What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
How many experimental variables should you have?
There's no "Limit", but the less you have, the better the experiment.
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.
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"
Factors that are varied during an experimental procedure are called?
Variables
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
What is experimental grouping?
experimental group or set ups with same variables. OMG i hate scince
What are experimental variables?
things that you change every trial
What type of variables is experimental control?
Independent variable
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
What is the Difference between experimental and non experimental?
Experimental research involves manipulating variables to observe the effects on an outcome, while non-experimental research does not involve manipulating variables. Experimental research allows researchers to establish cause-and-effect relationships, whereas non-experimental research focuses on observing and describing relationships between variables without manipulation.
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
The purpose of blocking in experimental design is?
the control for multiple variables in a experiment
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
Blocking in experimental design is useful because it?
controls for multiple variables in an experiment.
How many experimental variables should you have?
There's no "Limit", but the less you have, the better the experiment.
