一、多項(xiàng)選擇題（每題2分，共20題）

1.C

解析思路：選項(xiàng)A、B、D都是關(guān)于商務(wù)數(shù)據(jù)分析的正確描述，而選項(xiàng)C錯(cuò)誤地排除了小公司使用數(shù)據(jù)分析的可能性。

2.D

解析思路：數(shù)據(jù)組織是數(shù)據(jù)清洗的一部分，而不是一個(gè)獨(dú)立的步驟。

3.A

解析思路：大數(shù)據(jù)指的是數(shù)據(jù)量巨大，無法使用傳統(tǒng)數(shù)據(jù)處理應(yīng)用進(jìn)行分析。

4.A

解析思路：假設(shè)是在數(shù)據(jù)分析之前對(duì)結(jié)果的一種猜測(cè)。

5.D

解析思路：均值、標(biāo)準(zhǔn)差和中位數(shù)都是描述性統(tǒng)計(jì)的常見指標(biāo)。

6.B

解析思路：商務(wù)儀表板主要用于提供關(guān)鍵績效指標(biāo)的摘要視圖。

7.A

解析思路：預(yù)測(cè)分析使用歷史數(shù)據(jù)來預(yù)測(cè)未來趨勢(shì)。

8.A

解析思路：相關(guān)性衡量了兩個(gè)變量之間的關(guān)系強(qiáng)度和方向。

9.D

解析思路：假設(shè)檢驗(yàn)、回歸分析和聚類分析都是數(shù)據(jù)分析中使用的統(tǒng)計(jì)測(cè)試類型。

10.D

解析思路：初級(jí)數(shù)據(jù)是公司自己收集的，而次級(jí)數(shù)據(jù)是從外部來源獲得的。

11.A
