This video tutorial explores the association between numerical values, focusing on three key aspects: linearity, direction, and strength. It begins by explaining the difference between linear and nonlinear associations, emphasizing the importance of a straight-line relationship in linear associations. The video then delves into the concept of direction, describing positive, negative, and no correlation scenarios. Finally, it examines the strength of correlations, categorizing them into strong, moderate, and weak based on the scatter of data points around a trend line.
