Differences
Management Decision Problem- A problem that needs to make a decision about something. It relates with a problem
that is faced by the management or decision maker. It asks what the decision maker needs to do. The management
decision problem is action oriented. It is concerned with the possible actions the decision maker can take. Hence a

Q3. Discuss with the help of examples the four key levels of measurement. What mathematical
operations/statistical techniques are and are not permissible on data from each type of scale?
(Meaning of Measurement scales-2 marks, Types of Measurement scales with examples-5 marks, Mathematical
operations/statistical techniques-3 marks) 10 marks
Answer.
Meaning of Measurement scales
Campbell defines measurement scale as “the assignment of numbers to represent properties.”
Levels of Measurement
Measurement may be classified into four different levels, based on the characteristics of order, distance and origin.
Q4. Processing of data involves editing, coding, classifying and tabulating. Explain each of these steps by taking
an appropriate example.
(Explanation-6 marks, Examples-4 marks) 10 marks
Answer.
STEPS:
Identifying the data structures
In the data preparation step, the data are prepared in a data format, which allows the analyst to use modern analysis
software such as SAS or SPSS.

b. One tailed and two tailed tests
c. Type I and Type II error
d. One way and two way analysis of variance
e. Descriptive and inferential analysis of data
Differences (2 marks each) 10 marks
Answer.
a. Null hypothesis and Alternative hypothesis
In the context of statistical analysis, we often talk null and alternative hypothesis. If we are to compare method A with
method B about its superiority and if we proceed on the assumption that both methods are equally good, then this
assumption is termed as null hypothesis. As against this, we may think that the method A is superior, it is alternative
hypothesis. Symbolically presented as:
Q6. a. What is Chi-square test of goodness of fit? What precautions are necessary while applying this test? Point
out its role in business decision making.
b. Two research workers classified some people in income groups on the basis of sampling studies. Their results
are as follow:
Show that the sampling technique of at least one research worker is defective.
