Along with radiocarbon dating on charcoal remains from human - made fires, these analyses yielded a much more precise estimate for the age of sediments surrounding artifacts at various depths.

Misliya Cave on Israel's Mount Carmel has yielded what its discoverers regard as a partial Homo sapiens jaw with an estimated age of between around 177,000 and 194,000 years old.

Measuring the ratio of potassium - 40 to argon - 40 yields a good estimate of the age of that.

Because of skewness and the ordered categorical nature of our variables, we estimated α within a structural equation model framework, which resulted in higher α coefficients.20 Our ω reliability analyses yielded results consistent with previous studies reporting ω reliabilities for preschool and school - age SDQs.9, 16

Several studies have addressed the validity of the parent - reported SDQ in school - aged samples, predominantly confirming the intended 5 - factor structure.5, 6 A 3 - factor configuration of externalizing (conduct problems and hyperactivity), internalizing (emotional and peer problems), and prosocial factors has also been proposed and suggested for use in epidemiologic studies and in low - risk populations.7, 8 The internal reliability of SDQ subscales has been predominantly examined by using Cronbach's α, a measure of the interrelatedness of items; however, α estimates are a lower bound for reliability and is often underestimated.9 A meta - analytic review reported weighted mean α coefficients extracted from 26 studies that showed generally modest reliabilities for parent reports (0.53 < α < 0.76).10 McDonald's ω, which estimates the proportion of a scale measuring a construct, typically yields higher reliability estimates but has rarely been used to assess reliability of the SDQ.
