2. Reliability of managerial decisions Quality of data [Ex: GIGO]
Data are facts, figures and other relevant materials, past and present
serving as basis for study and analysis
Importance:
- Base, Inferences, Findings, Testing hypothesis, Construction – scale, tables
Classifications:
I. Primary & Secondary
II. Documentary Sources, Personal sources & Library Source
Choice factors
- Nature & scope, Money, Time, Accuracy, Status & Availability of
investigator/researcher
3. Primary data
Collected for the first time
Information generated to meet the specific requirements of the investigation at hand
Methods:-
1. Observation 7. Mail survey
2. Experimentation 8.Projective techniques
3. Simulation 9. Sociometry
4. Interview 10. Focus group discussion
5. Use of telephone 11. Content analysis
6. Panel method
4. Secondary Data
Already published
Data compiled by some other agency than the user
Modify for researcher’s use
Check before collecting primary data
Analysis of this attempts to re-interpret the original data set in relation to a new research
question
For Identify & define problem, develop an approach to the problem, formulate research
design, questions, hypothesis testing, interpretations
Internal Found within the organisation/unit
- Part of company’s record
Ex: Sales record, Cost information, Credit outstanding, Monthly collection report etc.
External From outside the company/unit
Ex: Government publications, foreign government publications, journals, publications of trade
associations, books, magazines, newspapers, annual reports, publications from

6. Precautions
Minute scrutiny of available data
Reliability Who? Where? Methods? Time? Any bias? Accuracy etc.
Suitability Terms? Units? Object, scope, nature enquiry
Adequacy Level of accuracy

Advantages & Disadvantages
11. Survey
Method used for collecting primary data based on verbal or written
communication with a representative sample of individuals or
respondents from the target population
Used for both descriptive and causal research
Usually conducted by an interviewer interacts with respondents
Fact-finding study
Phenomena cannot be observed directly – Questionnaire Response
error/bias, Hesitant to reply, Interviewer error etc.
Features & Objectives
12. Types of surveys
Cross – sectional surveys - – No. of characteristics from sample
elements are collected and analysed, relationship found.# single point
of time
Longitudinal Surveys - Event/occurrence is measured again and again
over a period of time, To observe continuity & change in response in
due course.
Trend Studies : Sample of same population; not same people. Long period
of time.
Cohort studies : Particular population studied more than once .Ex: 2018-21
Batch
Panel studies :
1. True Panel- Same panel, Same variables, Different time
2. Omni Bus – Same panel, Different variables, Different time
13. Census Method:
- Whole population is studied
- Time, money & energy
- Universe is small – Good method
Sample Method
- Small part/sample of universe is studied
Sample survey, Fax survey, Internet survey, Mail
survey- Industrial & consumer, Media studies,
Multiple surveys & E-mail survey

Skilled Interviewer
To discover underlying motives & desires
20. Questionnaire & Schedule
Bogardus- “A questionnaire is a list of questions sent to
a number of persons for them to answer. It secures
