What this chart tells us
For the Vocabulary Depth dimension, there is a relationship between occurrence of low-frequency words in your response and your overall TOEFL Speaking score. To earn a high overall TOEFL Speaking score, you probably need to use more "sophisticated" (i.e. low-frequency) words than about 75% of other test takers.
- the Vocabulary Depth score for this response is 26 (i.e. it scored in the 26th percentile)
- 74% of all responses scored higher; 26% of all responses scored lower
- responses with a Vocabulary Depth score of 26 are (weakly) consistent with an overall TOEFL Speaking score in the Limited range
- responses with a Vocabulary Depth score between the 59 and 75 scored in the Fair and the High ranges (i.e. where the blue/green bars overlap)
- the Impact of this dimension is 1/4, meaning there is a weak correlation between Vocabulary Depth and your overall TOEFL Speaking score
