Distinct patterns around a trend line can often be attributed to seasonal variation, such as increased sales during the holiday season or decreased travel during the winter months. Poor underlying data or statistical anomalies would likely result in inconsistent or erratic data points, while dummy variables are used to control for specific factors in a regression analysis and would not necessarily cause distinct patterns around a trend line.
