   Characters Per Minute (CPM): Characters Per Minute (CPM) measures the total number of characters
                 (including spaces and punctuation) typed correctly and incorrectly within one minute.
                Formula: CPM is calculated by dividing the total number of characters typed by the time taken in minutes.
                Example: If you type 300 characters in 1 minute, your CPM would be 300/1=300 CPM.

                 Net Characters Per Minute (Net CPM): Net Characters Per Minute (Net CPM) represents the typing
                 speed excluding characters typed incorrectly. It focuses only on accurately typed characters.
                Formula: Net CPM is obtained by subtracting the rate of characters typed with errors (per minute) from
                 the overall CPM.
                Example: If your CPM is 300 and you made errors equivalent to 50 characters in 1 minute, your Net CPM
                 would be {300−(50/1)} = 250 Net CPM.
                 Keystrokes Per Minute (KPM): Keystrokes Per Minute (KPM) measures the total number of keystrokes
                 (key presses) made within one minute, whether they were correct or incorrect.
                Formula: KPM is calculated by dividing the total number of keystrokes by the time taken in minutes.
                Example: If you press keys 400 times in 2 minutes, your KPM would be 400/2=200 KPM.
                 Net Keystrokes Per Minute (Net KPM): Net Keystrokes Per Minute (Net KPM) represents the typing
                 efficiency excluding keystrokes made in error. It measures the rate of accurately executed keystrokes.
                Formula: Net KPM is obtained by subtracting the rate of keystrokes made in error (per minute) from the
                 overall KPM.
                Example: If your KPM is 200 and you made errors equivalent to 30 keystrokes in 2 minutes, your Net KPM
                 would be {200−(30/2)} = 185 Net KPM.
              These metrics are important for assessing typing proficiency, focusing not only on speed but also on accuracy,
              which are essential skills for various tasks such as writing, data entry, and coding.

              Typing Accuracy
              Typing accuracy measures the percentage of correct entries out of the total entries typed. It’s an essential
              metric for evaluating how accurately someone types without errors.
              Formulas for Typing Accuracy Calculation:
                 Accuracy in Words: Accuracy in words measures the percentage of correctly typed words out of the total
                 number of words typed, excluding errors.
                Formula: Accuracy (%)= (1− (Words with errors/ Total number of words) ) × 100

                Example: If you typed 100 words and 5 were incorrect, your accuracy would be (1−(5/100)) × 100=95%.
                 Accuracy in Characters: Accuracy in characters calculates the percentage of correctly typed characters out
                 of the total number of characters typed, excluding errors.
                Formula: Accuracy (%)= (1− (Characters with errors/ Total number of Characters) ) × 100
                Example: If you typed 500 characters and 20 were incorrect, your accuracy would be (1−(20/500)) × 100=96%.
                 Accuracy in Keystrokes: Accuracy in keystrokes measures the percentage of correctly executed keystrokes
                 out of the total number of keystrokes made, excluding errors.

                Formula: Accuracy (%)= (1− (Incorrect Keystrokes/ Total number of keystrokes) ) × 100
                 Example: If you typed 400 keystrokes and 10 were incorrect, your accuracy would be (1−(10/400)) × 100=97.5%.
              Sometimes it’s convenient to evaluate the typing accuracy in the Errors (percentage errors) as shown below:
                 Error in Words: Errors in words measure the percentage of words typed incorrectly out of the total number
                 of words typed.
                Formula: Error (%)= (Words with errors/ Total number of words ) × 100

                Example: If you typed 100 words and 5 were incorrect, your error rate would be (5/100) × 100=5%.
