Research Methodology Question Paper Discussion July,2007 Team 2
Section B – Question 9 (a) Explain Type 1 & Type 2 Error in Hypothesis Testing. Give an example of a situation error where Type 1 Error is more serious than Type 2 Error.
Answer 9 (a) Type 1 Error: Type 1 Error is when we reject H when it is actually true. It means a rejection of a hypothesis which should have been accepted. Type 2 Error is when we accept H when it is not true. It means the acceptance of a hypothesis which should have been rejected.
An example of a situation where Type 1 Error is more serious than a Type 2 Error is when doing a research for testing a new drug for children. The an example of a situation where Type 1 Error is more serious than a Type 2 Error is when doing a research for testing a new drug for children. The H for example would say that the new drug brings about skin lesions on the baby’s skin. H says that the new drug does not cause any skin lesions. And we accept H when the tests show that H should be accepted. This could be fatal.
Content Analysis Consists of analysing the contents of documentary materials and the content of all other verbal materials, which can be either spoken or printed. Is measurement through proportion. Measures pervasiveness & that is sometimes an index of the intensity of the force. Is a central activity whenever one is concerned with the study of the nature of the verbal materials.
A review of research in any area, for instance, involves the analysis of the content of research articles that have been published. The analysis may be at a relatively simple level or e a subtle one P-110(C.R.KOTHARI second edition)
Projective Techniques Projective techniques(or what are sometimes called as indirect interviewing techniques) for the collection of data have been developed by psychologists to use projections of respondents for inferring about underlying motives, urges, or intentions which are such that the respondent either resists to reveal them or is unable to figure out himself.
Cont….. In projective techniques the respondent in supplying information tends unconsciously to project his attitudes or feelings on the subject under study For gaining an insight into sensitive issues To get an idea of the respondents inner feelings. P-107(C.R.KOTHARI second edition)
Presentation of Research Report Should be typed or printed Should have a uniform font Findings of the research study should be placed under appropriate headings and sub headings Leave ample space between the lines. Split larger para into smaller paragraphs. Use bullet points to list specific points
Cont… Ensure that appropriate labels are assigned to every table, figure, and graph that appears in the report. Business Research methods(ICFAI)
Case Study The objectives of the study would be to find the technological competitiveness of India vis a vis the countries of the world. The sampling frame would be stratified simple random sampling. The advancements in scientific research in the country has a significant impact on it industrial competitiveness.
