One of the marketing research industry's big problems is the decline in participation in surveys. Which one of the following errors is associated with this problem? a) Non-response error. Ob) Sampling error. c) Item omissions. d) Non-probability error. e) Falsehoods on the part of respondents. Before starting the data analysis Jim has to determine the level of measurement of the variables. What should Jim conclude about the level of measurement of the above questions? a) Q2 & Q3 are non-metric, but there is not enough information to determine the level for Q1 because it is an open-ended question. b) Q1 is a metric variable, and Q2 & Q3 are non-metric variables. O c) All of the questions non-metric variables. d) Q1 is a non-metric and Q2 & Q3 are metric variables. e) All of the questions are metric variables, In order to be potentially useful for a marketing manager, differences must at minimum be: a) Any difference should be important to a manager. b) New and not part of existing knowledge. c) Statistically significant. d) At a ratio of 10 to 1. e) At a ratio of 2 to 1. Indigo wants to conduct a survey among all members of their book club I Rewards. They plan a probability sample. Which of the following is the most correct method of determining sample size? a) Use the 'percentage of population approach'. b) Because the longer you collect data, the more respondents you get, use the 'all that time will permit approach'. c) Calculate sample size using the confidence interval approach. d) Because they have both Canadian and foreign members, use the 'equal representation approach, such as 500 from each sub-population. e) Because a bigger sample is better, use the 'all that can be afforded approach. The researcher for the Kitsilano Burger Bar customer survey was analyzing the Sample Profile. He found that the gender split was exactly 50-50 and that 20 percent earn over $50,000 per year. Comparing these figures to Stats Canada data for the Kitsilano area would be a way of validating the sample. a) True b) False A pie chart is useful for comparing a specific part to the whole. However, it should be limited to relatively few categories. a) True b) False Question 24 (1 point) You have learned about testing between groups and that there are different tests for Metric and Non-Metric variables. To test the difference between two Non-Metric Variables the appropriate test is to compare averages. a) True b) False Richmond Security, a commercial and residential alarm and security company, conducted a probability survey among its current customers to determine their likelihood of purchasing a new alarm system. The survey showed that 35% of the respondents indicate they are Likelyor Very Likely to purchase such a system. The margin of error is +5%. Which of the statements below are correct? a) The real percentage of the customers who are likely to purchase the new alarm system ranges between 30%-40%. Ob) The real percentage of the customers who are likely to purchase the new system ranges between 0%-5%. c) There is a 95% chance that Richmond Security will make the right decision on this data. d) There is + or -5% chance that Richmond Security will make the right decision. e) There is a 5% chance that Richmond Security will make the wrong decision on this data If respondents differ a lot in their answers, you would expect that: a) There is an average standard deviation. b) There is a low standard deviation. c) The Frequency distribution is very narrow and the data points are close together. d) There is a high standard deviation. e) There is low variance. The lead researcher for Amazon is planning a sample to survey the members of Amazon Prime. To be able to draw the sample, a master list of all the sample units in the population must be defined. This list is known as the: a) Master frame. Ob) Sample list. c) Population frame. d) Sample frame. e) Population master list. Significant findings and recommendations from research are meaningless unless you can: a) Provide supporting documentation in your report's appendix. Ob) Communicate in a way that is meaningful to your client. c) Provide a detailed bibliography. d) Include all the statistical runs made for the project. e) Write them in a physically attractive final report
