3. (A) Data types
There are two main types of survey data:

7. Mini Exercise
Underline the quantitative and circle the qualitative information from the following description:
ADMC students are cooperative and group oriented. They enjoy working in teams to get work accomplished. Seventy five percent reported that they would rather study as part of group than alone. In addition, eighty percent reported that they share their work with friends.

8. Survey design
Surveys are common way to collect information from people
When designing a survey the researcher must decide:
whether they are going to employ an oral, written or electronic method
whether they are going to choose questions which are open (qualitative) or closed-ended (quantitative)

9. Surveys Most surveys are quantitative and have closed ended items
The respondent chooses from a closed set of answers
The response choices are calculated across respondents into percentages or averages
When the respondent can give any answer to the item it is open ended.
The researcher looks at the answer and considers its meaning
The researcher may apply a category or theme to the response

10. Closed ended questions
The respondent must choose from closed set of responses
Yes/No
True/False
Multiple choice
Ranking Scale
Likert scale question

11. Closed questionnaire item sample 1
Yes / No question
________________________________________
Do you think lack of sleep can affect your academic performance?
Yes / No
_______________________________________

12. Closed questionnaire item sample 2
True / False question
_______________________________________
Lack of sleep has affected my academic performance
True / False

13. Closed questionnaire item sample 3
Multiple choice question
________________________________________
Which of the following has most affected your academic performance in the last year?
A. Over eating
B. Lack of sleep
C. Technology problems
D. Transportation issues
E. Other
______________________________________________

14. Closed questionnaire item sample 5 Likert scale
Typical five-level Likert item:
People who regularly drive at speeds far in excess of the speed limit should loose their driving licenses.
Strongly disagree
Disagree
Neither agree nor disagree
Agree
Strongly agree Or
Strongly Disagree Strongly Agree

15. Closed questionnaire item sample 6 Likert scale
Level of satisfaction – 5 point
I am satisfied with the service I received
Not at all satisfied
Slightly satisfied
Moderately satisfied
Very satisfied
Extremely satisfied Or
Not at all satisfied Extremely Satisfied

16. The advantages of closed questionnaires
are more cost and time effective than interviews when sample sizes are large.
are easier to analyze. The information is usually presented in averages and percentages.
are more familiar to most people. Nearly everyone has had some experience completing questionnaires and they generally do not make people apprehensive.
reduce bias. The researcher's own opinions will not influence the respondent to answer questions in a certain manner. There are no verbal or visual clues to influence the respondent.

17. Qualitative research Open ended answers (thematic analysis)
Compared to closed ended items open ended answers can provide greater detail . Also information can arise which is important but which the researcher never thought to put in the questionnaire. For example:
One thing I like about ADMC is students can go into the faculty area and talk to their teachers. In the previous college I attended students had to make appointments. For me this was really inconvenient. I like it a lot better when we can see the teacher when I have time.

18. Qualitative research Interviews and focus groups
Semi-structured interview
The interviewer follows a list of questions which are prearranged. The interviewer may also ask other questions allowing new ideas to be brought up during the interview as a result of what the interviewee says.
Unstructured interview
The interviewer does not follow a pre-arranged set of questions. There may be a few key questions set in advance but the discussion is allowed to proceed like a friendly, non-threatening conversation.
Focus group
A group of people are brought together to discuss their perceptions, beliefs, opinions and attitudes on a topic of interest.
When analysing qualitative research, the researcher tries to reach new understandings and insights. This is can be done by categorizing comments into themes and topics.

19. Research terms – Data presentation
The population of the study is all the people your study is about. For example, ADMC students.
Demographic information is background on the population. It includes factors such as age, gender, nationality, occupation, and religion.
The N is the number of people who participated in the study or the size of the sample (N=50). It is also used to show how many people chose a answer on a questionnaire.
The M is the mean result for a Likert scale questionnaire item (M = sum / N)

20. Research terms – Sampling
The sample are the people which you directly collected information from.
An accidental sample is where information comes from people who happen to be available. For example you go to the cafeteria and hand out questionnaires.
A random sample is where a technique is used so that every member of the population has an equal chance of participating in the study. For example, every fifth student on the student list is sent a questionnaire.
Stratified sampling is where subgroups are sampled independently. For example, when the researcher is interested in the opinions of female students compared to male students he might sample the female students at ADMC separately due to their small numbers compared to the male students.

21. Research terms Consent and confidentiality
This is a promise or a guarantee from the researcher to keep all information secret unless permission is given by the respondent. The researcher may discuss the information provided. However, the researcher must ensure that no other person will be able to link the information to the respondent.
Anonymity
This is when the identity of the respondent is unknown even to the person(s) analyzing the data.
In social research it is good practice to obtain consent and to guarantee confidentiality or anonymity prior to collecting data from a respondent.

22. Research terms - truth and reliability
Validity is the truth value of research.
Failing students indicated on a questionnaire that the reason for failing is because teacher do not provide clear instructions. The researcher concludes poor instruction is the main reason for students failing. Later the researcher finds students who fail tend to have low IELTS scores. The real reason for failing may be because of problems with English rather than teaching approaches.
Reliability is the likeliness that the same or similar results would occur if the instrument was used more than once. Random samples provide better reliability than accidental samples.
The student goes to the cafeteria in the morning and surveys the students there. Most students indicate that they do not smoke. The next day he goes to the cafeteria in the evening. Most students indicate on the questionnaire that they do smoke. The reliability of the results are in question.
Response bias is the tendency for a respondent to give the same answer to almost every item on the survey. Alternatively it may be when the respondent tries to give an answer he thinks the research wants rather one that is true.
The questionnaire item reads : T / F – I am a bad driver. Nobody answers true.

23. Review Questions
Most surveys are quantitative and have closed ended items:
The respondent chooses from a __________ set of answers
The response choices are calculated across respondents into percentages or __________

Are easier to _____________. The information is usually presented in averages and percentages.
Are more ______________ to most people. Nearly everyone has had some experience completing questionnaires and they generally do not make people apprehensive.
Reduce ___________. The researcher's own opinions will not influence the respondent to answer questions in a certain manner. There are no verbal or visual clues to influence the respondent.

24. Review Questions Research strength concepts Statistical concepts
Validity is the ___________ value of research.
Reliability is the likeliness that the _________ or __________ results would occur if the instrument was used more than once. Random samples provide better reliability than accidental samples.
Response bias is the tendency for a respondent to give the same answer to almost every item on the survey. Alternatively it may be when the respondent tries to give an answer he thinks the researcher _________ rather one that is true.
Statistical concepts
The___________________ of the study is all the people your study is about. For example, ADMC students.
The _____________ is the number of people who participated in the study or who the size of the sample. It is also used to refer to the number of people chose an answer on a questionnaire.
The ____________ is the mean result for a Likert scale questionnaire item (M = sum / N)
The ____________ are the people which you directly collected information from.

25. Review Questions
When the respondent can give any answer to the item it is open ended:
The researcher looks at the answer and considers its meaning
The researcher may apply a category or _________ to the response
This interview type would be used when the researcher wants to receive answers following a set of questions. However, the researcher may also wants to able to ask for clarification of answers and follow-up questions _____________________
This approach may be used when the researcher want to a range of points of view on a topic but does not have time to conduct a lot of interviews _____________________
___________________ is the promise from the researcher to keep information private unless permission is given by the respondent.
