Is the slope of a line positive when doing linear regression if the correlation coefficient is negative?
No, the slope of a line in linear regression cannot be positive if the correlation coefficient is negative. The correlation coefficient measures the strength and direction of a linear relationship between two variables; a negative value indicates that as one variable increases, the other decreases. Consequently, a negative correlation will result in a negative slope for the regression line.
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
If you are doing a science fair project on a fruit battery what would be the independent and dependent variable be?
the independet variable would be the type of fruits used and the dependent variable would be the electricity they generate.
What is definition and examples of dependent variable and independent variable?
I'm doing a science project on if fingerprint patterns are inherited? what is the control, independent variable and dependent variable? An ''independent variable is a ''variable which is presumed to affect or determine a dependent ''variable. independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated.'''''' Example; In price and sales relationship one can manipulate price to check its effect on sales, so sale is dependent and price is independent variable.
What is a controlled variable in experimental psychology?
A controlled variable is the thing that is kept consistent in between trials of doing an experiment. e.g: time is kept the same or kept consistent...
In a correlation between student cumulative GPA and the number of hours spent on school work each week which one would be the x variable?
When one is likely to be the cause of the other, you generally make it the x variable. Y is the dependent variable. In this case, the correlation would indicate that more time doing schoolwork leads to a higher GPA. Schoolwork is the x, or independent variable. GPA is the y variable, because grades depend on doing schoolwork.
Is the slope of a line positive when doing linear regression if the correlation coefficient is negative?
No, the slope of a line in linear regression cannot be positive if the correlation coefficient is negative. The correlation coefficient measures the strength and direction of a linear relationship between two variables; a negative value indicates that as one variable increases, the other decreases. Consequently, a negative correlation will result in a negative slope for the regression line.
Is smoking a quantitative variable?
Smoking is not a variable. It is an act of doing something. Types of cigarettes is a qualitative variable.
What is the one factor that is changed our tested by the person doing the investigation?
The independent variable is the factor that is changed or tested by the person doing the investigation. It is the variable that is manipulated to observe its effect on the dependent variable.
When doing linear regression if the correlation coefficient is positive the slope of the line is negative?
False.
Do you change the numerator when you are doing a dependent variable?
No.
What is the dependent variable in an non-experiment project which describes the water cycle?
If you are not doing an experiment, there is no variable.
What is a independent varieable?
Independent variable (Manipulated Variable) is a variable that is purposefully changed by the experimenter (the person who is doing the experiment) *the first part of the experiment question is the independent variable.
Is it legal to scatter ashes anywhere in Illinois?
You would need the permission of the owner of the property where you are doing so.
