Q

Control group

A

in experimentation, a group of subjects to whom no experimental stimulus is administered and who should resemble the experimental group in all other respects. A comparison of the control group and experimental group at the end of the experiment points to the effect of the experimental stimulus

Q

bias

A

that quality of a measurement device that tends to result in a misrepresentation of what is being measured in a particular direction. For example, the questionnaire item ‘‘Don’t you agree that the president is doing a good job?’’ would be biased in that it would generally encourage more favorable responses.

Q

contingency question

A

a survey question intended for only some respondents, determined by their responses to some other question. For example, all respondents might be asked whether they belong to the cosa nostra, and only those who said yes would be asked how often they go to company meetings and picnics. The latter would be a contingency question.

51
Q

why would a double blind experiment be used.

A

to reduce experimenter bias.

52
Q

how representative of a sample is probability sampling.

A

the degree of resemblance ( representativeness) achieved by probability sampling is largely a function of the sample size. As a general guideline, probability samples of less than 100 are not deemed to be terribly representative, and social science experiments seldom involve that many subjects in either experimental or control groups.

53
Q

is probability sampling used to select subjects from a larger population?

A

no it is seldom used for this. However the logic of random selection is used when researchers assign subjects to groups.

54
Q

what are the two arguments in favor of randomization over matching

A
  1. you may not be in a position to know in advance which variables will be relevant for the matching process. 2. Most of the statistics used to analyze the results of experiments assume randomization.
55
Q

When does randomization or matching make better sense.

A

randomization only makes sense if you have a fairly large pool of subjects. This is so that the laws of probability sampling apply.

56
Q

when does matching make sense

A

when you have a limited number of subjects.

57
Q

can researchers mix matching and randomization.

A

yes sometimes they can be combined.

58
Q

what is the one shot case study

A

the researcher measures a single group of subjects on a dependent variable following the administration of some experimental stimulus.

59
Q

what is an example of a one shot case study.

A

showing a Muslim history film to a group of people and then administer a questionnaire that seems to measure prejudice against Muslims.

60
Q

What is the flaw of the one shot case study.

A

it lacks a pretest so we can’t be sure if the experimental stimulus caused the change in the respondents attitude.

61
Q

one group pre-test post- test design

A

this adds a pretest for the experimental group but lacks a control group.

62
Q

what is the flaw of the one group pre-test post- test design?

A

it suffers from the possibility that some factor other than the independent variable might cause a change between the pretest and post- test results.

63
Q

how does the flaw of the one group pre- test post- test relate to the Muslim video example?

A

a Muslim leader may have been Assassinated but we cant be sure that the film is what caused the reduction in prejudice.

64
Q

what is the static group comparison

A

is based on experimental and control groups but has no pre- tests.

65
Q

what is the static group comparison in the muslim video.

A

we might show the muslim history film to one group and not to another and then measure prejudice in both groups.

66
Q

how is the static group comparison flawed in this example.

A

If the experimental group had less prejudice at the end of the experiment, we might believe the film was responsible. However unless we had randomized our subjects we would not know whether the two groups had the same degree of prejudice to start with.

67
Q

what is the one shot case study deemed good for.

A

it represents a common form of logical reasoning in everyday life.

68
Q

what is the threat of history?

A

During the course of the experiment historical events may occur that confound the experimental results.

69
Q

what is the threat of maturation.

A

People are continually growing and changing, and such changes can affect the results of the experiment.

70
Q

what is the threat of testing

A

often the process of testing and retesting influences people’s behavior, thereby confounding the experimental results.

71
Q

what is the threat of instrumentation

A

IF we use different measures of the dependent variable in the pretest and post-test how can we sure they are comparable to each other.

72
Q

statistical regression

A

sometimes its appropriate to conduct experiments on subjects who start out with extreme scores on the dependent variable. There is a danger, then, that changes occurring by virtue of subject’s starting out in extreme positions will be attributed erroneously to the effects of the experimental stimulus.

73
Q

selection biases

A

Comparisons don’t have any meaning unless the groups are comparable at the start of an experiment.

74
Q

experimental mortality

A

often experimental subjects will drop out of the experiment before it has been completed, and this can affect statistical comparisons and conclusions.

75
Q

causal time order

A

ambiguity about the time order of the experimental stimulus and the dependent variable can arise. Whenever this occurs, the research
conclusion that the stimulus caused the dependent variable can be challenged with the explanation that the ‘’ dependent’’ variable actually caused changes in the stimulus.

76
Q

diffusion or imitation of treatments

A

when experimental and control group subjects can communicate with each other, experimental subjects may pass on some elements of the experimental stimulus to the control group.

77
Q

compensation

A

subjects in the control group are often deprived of something considered to be of value. In such cases, there may be pressures to offer some kind of compensation. In such a situation the control group is no longer a genuine control group.

78
Q

compensatory rivalry

A

in real life experiments the subjects deprived of the experimental stimulus may try to compensate for the missing stimulus by working harder.

79
Q

demoralization

A

on the other hand, feelings of deprivation within the control group may result in their giving up. In educational experiments, demoralized control- group subjects may stop studying, act up, or get angry.

80
Q

strengths of the experimental method

A

the chief advantage of a controlled experiment lies in the isolation of the experimental variables impact over time. further because individual experiments are often rather limited in scope, requiring relatively little time and money and relatively few subjects we often can replicate a given experiment several times using several different groups of subjects. Also as in all other forms of scientific research, replication of research findings strengthens our confidence in the validity and generalizability of those findings. they lend themselves to a logical rigor that is often much more difficult to achieve in other modes of observation.
Experiments are especially well-suited for research projects involving
limited concepts, well-defined concepts, and hypothesis testing.

81
Q

weaknesses of the experimental method.

A

the greatest weakness lies in their artificiality. Social processes that occur in a laboratory setting might not necessarily occur in natural social settings.

82
Q

when is it appropriate to use open ended questions

A

in depth qualitative interviewing relies almost exclusively on open ended questions. Also used in survey research. When you want more detailed answers on a topic that can’t be answered by closed ended questions.

83
Q

when is it appropriate to use closed ended questions.

A

are very popular in survey research because they provide a greater uniformity of responses and are more easily processed than open ended ones.

84
Q

what to avoid when asking survey questions

A
Select appropriate question forms. 
„

„
Avoid biased items and terms.
85
Q

what is the general questionnaire format

A

Uncluttered, one question per line, consistent format

86
Q

why is it important to pretest a questionnaire.

A

to protect against errors such as an ambiguous question, one that people cannot answer, or some other violation of the rules.

87
Q

what are the difficulties with mail questionnaires

A

people are busy and may not want to take the time to mail them out. people may avoid them. it takes a long time to send them all out, and input the data. People may see it as junk mail.

88
Q

how can problems with mail questionnaries be adressed.

A

using a self mailing questionnaire which requires no return envelope. By listing the return address and postage. Pay for the postage so all they have to do is put it in their mailbox.

89
Q

what are the advantages of survey interviews over questionnaires?

A

the presence of an interviewer also generally decreases the number of ‘‘don’t knows’’ and ‘‘no answers’’. Higher response rates. People are more reluctant to turn down a person than a questionnaire. If a person doesn’t understand a question clearly the interviewer can clarify. Can observe respondents as well as ask questions.

90
Q

what are the five general rules for successful interviewing.

A
  1. dress appropriately. 2. be familiar with questionnare. 3.follow question wording exactly. 4. record responses exactly. 5. probe when necessary.
91
Q

what are the advantages and disadvantages of telephone surveys.

A

limited to people who have telephones. in 2003 95.5 percent of people had telephones. if done from a telephone book would not include those who had their numbers omitted. cheaper and more time efficient. people will most likely not answer if they don’t recognize the number.

93
Q

how do random digit dialing and computer assisted telephone interviewing overcome some of the weaknesses of the telephone survey.

A

random digit dialing can help randomly select numbers efficiently that might not be listed in the phonebook.

94
Q

how do random digit dialing and computer assisted telephone interviewing overcome some of the weaknesses of the telephone survey.

A

random digit dialing can help randomly select numbers efficiently that might not be listed in the phone book. computer assisted telephone interviewing automatically prepares the data for analysis.in Computer assisted telephone interviewing the researcher can begin analyzing the data before the interviewing is complete. This helps gain an advanced view of how the analysis will turn out. Is also cost effective cuts out the labor of hiring human beings.

95
Q

What are the strengths and weaknesses of self administered questionnaires.

A

Cheap and fast. More willingness to answer controversial items.

96
Q

what are the strengths and weaknesses of interview surveys.

A

fewer incomplete questionnaires. More effective for complicated questionnaires. Possible response biases.

97
Q

What are the strengths and weaknesses of telephone surveys

A

cheaper and more time efficent. not everyone has a phone. cell phones not included.

98
Q

online surveys

A

available software and websites.

99
Q

qualitative field research compared with surveys and experiments.

A

it can give a comprehensive perspective to research. by going directly to the social phenomenon under study and observing it as completely as possible, researchers can develop a deeper and fuller understanding of it. as such, this mode of observation is especially, though not exclusively, appropriate to resarch topics and social studies that appear to defy simple quantification. Also may recognize several nuances of attitude and behavior that might escape researchers using other methods. Is especially appropriate for the study of those attitudes and behaviors best understood within their natural setting as opposed to somewhat artifical settings of experiments and surveys. Field research is well suited for the study of social processes over time.

100
Q

types of research topics appropriate for field research.

A
  1. practices: various kinds of behavior, such as talking or reading a book. 2. episodes: a variety of events such as divorce, crime, and illness. 3. encounters: two or more people meeting and interacting. 4. Roles and social types: the analysis of the positions people occupy and the behavior associated with those positions: occupations, family roles, ethnic groups. 5. Social and personal relationships: behavior appropriate to pairs or sets of roles: mother-son relationships, friendships, and the like. 6. groups and cliques: small groups, such as friendship cliques, athletic teams, and work groups. 7. organizations: formal organizations, such as hospitals or schools. 8. Settlements and habits: small scale ‘‘societies’’ such as villages, ghettos, and neighborhoods, as opposed to large societies such as nations which are difficult to study. 9. Social worlds: ambiguous social entities with vague boundaries and populations, such as ‘‘the sports world’’ and ‘‘wall street’’. 10. subcultures and lifestyles: how large numbers of people adjust to life in groups such as a ‘‘ruling class’’ or an ‘‘urban underclass’’.
101
Q

five advantages of focus groups.

A
  1. the technique is a socially oriented research method capturing real life data in a social environment. 2. it has flexibility 3. it has high face validity. 4.it has speedy results 5. it is low in cost
112
Q

ethical issues involved in qualitative field research

A
  1. is it ethical to talk to people when they do not know you will be recording their words? 2. is it ethical to get information for your own purposes from people you hate? 3. is it ethical to see a severe need for help and not respond to it directly. 4. is it ethical to be in a setting or situation but not commit yourself wholeheartedly to it? 5. is it ethical to develop a calculated stance toward other humans, that is, to be strategic in your relations? 6. Is it ethical to take sides or to avoid taking sides in a factionalized situation? 7. is it ethical to ‘‘pay’’ people with trade-offs for access to their lives and minds? 8. Is it ethical to ‘‘use’’ people as allies or informants in order to gain entree to other people or to elusive understandings?
113
Q

strengths of qualitative field research.

A

especially effective for studying subtle nuances in attitudes and behaviors and for examining social processes over time. Chief strength lies in the depth of understanding it permits. Flexibility. Can be relatively inexpensive.

114
Q

weaknesses of qualitative field research

A

being qualitative rather than quantitative, it’s not an appropriate means for arriving at statistical descriptions of a large population.

115

Q

how reliability and validity relate to qualitative field research

A

validity- greater than survey and experimental measurements. field researchers commonly give detailed illustrations. reliability- potential problems with reliability. Even though they are very in depth measurements are often very personal. be wary of purely descriptive measurements.

118
Q

topics appropriate for field research

A

topics that defy simple quantification. Attitudes and behaviors best understood in their natural setting. Social processes that occur over time.

119
Q

topics appropriate for field research

A

practices ( behaviors). Episodes ( events). Encounters. social and personal relationships. Groups and cliques. Organizations. roles and social types. Subcultures and lifestyles.

120
Q

how should you record observations in qualitative field research.

A

take detailed notes but balance with observations. rewrite notes with observations soon after observations with filled in details. record everything.

121
Q

why is it important to specify and measure interventions in evaluation research.

A

combining complementary measures with proper control- group designs should allow you to pinpoint the effects of the program you’re evaluating. so you can specify the control and experimental group. So you can define the population for whom it is appropriate.

122
Q

what are experimental contexts

A

those aspects of the context of an experiment researchers think might affect the experiment.

123
Q

advice for operationalizing sucess or failure of an operation

A

ultimately, the criteria of success and failure are often a matter of agreement. make sure the research design measures the specified outcome. researchers must take measurement seriously in evaluation research, carefully determining all the variables to be measured and getting appropriate measures for each.

124
Q

why is evaluation research particularly subject to logistical problems.

A

they grow out of the fact that it occurs within the context of real life. takes place within frequently uncontrollable daily life. Lack of control can create real dilemmas for the researcher.

125
Q

social intervention

A

researchers use social indicators to monitor aspects of social life. finding out whether death penalty lowers the murder rate.

126
Q

definition of qualitative field research

A

research that more typically yields qualitative data: observations not easily reduced to numbers.although there can be quantitative it is typically qualitative.

127
Q

topics appropriate for evaluation research.

A

needs assessment studies, cost benefit studies, monitoring studies, and program evaluations/ outcome assessments. Is sometimes coupled with the intentions of participatory action research.
