Answer to Question 1

If an experimenter wanted to see if level of depression affected some behavior, the researcher would manipulate the depression level in participants to see if behavior changed. In this case, depression level would be the IV, the manipulated variable..
If the experimenter wanted to see if some manipulation affected a person's level of depression, the researcher would manipulate an IV and see the result in terms of a person's depression level. In this case, depression would be a DV, or an outcome behavior.

Answer to Question 2

In an experiment, the independent variable (IV) is the variable that the experimenter manipulates in order to see if it behaviors change when the level of the IV changes. The dependent variable (DV) is the measurement made relating to the effect of the IV. That is, the value of the DV (i.e., the measurement of a behavior) will vary as the value of the IV varies when the IV has a causal relation to the DV.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
