What is the effect of keeping all variables exept the independent variable the same?
That will result in "replications" of the experiment.
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 are the Difference between endogenous and exogenous variables?
Endogenous variables are important in econometrics and economic modeling because they show whether a variable causes a particular effect. Economists employ causal modeling to explain outcomes (dependent variables) based on a variety of factors (independent variables), and to determine to which extent a result can be attributed to an endogenous or exogenous cause.
What is a casual relationship in math?
A cause and effect relationship between the two variables.
How do you keep control variables constant?
Dependent upon the variables, you need to take into consideration factors that can affect the outcome of the result; what will make the result vary in any way. If this, for example, entails the variable to be kept constant time, you will monitor the time and repeat it throughout the experiment. This is my understanding of constant variables; hope this helped.

What is the meaning of cause and effect hypothesis?
A cause and effect hypothesis is a proposed explanation stating that one phenomenon (the cause) leads to or influences another phenomenon (the effect). It suggests that changes in the cause will result in changes in the effect, allowing researchers to test and analyze relationships between variables.
Is a result and an effect the same?
No. The effect is what happens as a result of something . For instance if you run a stop sign (result) the effect can be an accident. Think cause and effect.

What is the difference between result and effect?
A result is what you get from doing something. An effect is what happens because of that result.
How does the time period or number of variables effect correlation coefficient?
The time period may not affect the correlation coefficient at all. If looking at the correlation between the mass and volume of steel objects, time is totally irrelevant. The effect of the number of variables depends on whether or not the extra variables are related to ANY of the variables in the equation.
How do you know that a variable is really a control variable and what is the property of control variables?
If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.
What have you learned about variables?
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.
What variables can you change that will result in larger beaks?
We need an equation to work with.
