本發(fā)明涉及一種網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度的評(píng)估方法,屬于社會(huì)調(diào)查、網(wǎng)絡(luò)技術(shù)的
技術(shù)領(lǐng)域:
。
背景技術(shù):
:隨著互聯(lián)網(wǎng)絡(luò)的發(fā)展,網(wǎng)絡(luò)問(wèn)卷調(diào)查日益興起并廣泛應(yīng)用于各個(gè)行業(yè)和領(lǐng)域。與傳統(tǒng)的紙質(zhì)問(wèn)卷調(diào)查相比,網(wǎng)絡(luò)問(wèn)卷調(diào)查具有調(diào)查組織便捷、節(jié)省成本、快速回收、數(shù)據(jù)管理高效等優(yōu)點(diǎn)。但同時(shí)網(wǎng)絡(luò)問(wèn)卷調(diào)查的數(shù)據(jù)質(zhì)量也備受質(zhì)疑,存在由于網(wǎng)絡(luò)問(wèn)卷調(diào)查答題者無(wú)視問(wèn)卷內(nèi)容而默從回答、敷衍回答或無(wú)回答導(dǎo)致問(wèn)卷可信度降低,致使數(shù)據(jù)質(zhì)量較低的問(wèn)題。針對(duì)此類問(wèn)題,相關(guān)
背景技術(shù):
較多著眼于對(duì)無(wú)回答問(wèn)題的識(shí)別和控制,對(duì)于默從回答、敷衍回答導(dǎo)致的低可信度問(wèn)題缺乏便捷有效的評(píng)估方法。另有一些數(shù)據(jù)質(zhì)量評(píng)估方法如主觀和客觀相結(jié)合的方法,從多個(gè)維度進(jìn)行評(píng)估,面向數(shù)據(jù)質(zhì)量的綜合測(cè)量,存在工作量大、耗時(shí)多、針對(duì)性不強(qiáng)、不夠便捷等不足。技術(shù)實(shí)現(xiàn)要素:本發(fā)明是在設(shè)計(jì)答題計(jì)時(shí)功能基礎(chǔ)上,比較網(wǎng)絡(luò)問(wèn)卷調(diào)查答題者的答題總用時(shí)和參考答題總用時(shí)、以及各題答題用時(shí)和各題參考答題用時(shí)的關(guān)系,構(gòu)建網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度評(píng)估指標(biāo)體系和評(píng)價(jià)標(biāo)準(zhǔn),判定問(wèn)卷的可信度。本發(fā)明所述問(wèn)題是以下述技術(shù)方案實(shí)現(xiàn)的:首先設(shè)計(jì)網(wǎng)絡(luò)問(wèn)卷調(diào)查答題頁(yè)面計(jì)時(shí)功能,設(shè)定參考答題總用時(shí)和各題答題參考用時(shí);然后統(tǒng)計(jì)答題總用時(shí)和各題答題用時(shí),計(jì)算評(píng)估指標(biāo)數(shù)值,并根據(jù)可信度評(píng)估標(biāo)準(zhǔn)對(duì)指標(biāo)數(shù)值區(qū)間值進(jìn)行評(píng)估,判定問(wèn)卷可信度。上述方法包括以下步驟:a、設(shè)計(jì)網(wǎng)絡(luò)問(wèn)卷調(diào)查答題頁(yè)面的計(jì)時(shí)功能。(1)設(shè)計(jì)答題總計(jì)時(shí)功能:設(shè)定“開始”和“結(jié)束”答題按鍵,進(jìn)入答題頁(yè)面點(diǎn)擊“開始”按鍵,提交問(wèn)卷時(shí)點(diǎn)擊“結(jié)束”,從點(diǎn)擊“開始”到點(diǎn)擊“結(jié)束”之間的時(shí)間為答題總用時(shí)T。(2)設(shè)計(jì)各題答題計(jì)時(shí)功能:某道題答題時(shí)間ti為該題一次或多次作答(含第一次作答和修改作答)用時(shí)的總和,單次答題時(shí)間為上一次點(diǎn)擊(其他題或該題前一次)答案點(diǎn)擊至該題答案點(diǎn)擊之間的時(shí)間tij,T與ti的關(guān)系、ti與的tij關(guān)系見(jiàn)公式1及公式2。T=∑ti(1)其中T為答題總用時(shí),ti為第i道題答題用時(shí),tij為第i道題第j次答題用時(shí)。b、以快速讀完問(wèn)卷題目文字表述的用時(shí)為依據(jù),設(shè)定網(wǎng)絡(luò)問(wèn)卷調(diào)查參考答題總用時(shí)T’和各題答題的參考用時(shí)ti’,T’和ti’的關(guān)系見(jiàn)公式3;T'=∑ti'(3)其中T’為參考答題總用時(shí),ti’為第i道題參考答題用時(shí)。c、計(jì)算評(píng)估指標(biāo)值,判定網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度。(1)網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度評(píng)估指標(biāo)分為2個(gè):答題總用時(shí)評(píng)估指標(biāo)A(公式4)和有效答題數(shù)量評(píng)估指標(biāo)a(公式5、6)。其中A為答題總用時(shí)評(píng)估指標(biāo),T為答題總用時(shí),T’為參考答題總用時(shí),ti為第i道題答題用時(shí),ti’為第i道題參考答題用時(shí),ai為第i道題答題用時(shí)與第i道題參考答題用時(shí)的比值,a為有效答題數(shù)量評(píng)估指標(biāo),n為題目數(shù)量。(2)建立網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度評(píng)估標(biāo)準(zhǔn),指標(biāo)區(qū)間值與評(píng)估結(jié)果如下:A≧1,可信;A<1,不可信;ai≧1,取值1;ai<1,取值0;a≧50%,可信;a<50%,不可信。(3)判定網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度:A≧1,a≧50%:可信卷;A<1,a<50%:不可信卷(廢卷);A<1,a≧50%:可疑卷;A≧1,a<50%:可疑卷。具體實(shí)施方式本發(fā)明以廈門市居民出行方式問(wèn)卷調(diào)查為案例,說(shuō)明網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度評(píng)估方法的實(shí)施方法。具體而言,包括以下步驟:a、編制廈門市居民出行方式問(wèn)卷,問(wèn)卷包括10道題,見(jiàn)表1。b、以快速讀完問(wèn)卷題目文字表述的用時(shí)為依據(jù),設(shè)定問(wèn)卷調(diào)查參考答題總用時(shí)和各題答題的參考用時(shí),見(jiàn)表2。表1廈門市居民出行方式問(wèn)卷調(diào)查表表2問(wèn)卷答題參考時(shí)間c、進(jìn)行問(wèn)卷調(diào)查四次,采用計(jì)時(shí)表對(duì)每一次問(wèn)卷答題進(jìn)行計(jì)時(shí)。各次的答題總用時(shí)和各題答題用時(shí)見(jiàn)表3。表3問(wèn)卷調(diào)查用時(shí)d、計(jì)算四次問(wèn)卷調(diào)查的可信度評(píng)估指標(biāo)值,包括答題總用時(shí)評(píng)估指標(biāo)和有效答題數(shù)量評(píng)估指標(biāo),見(jiàn)表4。表4問(wèn)卷調(diào)查可信度評(píng)估指標(biāo)計(jì)算結(jié)果e、評(píng)估四次問(wèn)卷調(diào)查的指標(biāo)計(jì)算結(jié)果,判定問(wèn)卷可信度,判定出可信卷、可疑卷或不可信卷(廢卷),見(jiàn)表5。表5問(wèn)卷調(diào)查可信度判定結(jié)果指標(biāo)評(píng)估結(jié)果可信度判定問(wèn)卷調(diào)查一A>1,a>50%可信卷問(wèn)卷調(diào)查二A>1,a<50%可疑卷問(wèn)卷調(diào)查三A<1,a>50%可疑卷問(wèn)卷調(diào)查四A<1,a<50%不可信卷(廢卷)本發(fā)明所建立的網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度評(píng)估方法,是在設(shè)計(jì)答題計(jì)時(shí)功能的基礎(chǔ)上,分析網(wǎng)絡(luò)問(wèn)卷調(diào)查答題者的答題用時(shí)和參考答題用時(shí)關(guān)系,構(gòu)建評(píng)估指標(biāo)體系和評(píng)價(jià)標(biāo)準(zhǔn),實(shí)現(xiàn)對(duì)網(wǎng)絡(luò)問(wèn)卷調(diào)查可信度的識(shí)別和評(píng)估。本方法將為提高網(wǎng)絡(luò)問(wèn)卷調(diào)查的可信度和數(shù)據(jù)質(zhì)量提供一種快速、便捷且有效的方法。當(dāng)前第1頁(yè)1 2 3
