the differences between pre-coded and open-ended quétin

Welcome to our presentation Members of our group • Dang Thi Phuong • Hoang Thi Mui • Ma Thi Hanh • Pham thi Ngoc Yen • Tran Thi No Question14 • What is the difference between pre-coded and open-ended questions? • What are the principles of coding them? The differences between pre-coded and open-coded questions Open-ended questions Pre-coded or closed questions • The interviewer asks a questions without any prompting of the range of answers to be expected, and writes down the respondent ‘s reply word for word  Eg: Asking the respondents to state any five aspects of the job that they find very interesting and challenging in jobs The respondent is offered a range of answers , or option , to choose from  Eg: The researchers might list 10 or 15 aspects that might seem interesting or challenging in jobs and ask the respondents to rank the first five among these in order of their preference. . • Require “probes”from the interviewer to elaborate or continue the discussion. •Provide the reseacher with a rich array of information. •Enable respondent to give their general reactions to the questions. • Help the respondent to make quick decisions to choose among several alternatives before them. •Often provide cruder and less subtle information. •Have loss of spontaneity and expressiveness. • The problem of open- ended questions is interview bias. •The coding and data- entry process is greatly simplified. • Because the option of expounding on the topic isn’t given to a respondent, there is no bias toward the articulate. • The coding and data- entry process is complex. The principles of coding questions • Coding involves converting questionaire answers to numbers • The coding process is straighforward , with each question being given a column and each answer a single numeric code in the table. • Pre coded or closed questions.– Eg: what sort of trip do you use the bus for? a.Going to work b.Going to school /college /university c.Shopping d.Visiting friends/ relatives e.Leisure f.Other personal business( e.g. visites the doctor) For this example a column is reserved for each answer category because one respondent can give than one answer. In all other questions only one answer is possible, so only one column is allocated. ( examples in the table 7.1) • Open- ended questions One approach is simply to write down all the answers as they are given by the respondents. It would propably be useful to group the answer in some ways Eg: Answers which are very opposed to the closure of the bus services would be group together, while those that expressed concerns about ,say ,safety might be put together in another group. [...]...• Second approach is to group the answers and give them a code Eg : what is your opinion on the proposed withdrawal of the No.66 bus service?  Response •Very opposed to removal of bus service •Moderately opposed to removal of bus service •Not concerned/ in favour Code Code .
