How to calculate typing speed and accuracy in a typing app.
When you take our free typing test, you will find some typing equations and formulas that are used to calculate your typing statistics.
A calculation of how fast you type is called Gross, or Raw WPM.The gross typing speed is calculated by taking all words typed and dividing them by the time it took to type them in.
A "word" is any five characters."I love keyboarding, don't you?"6 words would be counted and not just 5.It makes sense that "deinstitutionalization" should count more than "my".Functions such as Shift or Backspace are not included.
It's easy to calculate the number of words.If you divide by five, you can get the number of words typed.If you typed 200 characters in 1 minute, your net wpm typing speed would be 40 WPM.If you typed 200 characters in 30 seconds, you would have a net speed of 200/6.
If you want to measure typing speed, a Net WPM calculation is the way to go since it will give you a complete picture of your typing abilities.Gross WPM is used in the calculation of the net wpm calculation.
Net WPM is used the most to gauge typing abilities.Since errors play a part in its calculation, it is more of a measure of typing productivity than just typing speed.A fast but error-prone person will receive a lower net typing speed than a slower but more accurate person.
It makes sense because proof-reading and correcting errors take up more time than just typing a passage correctly.Errors being missed during proof-reading and making their way into the final product is a result of less mistakes.
Net WPM is calculated by subtracting the amount of errors you left in per minute, also known as the error rate.If you divide the number of errors by the time you typed them, you can calculate the error rate.If you typed for two minutes with a gross typing speed of 80 WPM and left in 8 mistakes, your error rate would be 8 errors per minute.76 WPM is the net typing speed.Your typing speed goes down when you make a mistake.
The hard part is deciding which types of errors should be counted.There are two types of errors.
The first impulse is to count all errors, however there are two strong arguments as to why uncorrected errors should be punished.
Fix mistakes and cause brief pauses, but function keys like the delete key take time to press and do not count as a key entry.The time penalty is already built into the process of fixing a mistake.The inherent time penalty makes it hard for the typist to correct their mistakes in the first place.typists should not be discouraged from fixing mistakes as they are typing, but they should be encouraged to do so.Errors left uncorrected are more damaging than errors fixed immediately.
Take the case of many corrected errors.A typing speed of 20 WPM is assumed for a one minute test.The 20 errors that were made were immediately corrected.We calculate the net speed as 0 WPM if we deduct the error penalty.An error-free length of text was obviously typed, but a typing speed of 0 WPM suggests nothing was ever typed.If the mistakes were not corrected, one-fifth of a passage would be a mistake and the resulting text would not be useful.If they hadn't corrected 20 errors, they would have typed faster than 20 WPM.The two points prove that only uncorrected errors should be punished.The percentage of correct entries out of the total entries typed is called accuracy typing accuracy.The number of correct characters typed divided by the total number will be used to calculate this.If you typed 90 out of 100 characters correctly, you would have 90 percent accuracy.All errors, whether corrected or not, should be counted in the accuracy calculation.The calculation is more live than typing speed and shows the likelihood that the next character will be typed correctly.
The percentage of correct entries out of the total entries typed is called typing accuracy.The number of correct characters typed divided by the total number will be used to calculate this.If you typed 90 out of 100 characters correctly, you would have 90 percent accuracy.
