Dummy variable as an independent variable?
An independent variable is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable. It may be something that is already there and is fixed, something you would like to evaluate with respect to how it affects something else, the dependent variable like color, kind, time. Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Independent variable in measuring heart rate?
Time is the independent variable.
How would you write a dependent and independent variable for growth of crystals in a faster rate depending on temperature?
Dependent variable: growth of crystals Independent variable: temperature.
What does dependant variable mean?
See link for the Wikipedia article. The dependent variable is sometimes called response variable, or outcome variable. During what year of school, K thru 12, do kids experience the greatest average change in height (or weight)? You are "manipulating" what year of school a child is in. You aren't making any changes on this-- this is just your independent variable. You are going to measure height change for each child, so a starting and ending measure is needed. Height is the dependent variable.
What is a ratio that compares the amount of change in the dependent variable to the amount of change in the independent variable?
rate of change. :)
What is a dependent and indenpendent variale?
A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable. Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.

What are the independent variable and the dependent variable?
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
What is the ratio that compares the amount of chage in a dependent variable to the amount of change in an independent variable?
Rate of Change

rate of change. :)
What is a ratio that compares the amount of change in the dependent variable to the amount of change in the independent variable?
rate of change. :)
What is the dependent variable in an experiment to determine whether drinking caffeinated soda increases pulse rate?
The pulse rate, since it's dependent on the quantity of caffeine, which is the changeable, independent variable.
What is the physical significance of gradient define?
The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
