Q

25
Multichotomous question
respondents are asked to choose the alternative that most closely reflects their position on a subject
26
Response order bias
an error that occurs when the response to a question is influenced by the order in which the alternatives are presented
27
Split-ballot technique
A technique in which on phrasing is used for a question in half of the questionnaires while an alternate phrasing is used in the other half
28
Leading question
Do you believe that Sontai Airlines should stop airing its misleading advertisements?
29
Assumed consequences
When a question is not framed to clearly state the consequences and this generates different responses from individuals who assume different consequences
30
Double-barreled question
Asking one question after another
31
Funnel Approach
Start with broad questions, then get more specific towards end
32
Question order bias
tendency for earlier questions on a questionnaire to influence respondents' answers to later questions
33
Branching question
Ask questions based off of other questions or answers
34
Pretest
use of questionnaire on a trial basis in a small pilot study to determine how well the questionnaire works
35
Census
type of sample plan where data are collected from or about each member of a population
36
Sample
selection of a subset of elements from a larger group of objects
37
Population
all cases that meet designated specifications for a group
38
Incidence
percent of general population or group that qualifies for inclusion in the population
39
Parameter
- characteristic or measure of a population | - True value
40
Statistic
A characteristic or measure of a sample
41
Sampling error
difference between results obtained from sample and results that would have been obtained had info been gathered from population - decreased by increasing sample size - can be estimated - usually less troublesome than other kinds of errors
42
Sampling frame
List of population elements from which a sample will be drawn - customer database - telephone directories - lists developed by data compilers
43
Probability sample
has some chance to be selected
44
Non-probability sample
doesn't have a chance to be selected - convenience - judgement - quota
45
Sequential sample
sample formed on the basis of a series of successive decisions
46
Convenience sample
right place at the right time
47
Judgement sample
population elements are handpicked because they are expected to serve the research purpose -non-probability
48
Snowball sample
a judgement sample that relies on the researcher's ability to locate and initial set of respondents with the desired characteristics
49
Quota sample
certain important characteristics of the population are represented proportionately in the sample - non-probability - Better sense of overall geodemographic distribution (gender, income, etc.)
50
Simple random sample
each unit included in the population has a known and equal chance of being in the sample
51
Systematic sample
sample in which every x element in the population is selected for the sample pool after a random start
52
Sampling interval
k= Number in the sampling frame/Total sampling elements-k
53
Total sampling elements (TSE)
The number of population elements that must be drawn from the population and included in the initial sample pool in order to end up with the desired sample size
54
Stratified sample
Same within the group | Different between the groups
55
Cluster sample
Different within the group | Same between the groups
56
Precision
Degree of acceptable error in an estimate of a population parameter
57
Confidence
Degree to which the researcher can feel assured that an estimate approximates the true value
58
3 Factors researchers must take into account when selecting a sample size
Variance Precision Confidence
59
How to calculate a sample size when estimating means and proportions?
means n=z^2/H^2 (o^2) sample size = z-score/half-precision * (variance) proportions n= z-score / H^2 * estimated population proportion (1-estimated population proportion)
60
What way does the size of the population influence the size of the sample?
it doesn't | -variance is the only thing that may indirectly affect it.
61
What are non statistical methods of determining the sample size for a project?
- Secondary data - Other info - Depending on analysis type
62
Random error
error in measurement due to temporary aspects of the person or measurement situation and which affects the measurement in irregular ways. (mood, state of health, fatigue, situation in which measure is taken)
63
Physiological reaction
a measure of intensity but not necessarily level of favorability
64
Steps in questionnaire development.
1) specify what info 2) determine admin method 3) Determine content of individual questions 4) Determine form of response to each question 5) Determine form of response to each question 6) Determine question sequence 7) Determine physical characteristics of questionnaire 8) Develop recruiting message or script 9) Reexamine steps 1-8 and revise if necessary 10) pretest questionnaire and revise if necessary
65
Technique used by researchers to handle to get respondents to cooperate
- randomized response technique - Place sensitive questions near the end - Include a counter biasing statement - Ask about how others might feel - Ask for general rather than specific info
66
Wording issues
``` Simple words Avoid ambiguous words Avoid leading questions Avoid Unstated Alternatives Avoid assumed consequences ```
