Sampling technology market analysis business leaders will provide good decisionmaking role. The use of different market research of different sampling techniques, there is little use of sampling techniques in the enterprise has and summarized, so I think in terms of the need to review and summarize. This article focused on the analysis of different sampling techniques and characteristics of the different technologies are introduced, and then based on theoretical knowledge and practical application in the enterprises surveyed, the abstract knowledge visualization reality, and further understand the practical value sample injection technique , so that everyone in the importance of statistical sampling technology in the enterprise to understand the actual survey.Keywords:samplingtechniques。Simplerandomsampling.Stratifiedsampling.Systemsampling。Thepracticalapplication目 錄摘 要 IAbstract II1 引 言 12 抽樣技術(shù)的簡(jiǎn)單分類和概念 1 簡(jiǎn)單隨機(jī)抽樣的概念 1 分層抽樣的概念 1 系統(tǒng)抽樣 23 市場(chǎng)調(diào)查中的簡(jiǎn)單隨機(jī)抽樣應(yīng)用 2 簡(jiǎn)單隨機(jī)抽樣的特點(diǎn) 2 簡(jiǎn)單隨機(jī)抽樣基本公式 2 簡(jiǎn)單隨機(jī)抽樣中估計(jì)量的性質(zhì) 3 估計(jì)量的無(wú)偏性 3 估計(jì)量的方差 4 估計(jì)量的置信區(qū)間 4 簡(jiǎn)單隨機(jī)抽樣的實(shí)際運(yùn)用 54 市場(chǎng)調(diào)查中的分層抽樣應(yīng)用 7 分層抽樣的特點(diǎn) 7 分層抽樣的性質(zhì) 7 分層抽樣在市場(chǎng)調(diào)查中實(shí)際運(yùn)用 75 市場(chǎng)調(diào)查中的系統(tǒng)抽樣的應(yīng)用 9 系統(tǒng)抽樣的特點(diǎn) 9 系統(tǒng)抽樣在市場(chǎng)調(diào)查中的應(yīng)用舉例 106 結(jié)束語(yǔ) 11參考文獻(xiàn) 121 引 言在經(jīng)濟(jì)全球化下,市場(chǎng)是千變?nèi)f化的,而在市場(chǎng)的變化過(guò)程中也有某種規(guī)矩,我們要掌握其市場(chǎng)的變化才能去更好的應(yīng)對(duì),如果我們被市場(chǎng)主引而不是我們?nèi)ヒ龑?dǎo)市場(chǎng),那么我們被淘汰是在所難免的。我們要掌握市場(chǎng)必須去調(diào)查它進(jìn)而分析它,從中得出來(lái)結(jié)論。這樣我們就知道市場(chǎng)調(diào)查的重要性和進(jìn)行調(diào)查的必要性。市場(chǎng)是
