Assignment 1 A1.1: Chapter 2, Problem 2.1, Check the Completed Questionnaires. A1.1.a. Process First, count the questionnaires and arrange them in order of the ID number. Second, go through the questionnaires one by one in order and check the answers for its completeness and clarity, for example, check the wrong value, ambiguous answer, or blank answer. Third, come up with rules of how to handle the problem data. The important thing is that the rules should be consistently applied to handling of all the data from the questionnaires to avoid the bias in research results (Morgan et al., 2013). A1.1.b. Findings There are altogether twelve questionaries with the numbered ID on top of it. They are filled in manually by the participants. According to the numerical order of ID, all the answers in the questionaries #1 to #6 are readable and complete, which are readily to be entered under the guidelines for data coding. Different kinds of problem data are identified in the the questionaries 7 to 12. For questionaries #11 and #12, the answers for question 1 are not been clearly marked. Both 3 and 4 are circled in #11. A cross is marked in the space between 2 and 3. In this two cases, an average value of the two numbers would be used. The final answer for question 2 in #11 would be 3.5, and 2.5 to #12. For questionaries #8 and #11, the answers for question 2 have errors. Two name of the college are marked in #8 rather than a single answer. This answer is regarded as others, which is different from the three listed answers. A new legitimate value “4=others” would be developed. A written answer of “biology” is given in #11 with no marking of any of the existing answers. In this case, it is logical and reasonable to list the biology in the field of science. The final answer for question 3 in #11 would be Art and science. For questionaries #7, #9, #11 and #12, the answers for question 5 is not exact. A logical reasoning of the GPA could be any round numbers or numbers with two digit after decimal rang from 0-4 would be applied in interpreting these answers. The GPA 250 in #7 is regarded as 2.50 with a missing decimal. The GPA “about 3 pt” in #7 is regarded as 3. The GPA 9.67 in #11 is regarded as invalid answer since it is out of the GPA range.
