摘要：本文通過分析數(shù)據(jù)編制頻數(shù)分布表、計(jì)算均值、方差、標(biāo)準(zhǔn)差、進(jìn)行正態(tài)分布的擬合度檢驗(yàn)等過程, 用正態(tài)分布的性質(zhì)分析兩個(gè)班的成績及分析兩個(gè)班學(xué)習(xí)成績的平均分?jǐn)?shù)和離散程度的差異情況, 說明了概率統(tǒng)計(jì)方法在教育教學(xué)中的應(yīng)用。同時(shí), 通過調(diào)查研究語文與政治學(xué)科之間的關(guān)系、外語成績是否與學(xué)習(xí)興趣有關(guān)等例子, 為教育決策、教育管理提供有意義的信息。 關(guān)鍵詞：概率統(tǒng)計(jì)； 標(biāo)準(zhǔn)差； 正態(tài)分布
Abstract: In this paper, with the analysis of the frequency distributed table, the calculation of the mean value, the variance and the standard deviation, the test of the fitting degree of normal distribution, the differences between the mean value and dispersion degree of the grade of two classes are analyzed in this paper according to the properties of normal distribution, which demonstrates the application of probabilistic method in education and teaching. At the same time, some examples are discussed such as the relationship between Chinese and Politics and the influence of interest on the grade of foreign language in order to provide some useful information for education decision and education management. Key words: probability and statistics；standard deviation； normal distribution |
