What type of correlation occurs when both variables increase together?

• A. Positive Correlation
• B. Negative Correlation
• C. Zero Correlation
• D. Co-Variables

Answer: (A)

A positive relationship occurs when both variables increase together. As one variable rises, the other tends to rise as well, which shows an upward pattern on a scatterplot. This contrasts with a negative correlation, where one variable increases while the other decreases, and with zero correlation, where there’s no consistent pattern between the variables. Co-variables isn’t a type of correlation. For example, more hours spent studying often relates to higher exam scores, illustrating a positive correlation.
