...ANSWERS TO CASES Chapter 1 DiGiorno Pizza: Introducing a Frozen Pizza to Compete with Carry-Out In conducting research for the launching of a new product it is imperative that the target population be identified. In this case, who are the people most likely to be interested in purchasing and consuming frozen pizzas in lieu of carry-out pizzas? How are these people to be identified for sampling (Chapter 7 refers to this group as the “frame”)? Should a test market city or area be used? Why or why not? What mode of survey such as telephone, mail, or personal interview should be used? When should these people be surveyed? Does time of day, day of the week, or season of the year make any difference? What types of measurements should be taken? Some possible measurements might include dollar amounts spent per week of pizza per family, number of pizzas purchased per month, percentage of family pizza consumption that is frozen pizza, and total amount spent per month on take out food. 1. One population that was identified was “pizza lovers”. These people may have been previously identified by market researchers based on number of pizzas purchased per month, use of coupons, or from previous surveys. Another population mentioned in the case was women ages 25 to 54.

...THE EFFECT OF STUDY HABITS ON THE ACADEMIC PERFORMANCE OF FRESHMEN EDUCATION STUDENTS IN XAVIER UNIVERSITY, CAGAYAN DE ORO CITY, SCHOOL YEAR 2008-2009” Chapter 1 THE PROBLEM A. Introduction The extent of student’s learning in academics may be determined by the grades a student earns for a period of learning has been done. It is believed that a grade is a primary indicator of such learning. If a learner earns high grades it is concluded that they may also have learned a lot while low grades indicate lesser learning. However, many experiences and studies found out that there are also several factors that would account for the grades. No single factor can be definitely pointed out as predicting grades. It has been an interplay of so many factors – gender, IQ, study habits, age, year level, parent’s educational attainment, social status, number of siblings, birth order, etc. In fact, almost all of existing environmental and personal factors are a variable of academic performance. However, at this point in time, the researchers would like to investigate the possible relationship of study habits and the factors affecting it to the academic achievement of under graduate education students of Xavier University- Ateneo de Cagayan. The investigation of on this area thus becomes a real and compelling motivation for the researchers to conduct this study. B. Conceptual Framework Independent variables as it influence the dependent variable...

...Chapter 10: Comparing Two Groups Bivariate Analysis: Methods for comparing two groups are special cases of bivariate statistical methods – Two variables exist: Response variable – outcome variable on which comparisons are made Explanatory variable – binary variable that specifies the groups Statistical methods analyze how the outcome on the response variable depends on or is explained by the value of the explanatory variable Independent Samples: Most comparisons of groups use independent samples from the groups, The observations in one sample are independent of those in the other sample Example: Randomized experiments that randomly allocate subjects to two treatments Example: An observational study that separates subjects into groups according to their value for an explanatory variable Dependent samples: Dependent samples result when the data are matched pairs – each subject in one sample is matched with a subject in the other sample Example: set of married couples, the men being in one sample and the women in the other. Example: Each subject is observed at two times, so the two samples have the same subject Categorical response variable: For a categorical response variable - Inferences compare groups in terms of their population proportions in a particular category - We can compare the groups by the difference in their population proportions: (p1 – p2) Example: Experiment: Subjects were 22,071 male physicians Every other day for five years, study participants...

...A Handbook on Thesis Writing 1 BASICS OF THESIS WRITING Thesis Writing is a requirement for graduating students particularly those who opted for Plan A (Thesis) instead of a comprehensive examination. This book focuses on the mechanics on how to develop a thesis and is made simple for easy understanding of the processes. Many students are confronted with tasks that demand good writing skills. They need guidance on how to go about the complex job of writing a thesis or dissertation. This book will therefore serve as a guide. Thesis Writing is subsumed under Technical Writing. All professional fields require technical documents that help readers perform tasks and understand specific tasks. As mentioned by some authors, thesis is classified under technical writing as it provides vital information to specific readers. Technical Writing refers to the provision of specific information to clearly identified readers who will use the information for a specific purpose. KEY FEATURES OF TECHNICAL WRITING Three Elements of Technical Writing. The elements are reader, purpose and writing situation. The reader seeks information for a specific purpose. The purpose is to design a document that will serve the reader's need and help the reader understand the information. The writing situation consist of both reader and purpose, as well as such factors such as the sponsoring organization's size, budget, ethics, deadlines, policies, competition and priorities.
