What is their significance in research? Explain with examples.Develop five demographic questions to measure gender, age, years of experience, level of education, and ethnicity. Identify the level of measurement used for eachHow would you define a variable? What is the difference between a dependent and independent variable? Do you think both variables are used in every research? Explain why or why not. Provide examples.**What is the importance of statistics in business decision making? Describe a business situation where statistics was used in making a decision.What are the four data measurement scales? Provide two examples and explain the importance of each in business research.****Week 2 Discussion Questions****Can mean, median, or mode be calculated from all statistical data? Explain why or why not. When is the meanthe best measure of central tendency? When is the median the best measure of central tendency?****Describe a business situation, other than what has already been selected by fellow students or selected from the team assignment, where mean and standard deviation can be used in decision making. Describe how calculation of mean and standard deviation can help in making a decision.****What level of data is a telephone number? Explain.****Does all data have a mean, median, or mode? Why or why not? When is the mean the best measure of central tendency? When is the median the best measure of central tendency?Why is the population shape a concern when estimating a mean? What effect does sample size, n, have on the estimate of the mean?****Week 3 Discussion Questions****What are the differences between probability and coincidence? Can the probability be more than 1 or less than 0? Explain why or why not.What is the role of probability concepts in business decision-making? Provide specific examples.What are the basic differences between a discrete and a continuous distribution?What are the characteristics of standard normal distribution? Explain how to calculate the z-test static. Explain how a z-value is used to calculate the area under the distribution and the meaning of P(0 to z) when z = 1.96****Week 4 Discussion Questions****What are some terms related to hypothesis testing with which you are already familiar? Why do null and alternative hypotheses have to be mutually exclusive?Why does the significance level differ among industries? Will the null hypothesis be more likely to be rejected at α = 0.01 than α = 0.10? As the significance level increases to α = 0.10 from α = 0.01, which type error is more likely to occur? What can be done to reduce the likelihood of incurring this error?****Please explain the five steps used in hypothesis testing. How does the five-step procedure for hypothesis testing differ when comparing two groups using a***t-*or*z-*test? How is the process similar?Please explain terms related to hypothesis testing; please explain null and alternate hypotheses, explain the difference between two different test statistics, then define the equations used in both. Why do null and alternative hypotheses have to be mutually exclusive?
