Open the original- What it measures
- The article cites Strong's report, A Comparative Experiment in Simplified Keyboard Retraining and Standard Keyboard Supplementary Training (1956), published by the U.S. General Services Administration. The report was not available online for this guide.
- What it does not show
- A sample of ten per group is small. The result is a single study by one author, so it does not settle the question alone.
