The dividing-center method entails drawing an oval around scatterplot points, except for outliers, to identify data points that deviate significantly from the trend.
The method for drawing a trend line for the data in a scatterplot in which an oval is drawn around all the points except the outliers is known as the dividing-center method.
This method involves drawing an oval that encompasses most points, highlighting the outliers that fall outside the oval. By visually segregating the outliers, the dividing-center method helps in identifying data points that significantly deviate from the trend.
An example of this is drawing an oval around the scatterplot points and marking the outlier (x=65, y=175) that lies beyond the specified boundaries.
