Detailed explanation-1: -Television viewing was linked to lower academic scores as well as math and language skills, the researchers found, while video gaming was linked to poorer grades. The researchers did say the study only found an association–it didn’t prove one causes the other.

Detailed explanation-3: -The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Detailed explanation-4: -Question: What’s an independent variable? Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
