What is the name in an experimental design where the variable in which the researcher is trying to elicit a change?
Response Variable

In an experiment to determine absolute value with charles's law you heat a syringe of air in a beaker of water and record temp and how much the gas expanded but what is the control variable?
the pressure is same
What are the differences between independent and dependent variables?
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
How do you determine if two variable are correlated?
what what!
What is dependant variable?
A dependant variable is a term used in science to identify the response that is measured in an experiment. When a researcher conducts an experiment, he is interested in the outcome, defined as the dependent variable.
What variable systematically manipulated by the researcher?
The independent variable is the one which the researcher controls and manipulates. On a graph this is the 'x' axis.
What variable did the researcher change during this experiment?
Control Variable
Can a correlated study determine when there is lack of a relationship between two variables?
Sure. If you can observe that when variable A changed, variable B didn't change, and this happens repeatedly, that is a good indication that there is no relationship between those variables.
What is negatively correlated?
Two variables are negatively correlated when the slope of the best-fit line that is drawn on the scatter plot with the independent variable on the x-axis and the dependent variable on the y-axis is negative.
A variable of which a researcher is not aware but which might be causing changes in the response variable is called a variable?
lurking
What is the variable being changed by the researcher when designing an experiment?
The manipulated variable I think.
What is the name in an experimental design where the variable in which the researcher is trying to elicit a change?
Response Variable
What is the type of variable that a researcher wants to keep from affecting an experiments outcome?
Extraneous variable
What is a single factor manipulated by a researcher?
