counter intuitive as it may seem, data entry keyers that type at a much higher than average rate, also tend to have the lowest error rate. This goes against the conventional wisdom that more speed average words per minute typing leads to more errors. Unlike speeding while driving a car – which anyone can typical data entry error rates do, higher speeds with keyers are a sign of proficiency of the skill, and that proficiency extends to accuracy also. Another average keystrokes per hour confusing aspect in judging the skill of an operator is that many typing tests assess accuracy in a way that doesn’t make sense. The usual way has been to take the typing speed and subtract http://panko.shidler.hawaii.edu/HumanErr/Basic.htm each error (as if it magically disappears) to get at a net speed. For example, a gross typing speed of 40 wpm minus 5 errors equals a net typing speed of 35 wpm, with a 100% accuracy rate implied. The reason this doesn’t make sense is to consider the real world implications of data entered in this manner in a company. The 5 errors do not magically disappear. They happen, only http://www.blog.coleman-data.com/data-entry-speed-and-accuracy-measures/ being corrected when caught – which may or may not take place until damage is done. A better way to assess accuracy is to keep the speed and error data separate and therefore known. This keeps the accuracy data visible to ensure an organization making a hiring decision has the full picture. There is still a problem in comparing a fast data entry employee to an average one as far as accuracy goes, even with both figures known. This is because the surface measures can make it appear that the faster one has less accuracy. An example of this would look something like the following scenario. Average speed : 40 wpm with 3 errors Above average speed: 60 wpm with 4 errors This shows that the above average keyer had more errors (less accuracy). A more accurate way to figure it would be to figure the accuracy as a percentage. The ‘winner’ results would be flipped then as shown below. Average speed: 3/40 wpm = 8% errors (92% accuracy rate) Average speed: 4/60 wpm = 7% errors (93% accuracy rate) So the 60 wpm keyer has not only a better accuracy rate, but completes 50% more work than the average keyer while doing so. Now let us look at thes

Gross WPM Gross, or Raw WPM (Words Per Minute) is a calculation of exactly how fast you type with no error penalties. The gross typing speed is calculated by taking all words typed and dividing by the time error rate it took to type the words in minutes. When calculating typing speed, a "word" is any five characters. For instance, "I love keyboarding, don't you?" would be counted as 6 words (30 characters / 5) and not just 5. This makes sense because typing "deinstitutionalization" obviously should count more than typing "my". Spaces, numbers, letters, and punctuation are all included, but average error rate any function keys such as Shift or Backspace are not included. This makes the number of words easy to calculate. Simply count all typed entries and divide by five to get the number of words typed. To give an example, if you typed 200 characters in 1 minute, your net wpm typing speed would be (200 characters / 5) / 1 min = 40 WPM. If you typed 200 characters in 30 seconds your net speed would be (200/5) / 0.5 = 80 WPM. A Net WPM calculation is preferred for measuring typing speed as opposed to the Gross WPM computation since including mistakes will give a more complete picture of your true typing abilities. However, Gross WPM is used in the calculation of the Net WPM calculation which merits its mention. Net WPM Net WPM is argueably the most useful tool in gauging typing abilities. Since errors play a part in its calculation, it is more a measure of typing productivity than of just typing speed. In other words, a fast but error-prone typist will receive a low

Generally, a typing speed of 40 WPM (Words Per Minute) is considered an average typing speed. An average speed should not be confused with a "minimum speed" that some employers may use as a job requirement - an applicant must exceed the stated minimum speed. Some office jobs may have a higher minimum typing speed requirement than the standard "average" typing speed. What is a good typing speed? A typing speed above 40 WPM (Words Per Minute) is higher than the average score, and over 100 WPM is usually considered a high speed (when it is achieved with zero errors). Why are errors during typing bad? An error is a mistake, and making mistakes in typed correspondence is frowned upon by employers. Just typing fast is not enough, the accuracy of the typist is equally important. The time wasted making corrections from excessive errors far outweighs any advantage from typing that document faster. In a typing test, the test taker is penalized by deducting one WPM per error. It is therefore more productive to correct errors with the backspace key immediately, rather than rushing through the typing exercise just to beat the clock. ©1999-2016 Learn2Type.com, Inc.
