things that you change every trial
Variables
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
Experimental variables are factors being tested or measured in a scientific experiment. They can be categorized as independent variables (manipulated by the experimenter), dependent variables (respond to the changes in the independent variable), and controlled variables (kept constant to prevent interference).
experimental group or set ups with same variables. OMG i hate scince
Independent variable
experimental control
Non-experimental research is done by examining data from other research studies and compiling observations. There are no original experiments conducted in this type of research. Experimental research is done by conducting original experiments.
the control for multiple variables in a experiment
All variables except one, the experimental variable, are kept constant in an experiment.
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.

experimantal variable is ewan koh! hahhahahaahah! epal
