解析spss常用程序

1、讀入數(shù)據(jù)的程序:

DATA LIST LIST
  /id (F3) Interview_date (ADATE10) Age (F3) Gender (A1) 
   Income_category (F1) Religion (F1) opinion1 to opinion4 (4F1).

解釋?zhuān)阂x入數(shù)據(jù)的變量,例如:id為變量名,后面的(F3)表示數(shù)字型的程度為3(可根據(jù)需要設(shè)計(jì)),依次類(lèi)推A1表示字符的長(zhǎng)度為1
BEGIN DATA(開(kāi)始讀入數(shù)據(jù))
150 11/1/2002 55 m 3 4 5 1 3 1
272 10/24/02 25 f 3 9 2 3 4 3
299 10-24-02 900 f 8 4 2 9 3 4
227 10/29/2002 62 m 9 4 2 3 5 3
216 10/26/2002 39 F 7 3 9 3 2 1
228 10/30/2002 24 f 4 2 3 5 1 5
333 10/29/2002 30 m 2 3 5 1 2 3
385 10/24/2002 23 m 4 4 3 3 9 2
170 10/21/2002 29 f 4 2 2 2 2 5
391 10/21/2002 58 m 1 3 5 1 5 3
END DATA.(結(jié)束讀入)

2、對(duì)變量添加名稱(chēng)(簡(jiǎn)單的說(shuō)就是數(shù)據(jù)庫(kù)中變量的意思是什么?)

VARIABLE LABELS
  Interview_date "Interview date"
  Income_category "Income category"
  opinion1 "Would buy this product"
  opinion2 "Would recommend this product to others"
  opinion3 "Price is reasonable"
  opinion4 "Better than a poke in the eye with a sharp stick".

解析:

VARIABLE LABELS

變量名(  Interview_date )  要賦予的變量名稱(chēng)(Interview date)

3、為變量中的數(shù)值添加lable

VALUE LABELS
  Gender "m" "Male" "f" "Female"(對(duì)字符型賦值)
  /Income_category 1 "Under 25K" 2 "25K to 49K" 3 "50K to 74K" 4 "75K+"
  7 "Refused to answer" 8 "Don't know" 9 "No answer"
  /Religion 1 "Catholic" 2 "Protestant" 3 "Jewish" 4 "Other" 9 "No answer"
  /opinion1 TO opinion4 1 "Strongly Disagree" 2 "Disagree" 3 "Ambivalent" 
  4 "Agree" 5 "Strongly Agree" 9 "No answer".

解析:

VALUE LABELS
  Gender "m" "Male" "f" "Female"(對(duì)字符型賦值Gernder表示要賦值的變量名,比如運(yùn)行以后表示“F”代表female,“M”表示Male)

數(shù)據(jù)型的:Income_category 1 "Under 25K" 2 "25K to 49K" 3 "50K to 74K" 4 "75K+"(對(duì)數(shù)值型賦值,Income_category 表示要賦值的變量名,比如運(yùn)行以后表示1代表Under 25K,2表示25K to 49K,依次類(lèi)推)

4、缺失值處理

MISSING VALUES 
  Income_category (7, 8, 9)
  Religion opinion1 TO opinion4 (9).

解析:MISSING VALUES  Income_category (7, 8, 9)(表示將Income_category變量中的7\8\9認(rèn)為是缺失值,可根據(jù)自己的目的處理,自行修改)

5、修改變量的類(lèi)型:

VARIABLE LEVEL 
  Income_category, opinion1 to opinion4 (ORDINAL)
  Religion (NOMINAL).

6、檢查

DISPLAY DICTIONARY.(運(yùn)行即可,看見(jiàn)數(shù)據(jù)庫(kù)的所有信息)

解析:VARIABLE LEVEL  Income_category, opinion1 to opinion4 (ORDINAL)(表示把Income_category,opinion1 to opinion4的變量改為定序變量)可根據(jù)分析的進(jìn)行修改
