Experiments must be carefully planned and designed, so the experiment on completion fulfills the objectives of the researcher. Although experiments are more difficult to conduct in the educational environment t
In stark contrast, dependent variables, also known as "responding variables," are the outcomes or responses measured as a result of changes in the independent variable. They are the "then" in the scientific hypothesis. In our plant growth experiment, the height of the ...
What are the dependent and independent variables in an experiment titled: The Association Between Parental Neglect and Childhood Obesity Rates in a Community Sample? For the experiment described below, identify the following: 1. Independent variable; 2. Dependent variable; 3. Control variables; 4. ...
In an experiment, the variable being controlled is called theindependent variable. It is attributed as the cause of change, which an experimenter can manipulate. In an experiment about a fertilizer's effect on plant growth, the independent variable is the fertilizer because it is manipulated. Anot...
In an experiment, we need to control variables to ensure the accuracy of the results. “Control variables” means ___. A. change variables B. keep variables the same C. increase variables D. decrease variables 相关知识点: 试题来源: 解析 B。“Control variables”的意思是控制变量,也就是保持...
What is the control in an experiment? A control in a science experiment is a sample that is not affected by changes occurring from the independent variable. It is meant to establish the validity of the experiment. How do you find the control in an experiment? You find the control in an ...
make the experiment easier C. understand the relationship between variables D. save time 相关知识点: 试题来源: 解析 C。控制变量能帮助我们理解变量之间的关系。选项 A 得到更多结果不准确;选项 B 使实验更容易不是主要目的;选项 D 节省时间也不是控制变量的主要作用。反馈 收藏 ...
The experimenter usually sets the value of a. the independent variable. b. the dependent variable. c. all the extraneous variables. d. none of the variables in the experiment. Write the operational definition, independent variable, and dependent variable for the question, what is t...
Variablesare an important part of science projects and experiments. What is a variable? Basically, a variable is any factor that can be controlled, changed, or measured in an experiment.Scientific experimentshave several types of variables. The independent anddependent variablesare the ones usually ...
In an experiment about the influence of pH on enzyme activity, how can variables be controlled? A. Use different enzymes and different pH values B. Use the same enzyme and different temperatures C. Use the same enzyme and change only the pH value D. Use different E. nzymes and different ...
