3. SAMPLE SURVEY
• ”SURVEY” REFER TO MANY DIFFERENT TYPES OR TECHNIQUES OF OBSERVATION
• PROCESS OF SELECTING A SAMPLE OF ELEMENTS FROM A TARGET POPULATION
• WIDELY USED AS A COST EFFECTIVE INSTRUMENT OF DATA COLLECTION.

4. SOME ASPECTS REQUIRING ATTENTION AT THE
PLANNING STAGE ARE:
• OBJECTIVES OF THE SURVEY
• METHOD OF DATA COLLECTION
• QUESTIONNAIRE DEVELOPMENT
• CHOICE OF SAMPLING DESIGN
• PROCESSING OF DATA, AND
• PREPARATION OF REPORT

5. OBJECTIVES OF THE SURVEY
• FOR SURVEY SAMPLING FORMULATING THE OBJECTIVES OF THE SURVEY IS NECESSARY.
• THE SURVEY STATISTICIAN’S FORMULATION OF OBJECTIVES SHOULD INCLUDE THE FOLLOWING:
1. A CLEAR STATEMENT OF THE DESIRED INFORMATION IN STATISTICAL TERMS
2. THE FORM IN WHICH THE DATA SHOULD BE TABULATED
3. THE ACCURACY AIMED AT IN THE FINAL RESULTS
4. COST OF SURVEY

6. METHOD OF DATA COLLECTION
• VARIETIES OF METHODS USED TO COLLECT INFORMATION
• THE METHODS USUALLY ADOPTED FOR COLLECTING PRIMARY DATA ARE:
1. DIRECT PERSONAL INTERVIEW,
2. QUESTIONNAIRES SENT THROUGH MAIL,
3. TELEPHONE INTERVIEW.

7. METHODSOFCOLLECTINGSAMPLES
1. PERSONAL INTERVIEW
• WIDELY USED IN SOCIAL AND ECONOMIC SURVEYS
• THE INVESTIGATOR PERSONALLY CONTACTS THE RESPONDENTS AND CAN OBTAIN THE REQUIRED DATA
FAIRLY ACCURATELY
• THE RESPONSE RATE IS USUALLY GOOD AND THE INFORMATION IS MORE RELIABLE AND CORRECT
• HOWEVER, MORE EXPENSES AND TIME IS REQUIRED TO CONTACT THE RESPONDENTS
2. QUESTIONNAIRES SENT THROUGH MAIL
• ALSO KNOWN AS MAIL INQUIRY
• THE INVESTIGATOR PREPARES A QUESTIONNAIRE AND SENDS IT BY MAIL TO THE RESPONDENTS
• THE METHOD IS SUITABLE WHERE RESPONDENTS ARE SPREAD OVER A WIDE AREA.
• THOUGH THE METHOD IS LESS EXPENSIVE, NORMALLY IT HAS A POOR RESPONSE RATE
3. TELEPHONE INTERVIEW.
• THE POPULATION UNDER THE SURVEY CAN BE APPROACHED BY PHONE
• SURVEYS ON DISTANT PLACES CAN BE DONE

8. QUESTIONNAIRE DEVELOPMENT
• THE INFORMANTS OR RESPONDENTS ARE ASKED PRE-SPECIFIED QUESTIONS
• THEIR REPLIES TO THESE QUESTIONS ARE RECORDED BY THEMSELVES OR BY INVESTIGATORS
• IN THIS CASE, THE INVESTIGATOR IS NOT SUPPOSED TO INFLUENCE THE RESPONDENTS
• IN THE SCHEDULE APPROACH, THE EXACT FORM OF THE QUESTIONS TO BE ASKED ARE NOT
GIVEN TO THE RESPONDENTS

9. CHOICE OF SAMPLING DESIGN
• ONE OF THE MOST IMPORTANT STEP IN THE PROCESS OF PLANNING SAMPLE SURVEYS
• PRINCIPLE GENERALLY ADOPTED IN THE CHOICE OF A DESIGN IS EITHER REDUCTION OF
OVERALL COST OR REDUCTION OF MARGIN OF ERROR OF THE ESTIMATES
• CHOICE OF SAMPLE UNITS, METHOD OF SELECTING SAMPLE AND DETERMINATION OF SAMPLE
SIZE ARE SOME OF THE IMPORTANT ASPECTS IN THE CHOICE OF PROPER SAMPLE DESIGN.

10. PROCESSING OF DATA
• FIRST TASK WHICH IS OF PRIMARY IMPORTANCE IS THE REDUCTION OF COLLECTED DATA INTO
MEANINGFUL TABLES
• TABLES SHOULD BE PRESENTED ALONG WITH THE BACKGROUND INFORMATION SUCH AS THE
OBJECTIVE(S) OF THE SURVEY, THE SAMPLING DESIGN ADOPTED, METHOD USED FOR DATA
COLLECTION AND TABULATION
• SUBJECT ANALYSIS TO BE TAKEN UP AFTER PREPARING SUMMARY TABLES, SHOULD INCLUDE
CROSS TABULATION OF DATA BY THE MEANINGFUL, GEOGRAPHICAL, ECONOMY,
DEMOGRAPHIC OR OTHER BREAKDOWNS TO STUDY THEIR RELATIONSHIP AND TRENDS AMONG
VARIOUS CHARACTERISTICS

11. PREPARATION OF REPORT
SOME POINTS WHICH SERVE AS GUIDELINES IN THE PREPARATION OF SAMPLE
SURVEY REPORTS ARE GIVEN BELOW:
• INTRODUCTION & REVIEW OF LITERATURE
• OBJECTIVE(S)
• SCOPE
• SUBJECT COVERAGE
• METHOD OF DATA COLLECTION
• SAMPLING DESIGN AND ESTIMATION PROCEDURE
• TABULATION PROCEDURE PRESENTATION OF RESULTS
