This opens the door to a sensitivity analysis strategy whereby the analyst can start with a small number of points (screening-wise) and then – depending on the results – possibly increase the numeral of points up to compute a fully quantitative measure.
While the error rates for verbs, adjectives, and pronouns decreased, the error rates for nouns and numerals increased.
Because discriminability was dependent on magnitude for dots but not for numerals, the difference between two choices corresponding to a given perceptual increment depends on magnitude for dots, but not for numerals; i.e. the perceptual value of numerals increases almost linearly with increasing magnitude, but the perceptual value for dot arrays falls off with magnitude (Fig. 4a).
This is consistent with a study on a chimpanzee who learned to match numbers of dots to Arabic numerals, who also did not show increasing reaction times for increasing numbers of dots (Murofushi 1987).
Adult humans estimating large numbers of items show increasing errors for proportionately smaller differences, but our accuracy using numerals is almost entirely independent of number magnitude, i.e. it is linear.
These plots confirm that for dots the performance curves are distinctly broader for increasing numerosities, but this broadening with magnitude is almost absent for numerals.
His oxygen intake, measured by numerals that fluctuate with literally each breath — 90, 87, 91, 85, 89, 92 — is increasing.
Hazard ratios provide information about the direction of an association (a numeral over 1 indicates an increased risk with the positive variable, and a numeral under 1 indicates a decreased risk) as well as the magnitude of the risk.
"Investment in creativity gives a company considerably more security than, for example, its assets, age, liquidity, growth or financial strategy," he writes, adding that the numeral two even increases the risk.
Finally, economics data from [14] on the percentual growth of the global economy 1951 1999, corrected for the population growth, were used (fig. 5A; n = 49) in addition to demographics data on the percentual numeral increase of the global population 1951 2009 (fig. 5B; n = 59; from [14]).
