are related to each other are plentiful throughout science and its many disciplines. We may wish to know whether cigarettes are related to cancer, whether violent crime rates are related to ...
Therefore, the aim of the tutor's investigation is to examine whether these independent variables - revision time and IQ - result in a change in the dependent variable, the students' test scores. However, it is also worth noting that whilst this is the main aim of the experiment, the ...
