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.
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 the difference between dependent asnd independent variables?
The independent variable is the one that the person doing the experiment changes themself. The dependant variable is the one that is recorded as results. For example, if investigating the effect of water on the rate of photosynthesis, you would change the amount of water and record how the rate of photosynthesis changes. Therefore, the amount of water is the independent variable and the rate of photosynthesis is the dependant 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. :)
When measuring the breathing rate of fish over time the variable is independent or dependent?
independent

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.
A researcher is measuring the heart rate of subjects as an index of anxiety in this study the heart rate is?
In this study, the measuring of the heart rate is an operational definition of anxiety.
What are you measuring when you count the pulsations of the carotid artery?
You are measuring heart rate.

What does independent variable means?
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.
What is the munipluated variable pulse heart rate?
pulse rate in legs
