2. Writing a Hypothesis (Obj. 2)Write a positive hypothesis and then restate it as a null hypothesis for each of the following research topics. Hypotheses for topic (a) are given as an example. a. A study to determine functional business areas from which chief executive officers advanced in their organizations. Functional areas include legal, accounting, marketing, etc. Positive Hypothesis: Chief executives advanced primarily through the legal background area. Null Hypothesis: No relationship exists between chief executives’ advancement and their functional field backgrounds. b. A study to determine whether listening to music using mp3 player ear buds contributes to hearing loss. c. A study to determine whether a person’s career success is related to mentoring experiences. d. A study to determine the relationship between college -students’ gender and their final grades in the business communication course. Project the Solution slide and discuss the answers in class, or assign the Student Handout (at the end of this guide and online) as homework. a.
Null Hypothesis: No relationship exists between chief executives’ advancement and functional field backgrounds. Note: In a hypothesis, the word significant usually is added when tests of significance are to be used. Of course, variations are easily possible. b.
Null Hypothesis: No relationship will exist between the use of ear buds and hearing loss. c.
Null Hypothesis: No relationship will exist between the occurrence of mentoring experiences and a person’s career success. d.
Null Hypothesis: No correlation exists between students’ genders and their final business communication course grade. 3 Limiting the Scope of the Problem (Obj. 2)What factors might limit or influence your findings in any of the studies in Activity 2? Could you apply the findings of the Activity 2 studies to a broader population than those included in the studies? Why or why not? Studies may be limited by sampling selection and size and by methods used to gather data. In experimental studies, limitations might include time of day, different teaching abilities, student differences, and a variety of other factors. Students should recognize that limitations do exist and that to generalize findings beyond the sample requires meticulous research methodology. 4 Selecting a Research Method (Obj. 3)What research methods would you use for each of the research problems identified in Activity 2? Research methods used in addition to library research:
5 Outlining a Search Strategy (Obj. 3)Outline a secondary search strategy for one of the topics in Activity 2. What printed indexes would you use? What electronic search techniques would you use? Answers will vary, but should include strategies for using both published and electronic sources. 6 Using Sampling Techniques (Obj. 4)You are to conduct a survey of residents’ attitudes toward recycling in a town of 35,000 people. Describe how you might construct a sampling procedure to avoid having to survey the entire population. A sample could come from a telephone list, tax assessor’s files, or other numeric sources at random. Perhaps 10 percent might have to be included. 7 Collecting and Documenting Secondary Data (Obj. 4)Select one of the research problems in Activity 2. Locate four related articles using both printed and electronic sources. As directed by your instructor, prepare a Reference page using APA style or another style specified by your instructor. (See Style cards bound in the back of the textbook.) Refer to guidelines and sample citations in the Style cards in evaluation. Reinforce to students that some elements may not be present in a given electronic citation. 8 Developing Questionnaire Items (Obj. 4)In teams of three or four, develop a customer satisfaction questionnaire for a restaurant of your choice. Participants might be asked to rate on a 4-point scale the speed of service, friendliness of staff, cleanliness of the facility and restrooms, and quality of the food. 9 Computing Measures of Central Tendency and Preparing a Table (Obj. 4)Refer to your companion website for information about measures of central tendency. The following figures represent the value of stock options in thousands of dollars issued to executive management of 25 local high-tech firms. Access a downloadable version of this activity at your companion website. a. Compute the range, mean, median, and mode of the following distribution. 50 91 164 217 425 60 130 170 260 596 65 139 170 283 600 70 143 170 350 650 78 159 204 390 690 b. Tally the scores in Part a in seven classes beginning with 0-99, 100-199, and so on to 600-699. When you have tallied the scores, compute the mean, median, and mode for each class. c. Prepare a table for the data and indicate the appropriate percentages for each class. Write a sentence to introduce the table in a report.
a. See solution slide. In computing values, add 000s to answers; that is, multiply answers by 1,000. b. See solution slide.
c. An appropriate table for the data may look similar to the one shown on the solution slide. Introductory sentence: Figure 1 shows the mode and the median, both at 170, are the best measures of central tendency for this set of data because the mean is skewed by the three numbers over 600.
