A dependent variable is non manipulative and is affected by the manipulations of the independent variable. In the case given, the different levels of family stress like high and low can be siad as different levels of a dependent varible i.e. stress. So, family stress can be a dependent variable but not the levels of stress
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.
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.
in any graph on horizontal axis we keep the independent variable and on vertical axis the dependent variable. similarly in stress strain diagram the strain is independent variable and stress is dependent variable so due to this reason strain is kept on x-axis and stress is kept on y-axis.
You might be thinking of a stress fracture; a fracture of a bone caused by repeated (rather than sudden) mechanical stress.
First
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.

In children exposed to terrorism, the terrorism would be the independent variable because it is the cause of the post traumatic stress. The post traumatic stress would be the dependent variable because it would not have happened without the terrorism.

The independent variable in this hypothesis is having a pet. It is the variable that is being manipulated or changed to observe its effect on stress levels.
a. dependent
An example of an intervening variable is stress, which can impact the relationship between hours of sleep and academic performance. In this case, stress mediates the relationship by influencing both the amount of sleep a person gets and their academic performance.
A manipulated variable is the variable that has been changed in the experiment. A responding variable is the variable that has been kept through the whole experiment.
The second.
yeah it can affect anyones stress levels.
Massage is a way of relaxing and lowering stress levels. Studies have proven that people tend to have lowered stress levels after being massaged. A massage chair would indeed aid you in the reduction of stress levels.
