Does the explanatory variable cause changes in the response variable in a valid sample?
No. It may appear to cause the change because the changes are correlated. However, it is quite possible that changes in both variables are caused by some third, possibly unknown, variable.No. It may appear to cause the change because the changes are correlated.

How are variables related?
variables are all related because they can equal to any number
How are correlation and causation the simliar?
Correlation and causation are similar in that both involve relationships between two variables. In correlation, changes in one variable are associated with changes in another, while causation implies that one variable directly influences the other. However, correlation does not imply causation; just because two variables are correlated does not mean that one causes the other. Understanding this distinction is crucial for accurate analysis and interpretation of data.
What does the statement 'correlation does not imply causation' mean?
The statement "correlation does not imply causation" means that just because two variables are correlated—meaning they change together—it does not necessarily mean that one variable causes the change in the other. Correlation can arise from various factors, including coincidence, confounding variables, or reverse causation. Therefore, establishing a cause-and-effect relationship requires further investigation beyond mere correlation.
How is the correlation imperfect?
Correlation is considered imperfect because it measures the strength and direction of a relationship between two variables but does not imply causation. Factors such as outliers, non-linear relationships, or the influence of a third variable can distort the correlation coefficient, leading to misleading interpretations. Additionally, correlation only captures linear associations, meaning that even if two variables are correlated, their relationship may not be consistent across all ranges or contexts.

In what ways does correlation differ from causation?
Correlation is a statistical relationship between two variables, while causation implies that one variable directly influences the other. Just because two variables are correlated does not mean that one causes the other.
What are the shortcomings of correlation?
One shortcoming is the danger of assuming that because 2 variables are highly correlated then one must have caused the other. Correlations alone can never support this assumption.
How are motors and generators examples of energy changing forms?
They are because they can.
What do dependent and independent variables represent in science?
In science, independent variables are variables that you control the change of, to see how somethings changes as a result of changing these variables. Dependent variables are variables that change because the independent variables are changed, but you don't change directly. A good example of this would be an experiment where you're measing how cold a glass of water gets after putting in different amounts of ice in it and wating 5 minutes. The independant variable would be the amount of ice you put into each glass, because that's what you're directly changing. The dependent variable is how cold each glass gets, because that's the result you're trying to see by changing the independent variable - it changes because something else changes. Additionally, when graphing, independent variables are put on the x-axis (horizontal line), and dependent variables are put on the y-axis (vertical line).
Are correlation and causation the same thing?
No, correlation and causation are not the same thing. Correlation means that two variables are related in some way, while causation means that one variable directly causes a change in another variable. Just because two variables are correlated does not mean that one causes the other.
What is the meaning of confounding in statistics?
In statistics. a confounding variable is one that is not under examination but which is correlated with the independent and dependent variable. Any association (correlation) between these two variables is hidden (confounded) by their correlation with the extraneous variable. A simple example: The proportion of black-and-white TV sets in the UK and the greyness of my hair are negatively correlated. But that is not because the TV sets are becoming colour sets and so my hair is loosing colour, nor the other way around. It is simply that both are correlated with the passage of time. Time is the confounding variable in this example.
What's the difference between correlation and causation?
Correlation is a relationship between two variables where they change together, while causation is when one variable directly causes a change in another variable. Just because two things are correlated does not mean that one causes the other.
What is the meaning of the word correlation?
Correlation refers to a statistical measure that shows the extent to which two or more variables change together. A positive correlation indicates that the variables move in the same direction, while a negative correlation means they move in opposite directions. Correlation does not imply causation, meaning that just because two variables are correlated does not mean that one causes the other.
