资料:For the development of Crunchy Nut (a product),K company has used various methods of primary data collection. Primary market data may involve qualitative research or quantitative research. Qualitative data is connected more about opinions, feelings and attitudes. Quantitative data is in numerical form and is usually gathered from a large sample of respondents.Qualitative research establishes a conversation with consumers. It prompts consumer reaction to, for example, a new product idea and helps researchers understand what they think of it, how it makes them feel, why they find it interesting or not.Qualitative research may be obtained through focus groups, where a moderator captures feedback from a group of six or seven consumers to the ideas shown to them. Those ideas may take the format of drawings or having new food prototypes to taste. Quantitative research may use questionnaires administered to large numbers of respondents. This allows statistical analysis. It may involve the use of scales, so numbers get associated with a particular meaning-for example, on an evaluation scale of 1 to 7, where 1 means very poor and 7 means excellent. Crucially those numbers need to be interpreted to enable the business to understand the consumers' overall response.What is the passage about?A.The development of Crunchy Nut.B.K Company's production line.C.Qualitative data collection.D.Two approaches to data collection.

共用题干第三篇Animal Testing ControversyTo paraphrase 18th-century statesman Edmund Burke,"All that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research.Scientists need to respond forcefully to animal rights advocates,whose arguments are confusing the public and thereby threatening advances in health knowledge and care.Leaders of the animal rights movement target biomedical research because it depends on public funding,and few people understand the process of health care research.Hearing allegations of cruelty to animals in research settings,many are perplexed that anyone would deliberately harm an animal.For example,a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is animals一no meat,no fur,no medicines.Asked if she opposed immunizations,she wanted to know if vaccines come from animal research.When assured that they do,she replied,"Then I would have to say yes."Asked what will happen when epidemics return,she said,"Don't worry,scientists will find some way of using computers."Such well-meaning people just don't understand.Scientists must communicate their message to the public in a compassionate,understandable way一in human terms,not in the language of molecular biology.We need to make clear the connection between animal research and a grandmother's hip replacement,a father's bypass operation,a baby's vaccinations,and even a pet's shots.To those who are unaware that animal research was nee-- ded to produce these treatments,as well as new treatments and vaccines,animal research seems wasteful at best and cruel at worst.Much can be done.Scientists could"adopt"middle school classes and present their own re-search.They should be quick to respond to letters to the editor,lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth.Research institutions could be opened to tours,to show that laboratory animals receive humane care.Finally,because the ultimate stakeholders are patients,the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper,who has made courageous statements about the value of animal research,but all who receive medical treatment.If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.The author believes that,in face of the challenge from animal rights advocates,scientists should________.A:communicate more with the publicB:employ hi-tech means in researchC:feel no shame for their causeD:strive to develop new cures
