The formula to calculate the Type-Token Ratio (TTR) is:
\[ \text{TTR} = \frac{\text{TYP}}{\text{TOK}} \]
Where:
The Type-Token Ratio (TTR) is a measure of lexical diversity within a given text. It is calculated by dividing the total number of unique words (types) by the total number of words (tokens) in the text. A higher TTR indicates greater lexical diversity.
Let's consider an example:
Using the formula to calculate the Type-Token Ratio:
\[ \text{TTR} = \frac{150}{1000} = 0.1500 \]
This demonstrates that with 150 unique types and 1000 total tokens, the Type-Token Ratio would be 0.1500.
