Can someone me plz? what is a dependent and independent variable?

Dependent is a variable that can’t tans alone it needs something else to make its data true, independent can stand alone, nothing affects its outcome.

An independent variable is something in an experiment that is being changed. For example, A basketball coach is giving his players new shoes to see if those increase their performance on the court. In the experiment, the coach is giving them new shoes which would be the independent variable.

A dependent variable is a result of the independent variable. For example, the basketball coach changed his player's shoes and their game performance increased drastically. In this experiment, the coach gave them new shoes and their game performance increased. The player's game performance is the dependent variable since it was changed due to the independent variable being the shoe change.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
