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) What is this table called?
(b) State the null hypothesis and the alternate hypothesis.
(c) What is the decision rule?
(d) Determine the value of chi-square.
(e) Make a decision on the null hypothesis. Interpret the result.

Answer:
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.
