Small sample bias 小樣本偏誤
To avoid sampling bias , they restricted their analysis to one group of animals ? the bivalve molluscs ? that fossilise well 為了防止取樣的偏頗,他們將分析的對(duì)象限制在一類(lèi)化石記錄保存完備動(dòng)物? ?雙殼類(lèi)軟體動(dòng)物。
This made a small - scale sampling to develop a database of school teacher ' s information literacy through , used regression analysis to determine the weight distribution of evaluation indicators by means of minimum sampling bias , and set up a set of quantitative indicators for the evaluation of teacher ' s information literacy 摘要本文認(rèn)為通過(guò)小范圍的教師樣本可獲取關(guān)于教師信息素養(yǎng)量化評(píng)價(jià)指標(biāo)和總的教師信息素養(yǎng)數(shù)據(jù),運(yùn)用回歸分析法最小化樣本偏差可獲取各評(píng)價(jià)指標(biāo)對(duì)應(yīng)的合理的權(quán)重分布,從而建立一個(gè)適應(yīng)各學(xué)校實(shí)際情況的教師信息素養(yǎng)量化評(píng)價(jià)指標(biāo)體系。
