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 dependent variable.”,即在实验中,研究者...
In theBandura Bobo Doll experiment, whether the children were exposed to an aggressive adult, or to a passive adult, was the independent variable. This experiment is a prime example of how the concept of experimental variables can become a little complex. Bandura also studied the differences betw...
Since this other factor changes in response to the independent variable, that factor is considered to be the dependent variable. What is the independent variable in an experiment? The independent variable is the variable that is manipulated or changed by the scientists in a controlled experiment. ...
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...

Therefore, the variable of daylight in this scenario would be considered the dependent variable because it depends on what time of year it is. If one were to run an experiment to determine which type of fertilizer produces the highest number of strawberries from a single strawberry bush, they ...
Students are often asked to identify the independent and dependent variable in an experiment. The difficulty is that the value of both of these variables can change. It is even possible for the dependent variable to remain unchanged in response to controlling the independent variable. Example: You...
In a scientific experiment, the independent variable is manipulated to observe its effect on the dependent variable.Which of the following is an example of an independent variable? A. The temperature of a reaction. B. The color of a solution. C. The time it takes for a reaction to occur....
In an experiment to determine how far people can see into the infrared part of the spectrum, the wavelength of light is the independent variable and whether the light is observed (the response) is the dependent variable. If you want to know whether caffeine affects your appetite, the presence...
