Question.1.
A social scientist sampled 140 people and classified them according to income
level and whether or not they played a state lottery in the last month. The
sample information is reported below. Is it reasonable to conclude that playing
the lottery is related to income level? Use the .05 significance level.

a.Contingency table
b. There is no
Question.2.
What is of more value to the corporate world –basic, fundamental, or applied
research? Justify your reasoning!
Answer:Fundamental research provides generally-applicable insights. For
instance, the extinction risk criteria used to produce the IUCN Red List of threatened
and endangered species are based in large part on fundamental,
generally-applicable models of stochastic population dynamics developed by Russ
Lande (Mace et al. 2008). Mace et al. (2008) discuss at length the reasons for
this, which are not limited to lack of species-specific knowledge. But it is
true that, if you lack detailed, system-specific knowledge, you do want
general, broadly-applicable insights to be able to fall back on.
Question.3.
Distinguish between secondary and primary methods of data collection. Is it
possible to use secondary data methods as substitutes of primary methods?
Justify your answer with suitable illustrations.
Answer:Primary data is raw information collected by researchers for a specific
purpose. Secondary data is information obtained by studying the reports of
other researchers.
When researchers conduct primary research,
they are collecting data in response to a specific question, or in accordance
with a specific objective. They may conduct surveys or focus groups. They may
run experiments, or record direct
Question.4.
What is a systematic sample? How is it selected? What are the advantages and
disadvantages of a systematic sample?
Answer:As a statistical sampling method, systematic sampling is simpler and more
straightforward than random sampling. It can also be more conducive to covering
a wide study area. On the other hand, systematic sampling introduces certain
arbitrary parameters in the data. This can cause over- or under-representation
of particular patterns.
Examining Systematic Sampling
Question.5.
Discuss the applications of rating scales in various functional areas of
management.
Answer:The modern technology has brought in sea changes and transformed the
organisational structure, working and culture. Computers and computer
programmes have flooded into the organisations of all kinds and types giving no
chance to escape from their influence. They are widely used in human resource
management.
Safety and Health:Safety and health at
