What is the constant variable in investigation of fungi growth mold?
The variables that you keep the same between the control and experimental groups are the constant variables.
What is the difference between control samples and test experimental samples?
It calculates the difference between each set of pairs, and analyzes that list of differences. The P value answersthis question: If the median difference in the ... If your samples are small and there are no tied ranks, Prism calculates an ... The whole point of using a paired test is to control for experimental.
Variables that are always different between the experimental and the control groups are?
Independent variables. If the treatment has no effect , the dependent variables for both the control and experimental group may be the same. cw: In some studies, there is no specific control group. For instance, in a drug study where subjects are given a random amount of the drug (from 0 up to some presumed safe level) then you cannot easily tell what the "experimental" group is -- you can't compare everyone else to the two subjects who got a placebo (0 mg/kg). You can tell whether the treatment is having a linear effect, etc.
What is meant by saying a hypothesis must be testable. This developing a hypothesis?
* something testable * have to have tools * dependent and independent variables * groups (control and experimental) * something "do-able"
What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
What is the constant variable in investigation of fungi growth mold?
The variables that you keep the same between the control and experimental groups are the constant variables.
The experimental group and the?
Learn about the difference between the control group and the experimental group in a scientific experiment.
What do you call the variable that must remain the same between two groups?
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
What type of variables is experimental control?
Independent variable
What is the difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
In a controlled experiment what term is used to describe the many factors that might be different between the experimental and control groups?
variables
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
The purpose of blocking in experimental design is?
the control for multiple variables in a experiment
