A correlation in a scatterplot indicates a relationship between two variables. If the points trend upward from left to right, it shows a positive correlation, meaning as one variable increases, the other does too. Conversely, a downward trend indicates a negative correlation, where one variable increases while the other decreases. The strength of the correlation can vary; closely clustered points suggest a strong correlation, while widely scattered points imply a weak correlation. No apparent trend indicates little to no correlation.
