WHAT IS the independent variable in Total cost equals fixed cost plus variable cost?
Total Cost (T) = Fixed Cost (F) plus Variable Cost (V) or T = F + V. The dependent variable is T because as F & V change, T depends on the values of F & V. The independent variables (plural; two) are F & V. F and V change independent of T. You can also think of the above as cause (independent) and effect (dependent). The cause of F & V changing has the effect of T changing. So, in the above equation, there are two independent variables; F & V.
What does a variable stand for in math?
A variable is a very important thing when you are doing an experiment. These are things that have an effect on the experiment. There are three categories of variables in math:The controlled variable: variable the never changesThe manipulated variable: variable that does changeThe responding variable: the result of the experiment
What is moderating variable?
Moderation occurs when the relationship between two variable depends on a third variable. The third variable is referred to as the moderate variable or simply the moderator
What is the ability to neutralize the effect of one variable in order to assess the relationship between two other variables?
makeing the correlation spurious
Does a regression model imply causation?
No it doesn't. Cause and effect is not demonstrated with regression, it only shows that the variables differ together. One variable could be affecting another or the affects could be coming from the way the data is defined.
What is the effect of keeping all variables exept the independent variable the same?
That will result in "replications" of the experiment.
What variable do you decide to change?
I will change a single independent variable at a time while keeping all other variables constant to accurately measure its effect on the dependent variable in an experiment.
What is the part of an experiment that you keep the same?
The part of an experiment that you keep the same is called the "control variable." This variable is used as a baseline for comparison to measure the effect of changing other variables. Keeping the control variable constant helps to ensure that any changes observed in the experiment are a result of the manipulated variable and not other factors.
What statement best describes a controlled experiment?
A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant, in order to observe the effect on another variable (dependent variable). This allows researchers to determine a cause-and-effect relationship between the variables being studied.
What is one condition in an experiment that changes while all the others remain constant?
The independent variable is the condition that changes in an experiment while all the other variables remain constant. The purpose of changing this variable is to observe its effect on the dependent variable.
Identify the variables that you need to control and the variable that you will change?
To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.
What happens during a controlled experiment?
In a controlled experiment, a researcher manipulates one variable (independent variable) to observe the effect on another variable (dependent variable), while keeping all other variables constant. This allows the researcher to establish a cause-and-effect relationship between the variables being studied. Control groups are used to compare the results with the experimental group.
What are cause and effect variables?
Cause variables are factors that directly influence or produce an effect on another variable. Effect variables are outcomes or results that are influenced by the cause variables. Understanding the relationships between cause and effect variables helps to analyze and predict how changes in one variable impact another.
Why cant you draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled?
If none of the variables are constant (or controls) you have no idea which variable or combination of variables caused the effect.
What factor remains fixed in an experiment?
The factor that remains fixed in an experiment is the independent variable. This variable is deliberately controlled or manipulated by the experimenter to observe its effect on the dependent variable, while keeping all other variables constant.
What what does it mean to control variables?
Controlling variables means keeping certain factors constant in an experiment to isolate the effect of the independent variable on the dependent variable. This practice helps ensure that any observed changes in the outcome can be attributed to the independent variable rather than other extraneous factors. By controlling variables, researchers can enhance the reliability and validity of their results.
In an experiment what variable do scientist control?
In an experiment, scientists control the independent variable, which is the factor that is deliberately changed or manipulated to observe its effect on the dependent variable. By keeping other variables constant, researchers can isolate the relationship between the independent and dependent variables. This control helps ensure that any observed changes in the dependent variable are directly due to the manipulation of the independent variable.
