控制各种自变量与因变量
" is possible. This shows us that the independent variable affects the dependent variable. The inverse, however, is not true. "Plant growth causes a change in light color," is not possible. This way you know which is the independent variable and which is the dependent variable!
a Five operational variables were utilized for the study comprising one dependent variable, three independent variables.and one control variable as described in Table 1. 五操作的可变物为包括一个因变量,三独立variables.and一控制变量的研究在表1被运用了如所描述。[translate]...

fertilizer applied to the bean plants is what is measured and is the dependent variable in each experiment. The control group does not receive the variable. In the antifreeze experiment, the control part of the experiment would be at what temperature water actually starts to freeze with no antif...
Extraneous variables: These are variables that might affect the relationships between the independent variable and the dependent variable; experimenters usually try to identify and control for these variables. Confounding variables: When an extraneous variable cannot be controlled for in an experiment, it...
aControl variables-are a special type independent variables that researchers measure because they potentially influence the dependent variable. p.51(The water pressure) 控制可变物是研究员测量的一个特殊类型独立变量,因为他们潜在地影响因变量。 p.51(水压)[translate]...
a. Develop a hypothesis related to the human body. b. Describe the independent variable. c. Describe the dependent variable. d. Describe the control variable (group). What is systematic observations in biology? Explain how genotypes and phenotypes of the parents and offspring...
other variable in the experiment. Sometimes you may hear this variable called the "controlled variable" because it is the one that is changed. Do not confuse it with acontrol variable, which is a variable that is purposely held constant so that it can't affect the outcome of the experiment...
