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 a dependent variable in research?
The dependent variable is the variable that the researcher does not control. The researcher will change one variable called the independent variable (ex. temperature, amount of sunlight, amount of food, etc.) and then observe the corresponding dependent variable (ex. reaction of organism, amount of plant growth, swimming speed, etc.)
What is the independent variable?
Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
A researcher performing an experiment introduces changes in an response variable and tries to explain or bring about resulting changes in the explanatory variable?
True
When a researcher cannot tell which variable might be causing an observed effect in an experiment the variables are?
confounded
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.
The independent variable is associated mainly with?
the treatment that the researcher controls directly.

In an experimental design the variable the researcher has control over and that is different for the treatment and control groups is called the?
Explanatory variable apex

What variable did the researcher change during this experiment?
Control Variable
Define internal validity?
Internal validity is higher when you stop confounding variables interfering with the experiment (things that effect the results). Internal validity occurs when a researcher controls all confounding variables and the only variable influencing the results of a study is the one being manipulated by the researcher. This means that the variable the researcher intended to study is indeed the one affecting the results and not something else.
What is the variable being changed by the researcher when designing an experiment?
The manipulated variable I think.
What is the independent variable?
Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
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?
A variable factor.
