What analysis method can be used to estimate the general pattern of change?

Visual analysis is a method that is particularly effective for estimating the general pattern of change in data collected over time, often in the context of single-case research or applied behavior analysis. This method involves the examination of graphed data to look for trends, levels, and variability within the data points. By visually interpreting these trends, practitioners can identify whether there is a consistent increase or decrease in behavior or performance, allowing for an immediate understanding of how an intervention may be affecting the subject.

Visual analysis focuses on individual data sets, making it useful for assessing the effectiveness of interventions and making real-time adjustments based on observable outcomes. This contrasts with statistical approaches, which may require complex calculations and assume normally distributed data, potentially obscuring individual patterns of change. Thus, visual analysis directly addresses the need to monitor and evaluate patterns of change in a straightforward and accessible manner.
