Resumen
The premise of this follow-up sister study to “Measuring the Frequency Occurrence of Handwriting and Handprinting Characteristics” was to collect a representative population sampling of numerals and assess how many participants utilize each of the predetermined characteristics as found in their specimens. A total of 1410 handwriting specimen forms were collected from across the United States and pared to 1025 to obtain a proper representative sample of the U.S. adult population based on the same demographics used in the original 2017 study. This study provides frequency of occurrence proportions and 95% confidence limits for 25 handwritten numeral characteristics. A total of 277 intercharacter pairs of handwritten numeral characteristics were cross-analyzed for interdependence. The results were that 72.92% of all intercharacter pairs had a coefficient of correlation between -0.2 and +0.2 in this study
