    知識探究(一):普查與抽查像人口普查這樣,對每一個調(diào)查調(diào)查對象都進行調(diào)查的方法,稱為全面調(diào)查(又稱普查)。 在一個調(diào)查中,我們把調(diào)查對象的全體稱為總體,組成總體的每一個調(diào)查對象稱為個體。為了強調(diào)調(diào)查目的,也可以把調(diào)查對象的某些指標的全體作為總體,每一個調(diào)查對象的相應(yīng)指標作為個體。問題二:除了普查,還有其他的調(diào)查方法嗎?由于人口普查需要花費巨大的財力、物力,因而不宜經(jīng)常進行。為了及時掌握全國人口變動狀況,我國每年還會進行一次人口變動情況的調(diào)查,根據(jù)抽取的居民情況來推斷總體的人口變動情況。像這樣,根據(jù)一定目的,從總體中抽取一部分個體進行調(diào)查,并以此為依據(jù)對總體的情況作出估計和判斷的方法,稱為抽樣調(diào)查(或稱抽查)。我們把從總體中抽取的那部分個體稱為樣本,樣本中包含的個體數(shù)稱為樣本量。
