N-body studies have demonstrated that large-scale filamentary features should be commonplace in the universe. We use robust statistical methods to quantify the large scale structures in the CfA wedges and similar wedges extracted from N-body simulations. We investigate the significance of features that are visually prominent, e.g. ``the great wall'' using the Minimal Spanning Tree and a bootstrap related method we call shuffling to evaluate the significance levels of the large-scale features. Comparison of the data from surveys with data extracted from N-body simulations allows us to assess the likelihood that the current picture of large-scale structure formation from gravitational instability is sufficient to form the large-scale visual features present in the redshift surveys.
