2012年5月一天某時(shí)連云港市各區(qū)縣的可吸入顆粒物數(shù)值統(tǒng)計(jì)如表:

區(qū) 縣東海贛榆灌云灌南連云區(qū)海州開發(fā)區(qū)新浦
可吸入顆粒物(mg/m30.150.150.150.150.180.180.030.14
則這8個(gè)區(qū)縣該日這一時(shí)刻的可吸入顆粒物數(shù)值的極差是________.

試題答案

0.15

試題解析

根據(jù)極差的公式:極差=最大值-最小值.找出所求數(shù)據(jù)中最大的值0.18,最小值0.03,再代入公式求值.

解答:由題意可知,數(shù)據(jù)中最大的值0.18,最小值0.03,

所以極差為0.18-0.03=0.15.

故答案為0.15.

點(diǎn)評(píng):本題主要考查極差的求法極差反映了一組數(shù)據(jù)變化范圍的大小,求極差的方法是用一組數(shù)據(jù)中的最大值減去最小值.
