The formula to calculate the Error Rate is:
\[ ER = \frac{TW}{TE} \]
Where:
Let's say a student read 1000 words and made 25 errors. The error rate would be calculated as follows:
\[ ER = \frac{1000}{25} = 40 \]
So, the error rate is 40.
An error rate, in the context of reading, is a ratio of the total words read to the total errors made while reading. This is used when scoring and analyzing a running record of an individual.
