Question

If you need to do a research design report about the trade war between China and US. Whom would you survey to find first-hand information concerning your research statement?Why did you choose this group of people to focus on? What is the population for your survey? Why did you choose this population? What is your sample size? How your sample will be chosen? How the term random in relation to your survey? Will you need a mathematical formula to choose your sample? Why or why not? Is there a confidence level associated with your sample? How will your data be collected? How will your data be analyzed? Why did you choose that format for analysis? How will your data be interpreted? Will distribution and frequency tables and/or Chi Square play a role in your analysis?

Answer 1

Research question: Did the trade war between China and US affect your business?

Interested people: Chief finance officers of the corporates who operates within the frame of the sharemarket.

CFOs are the key people involved in supplying financial data inputs to the internal and external users of the financial information.
Population: All the CFO of the major corporations in all the countries who trades internally with their global presence in atleast 3 countries across the world.
I have chosen this population who are really having the financial information and responsibility sharing the financial information for the interest of the shareholders, to their employees, and to the general public.
Sample size will be determined using an estimated proportion of there will be more than 50% will say yes to my questionair at an estimated error 5% for a confidence level of 95%.
I will chose the samples randomly from the list of all the CFO's of major corporations of my interest using random number generator algorithm or excel.
Random in my sample selection process means that all the CFO's will have equal chance of getting participated in an face to face interview.
Yes I need a mathematical formula to calculate my sample size that is n, equal to the product of the Z value squared and the variance, sigma squared, divided by the square of the sampling error, e.
Yes, I am using 95% confidence level, that will have an Type I error of 5% risk of rejection null if it is true.
Data collection will be done in a face to face interview in very confidential manner, keeping person privacy strictly confidential.
Data will be analyzed against an hypothesize or estimated true population of 50% of the CFO says No against Yes.
The 2 way contingency table model will be the best one to analyze the all the possibilities of the occurrence of the event of interest in an very independent way and joint independent events, and the mutual independent event's proportions can be analysed using this type model.
Interpretation of the moments of the sample data related to the sample proportions against the true populations will be done to make a conclusion.
Yes, the distribution of the data shall be normal, no deviations allowed to ensure or avoid any biased estimations of the sample proportions. Table plays a key role in modeling the data. Chi-square test will be used to analyze the fittness test of the model.
