Answer:
1. What is the importance of knowing the relationship of the variables with each other?
ANSWER: Knowing the relationship between variables enables prediction. If we know how two variables are related, we can predict scores on one variable from the other variable.
2. Why are variables so important?
ANSWER: Variables are important to understand because they are the basic units of the information studied and interpreted in research studies. Researchers carefully analyze and interpret the value(s) of each variable to make sense of how things relate to each other in a descriptive study or what has happened in an experiment.
3. Explain: Correlation does not allow us to go beyond the data that is given.
ANSWER: A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases. An example of positive correlation would be height and weight. Taller people tend to be heavier.
