1) are subtracted from scores of a second variable.
2) are related to scores of the second variable.
3)ause the second variable to change.
4) have no relationship with the scores of a second variable.

Answer 1

A correlation is a relationship between two variables where changes in one variable correspond to changes in another variable. The strength and direction of the relationship can be measured using a correlation coefficient.

Step-by-step explanation:

A correlation is a relationship between two variables in which changes in one variable are related to changes in the other variable. This means that as one variable changes, the other variable changes as well. A correlation coefficient is used to measure the strength and direction of the relationship. It is represented by the letter r and can range from -1 to +1. A positive correlation means that the variables move in the same direction, while a negative correlation means they move in opposite directions. The correlation coefficient can help determine the strength of the relationship. A value closer to 1 or -1 indicates a stronger relationship, while a value closer to 0 indicates a weaker relationship.
