Variable View

It is the sheet where you define the Variable of the Data that you have, The Variable View Consists of the Following Column heading,

  • Name: Enter the Unique Identifiable and Sorting Variable Name, Eg: In the Data of Students, The Variables can be ID, Sex, Age, Class, Etc, Note : This will not allow any special character or Space while describing the variables of the Data, and Once you enter the First Variable, Immediately you can see SPSS generating all the other information regarding how you want to set that Variable that you have entered to be,
  • Type: You Can change the Type of Variable, Whether Numeric, Alphabets or Alpha Numeric by selecting the respective Type in this column, this will restrict the use of any other type being used under this variable column
  • Width : Defines the Character Width this Variable Should allow, Especially helpful while entering Mobile number which allow only 10 character
  • Decimal: Defines the Decimal point you required to display, Eg: Used in case of percentages
  • Label: Since the Name Column Doesn’t allow you to use any Special Character or Space, here you can give any name as an Label for that Variable you wanted to assign
  • Value : This is to define/ Label a Value Wherever you see in the Data, Eg: You can Label “0” in the data as ABSENT for Exam, So when you find 0 in the data, it will be labeled as ABSENT for Exam, You Can also Label the Employee ID Number with their Name, So that Using the value Label Switch Button you can view the Name of the employee, but in report the Name will not appear, only the EMP ID number will appear, This helps in reading the data better in data view
  • Missing : You can mention the Data which you don’t want the SPSS to consider while analyzing, Like “0” Value is considered as Absent, so for analysis it will neglect “0” if its mentioned in Missing, which will be helpful in Mean, Mode Etc,
  • Align : You can mention the alignment of the data in the data sheet, Left, Right of Middle,
  • Measure: This is where you will define the measure of the Variable that you have entered, Whether Scale, Ordinal or Nominal type of Variable

Note:Shortcut – You can copy the Variable Type and Paste in the Next row, if it’s almost the Same type of Variable, Like Subjects Marks – Science, Maths, English, History – All these will have the same Type except for change in Name and Label

After defining all the variables of the data, Once you Click on the DATA View Sheet, You can See the Labels entered by you as the Columns Label,

Data View

The Data View is a Spreadsheet which contains rows and columns, The Data Can be entered in the Data View Sheet Either Manually or the data can be imported from the data file, SPSS can read the data file in any of the one format, which can be Excel, Plain text files or relational (SQL) Databases, Before importing the excel sheet change the excel file format to (.xls)

Note: SPSS can read the data file better in numeric than the String (Text), So it’s always better to convert most of the data as Numeric Variables Data, Eg: In case of Survey they Use more of Yes/ no, Good/Average/Bad, Male/Female, – Here in all these cases you can use codes in data file like 1 – Yes, 2 – No; Also make sure that the Excel data is arranged in such a way that Rows always contain Responses from Different people and Columns contains responses to different questions;

Statistical Test Using SPSS

Quick Data Check

Before using any statistical test, It’s always advisable to do a data check to know how the data has been distributed and clearly defined, whether the missing values are neglected etc, Data Check is usually done using Charts, so that any abnormalities can be easily detected and data can be corrected,

Histogram – is widely used to check the data in case of One Variable Tests – Creating an histogram is already been explained;

Scatter Plot Chart – is used for Two Variable Tests:

  • Click Graphs……… Select Legacy Dialogs……. Select Scatter/Dot
  • Select the Simple Scatter Chart
  • Click define
  • You will Find the X axis and Y axis for Comparison
  • Drop the Variable for X axis and Y axis respectively
  • Click Ok
