what makes a survey a good survey?

Lösung anzeigen
TESTE DEIN WISSEN

Well-designed survey = properly implemented thus can generate necessary information of sufficient quality + accuracy with speed and at relatively low costs 


  • answers given describe accurately the characteristics of the person
  • sample is representative
  • collected information meets quality requirements established by survey objectives

what are ethical issues and requirements of a survey?

Lösung anzeigen
TESTE DEIN WISSEN
  • difficult to create a similar groups, which can funciton as a control group
  • informed consent: knowing consent of an individual/ legally authorized representative, without any element of force, fraud, deceit, duress, any other form of constraing/ coercion


requirements:

  • providing enough information about potential benefits + risks of harm to permit subjects to make informed decision + participation
  • assuring understanding of information
  • creating environment free from undue influence + coercion

TESTE DEIN WISSEN

what information should be given to the respondent before starting the survey?

Lösung anzeigen
TESTE DEIN WISSEN
  1. name of organization, interviewer name (if involved)
  2. sponsorship
  3. purpose of research
  4. statement about data confidentiality 
  5. assurance that participation is voluntary
  6. assurance that participans can skip any question they do not want to answer

TESTE DEIN WISSEN

shortly explain anonymity and confidentiality and why they are important

Lösung anzeigen
TESTE DEIN WISSEN

Anonymity = we do not know who participants are, panel design prevents it

Confidentiality = we know who participants are, but their identity will not be revealed in any way in resulting publication


concerns about anonymity + confidentiality influence respondents' willigness to participate

Lösung ausblenden
TESTE DEIN WISSEN

what can researchers do to ensure confidentiality?

Lösung anzeigen
TESTE DEIN WISSEN
  • training in confidentiality protection practices + data management
  • only use IDs to identify respondents
  • filled questionnaires stored in secure place, not accessible t non-project members
  • being careful when presenting data of (very) small samples/ categories of people which could be identified

TESTE DEIN WISSEN

what types of panel survey exist?

Lösung anzeigen
TESTE DEIN WISSEN

prospective/ hh panel

  • same cohort
  • collect data at least 2x

rotating panel

  • replace parts of the sample over time (rotate) with similar respondents from target population
  • reason: prevent respondent fatigue

retroperspective panel

  • cross-section study
  • collect information about past + present
  • treat information as if collected at different time
  • not ideal as many insecurities exists

TESTE DEIN WISSEN

what are advantages of a panel survey?

Lösung anzeigen
TESTE DEIN WISSEN
  • analyze change within unit of observation
    • within individuals over time
    • comapre individuals
  • establish direction + magnitude of causal relationship
    • determine temporal sequense of presued cause + effect
    • permit better tests of spuriousness
    • best with at elast 3 waves
  • reliability + accuracy of emasurement
    • personal fixed effects: attributes that are time invariant but amy bias observed relationship
    • recall bias: known threat to reliability of estimates (reduction possible by using prospective panels)

TESTE DEIN WISSEN

what are challenges of panel survey?

Lösung anzeigen
TESTE DEIN WISSEN
  • Measurements error
    • diff. btw. true vlue of variable and measured variable
    • present in all surveyys esp. panel surveys due to repeated exposure to similar stimuli
  • Attrition
    • respondents stop participating
    • can result in biased estimates in relation to target population

TESTE DEIN WISSEN

what are measurement errors?

Lösung anzeigen
TESTE DEIN WISSEN

classical measurement error

systematic time-in-sample error

Lösung ausblenden
TESTE DEIN WISSEN

explain the classical measurement error and possible solutions

Lösung anzeigen
TESTE DEIN WISSEN

classical measurement errors:

  • respondents geuss their answers
  • mistakes in coding/ transcribing data
  • oragnisational -> mismatch files of respondents from different survey rounds


possible solutions: key features: random + uncorrelated over time

  • change wording, order, number of questions
  • change data colleciton mode
  • change proxy respondents

what is a survey?

Lösung anzeigen
TESTE DEIN WISSEN
  • method to collect information to describe, compare, explain individual + societal knowledge, values, preferences, behaviour
  • information is systematically collected using relatively large sample from population
  • questions asked relate to not easily accessible information
  • aim of research: use information to compute sample statistics (= estimates of population values)
