Data Entry, Keyboarding Skills and Office Productivity Basics
Keyboarding
Touch typing uses the home row: A S D F for the left hand, J K L ; for the right, with index fingers on F and J (the raised bumps) and thumbs on the space bar. Each finger owns a fixed column and returns home after every stroke. Never look at the keys - accuracy first, speed follows.
Gross speed = words typed ÷ minutes. Net speed = gross − (errors ÷ minutes). Accuracy % = (characters typed − errors) ÷ characters typed × 100.
Data entry
A source document is what you key from. Validation checks data as it is entered (field type, range, mandatory fields, check digits). Verification checks after entry that the keyed data matches the source - double entry (two operators, then compare) is the strongest method. Use Tab between fields and save with Ctrl+S.
Office productivity basics
Word processor = letters and reports; spreadsheet = calculations; presentation = slides; DBMS = structured records. Each saves in its own format but can export to PDF.
Worked example
An operator types 240 words in 3 minutes with 9 errors. Gross = 240 ÷ 3 = 80 wpm. Net = 80 − (9 ÷ 3) = 80 − 3 = 77 wpm. Accuracy = (240 − 9) ÷ 240 × 100 = 96.25%. If the target is 40 wpm net, the operator clears the speed bar but should still be corrected on accuracy, because errors create rework.
Traps
- Dividing errors by words instead of minutes when computing net speed.
- Using Caps Lock for a single capital instead of Shift.
- Treating validation and verification as the same thing.
- Closing the file without saving.
