【摘要】：正1.資料的表達與描述:用均數(shù)±標準差表達近似服從正態(tài)分布的定量資料,用中位數(shù)及四分位間距表達呈偏態(tài)分布的定量資料;用統(tǒng)計表時要合理安排縱橫標目,注意不要犯主謂倒置的錯誤;用統(tǒng)計圖時所用統(tǒng)計圖的類型應(yīng)與資料性質(zhì)相匹配并使數(shù)軸上刻度值的標法符合數(shù)學(xué)原則;用相對數(shù)時分母不宜小于20,要注意區(qū)分百分率與百分比。2.統(tǒng)計分析方法的選擇:對于定量資料,應(yīng)根據(jù)所采用的設(shè)計類型、資料所具備的條件和分析目的選用合適的統(tǒng)計分
[Abstract]:Regular 1. Data expression and description: the quantitative data from normal distribution were expressed with mean 鹵standard deviation, and the quantitative data with skew distribution were expressed with median and quartile spacing. When using statistical tables, we should arrange the vertical and horizontal items reasonably, pay attention not to make the mistake of subject-predicate inversion, and the types of statistical charts used in statistical charts should match the nature of the data and make the scaling method of scale value on the number axis conform to the mathematical principle. When using the relative number, the denominator should not be less than 20, we should pay attention to distinguish percentage and percentage. 2. Selection of statistical analysis methods: for quantitative data, appropriate statistical scores should be selected according to the type of design used, the conditions of the data and the purpose of analysis
