order of magnitude

n. pl. orders of magnitude
1. An estimate of size or magnitude expressed as a power of ten: Earth's mass is of the order of magnitude of 1022 tons; that of the sun is 1027 tons.
2. A range of values between a designated lower value and an upper value ten times as large: The masses of Earth and the sun differ by five orders of magnitude.

order of magnitude

n
(Statistics) the approximate size of something, esp measured in powers of 10: the order of magnitude of the deficit was as expected; their estimates differ by an order of magnitude. Also called: order

In fact, data show that, even before they enter elementary school, children from disadvantaged backgrounds are behind their more advantaged peers in basic competencies such as number-line ordering and magnitude comparison (Rathburn and West 2004).

Each 60s exposure image was dark-field subtracted using the relevant nightly dark-field image, and the magnitude of CQ Cep determined by differential photometry using AstroArt 5.0 and a 10.08 V magnitude comparison star (TYC 3991-1480-1) together with a 10.62 V mag check star (TYC 3991-2054-1).

Four components of number sense/number competence deemed most important by cognitive psychologists include: (a) magnitude comparison (Booth & Siegler, 2006), (b) strategic counting (Geary, 2004), (c) the ability to solve simple word problems (Jordan et al., 2009), and (d) retrieval of basic arithmetic facts (Jordan, Hanich, & Kaplan, 2003).

It has been suggested that magnitude comparison (numerical and non-numerical) relies on similar mechanisms (Moyer & Landauer, 1967; Walsh, 2003).

For each usable image, the magnitude of the SN was determined by differential photometry using AstroArt 5.0 against a nearby 13.615 V magnitude comparison star (designated 000BKC-232 in the photometry table for the AAVSO SN 2011dh finder chart).

When it was near the limit of vision, the variable's colour was quite unobtrusive, so a magnitude comparison was readily made, even if its actual meaning may not have been too certain!
