Step by step
Solved in 2 steps
- an independent variable is the variable measured in an experiment. True or FalseA properly designed experiment contains the following: positive and negative controls and experimental conditions. positive control and experimental conditions. positive and negative controls control and experimentalIn the experiment described above, state what each of these parts of the experiment was: Independent variable Dependent variable Control group Experimental group One controlled variable
- What variable is the one that you can manipulate or change? It is sometimes called experimental variableWhat do you call a sample that goes through all the steps of an experiment but is not exposed to the experimental variable? control group dependent variable independent variable all variables/groups are exposed to the experimental variableWhat is the independent variable of the experiment?
- The null hypothesis is: That the measured value is zero That the proposed model is not correct and the measured factors have no effect on the pattern That the proposed model is correct and perfectly explains the pattern That the experiment is null and voidIn the experiment described above, specifically state what each of these parts of the experiment was: Independent variable Dependent variable Control group Experimental group One controlled variableWhy is it important to have a control for an experiment?
- What is the dependent variable of the experiment?In a controlled experiment all of the variables are kept the same in order to contsistent. there is only one variable there is change for these kind of studies and it is known as variableThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.
