The following formula is used to calculate the total number of words correct per minute:
\[ WCPM = \frac{TW - M}{T} \]
Where:
\( WCPM \) is the words correct per minute
\( TW \) is the total number of words in the reading
\( M \) is the total number of mistakes made while reading the passage
\( T \) is the total time in minutes
To calculate \( T \), use the formula:
\[ T = m + \frac{S}{60} \]
Where \( m \) is the number of minutes and \( S \) is the number of seconds.
WCPM is an acronym that stands for words correct per minute. It’s a metric used in teaching to understand the reading comprehension of students.
Let's calculate the WCPM for a student who read a 200-word passage in 2 minutes and 10 seconds with 6 mistakes:
Total Words (TW) = 200
Mistakes (M) = 6
Minutes (m) = 2
Seconds (S) = 10
First, calculate the total time in minutes:
\[ T = 2 + \frac{10}{60} = 2.167 \text{ minutes} \]
Then, calculate the WCPM:
\[ WCPM = \frac{200 - 6}{2.167} = 89.53 \]
