specific method of estimating the internal consistency reliability of a measure– can be thought of as analogous to the average of all possible split half correlations
ValidityCrucial for any kind of meaningful measurement, validity deals with accuracy or precision ofmeasurementConstruct Validity:used to determine how well a test measures what it is supposed to measure,construct validity is usually verified by comparing the test to other tests that measure similarqualities to see how highly correlated the two measures areoTranslation Validity:type of construct validity related to how well you translate the ideaof your measure into its operationalizationoFace validity:checks that ‘on its face’ the operationalization seems like a goodtranslation of the constructoContent validity:check of the operationalization against the relevant content domain forthe construct (extent to which items on a test are fairly representative of the entiredomain the test seeks to measure)oPredictive Validity:type of construct validity based on the idea that your measure isable to predict what It theoretically should be able to predictoConcurrent Validity:operationalizations ability to distinguish between groups that itshould theoretically be able to distinguish between (how well a new test compares to awell-established test)oConvergent Validity:degree to which the operationalization is similar to (converges on)other operationalizations to which it should be theoretically similaroDiscriminant Validity:degree to which the operationalization is not similar to (divergesfrom) other operationalizations that it theoretically should not be similar toIf you can demonstrate that you have evidence for both convergent anddiscriminate validity, then you’ve demonstrated that you have evidence forconstruct validity –but neither one alone is sufficient for establishing constructvalidityoOperationalization: translating a construct you wanted to measure into the real measureChapter 7 – Survey ResearchSelecting the Survey Method – questions you might ask;population issuessampling issuessamplingissuesbias issuesadministrative issuesCan the population units be identifiedIs the population literateAre there language issues?Will the population cooperateWhat are the geographic restrictionsWhat data is available?Can respondents be foundWho is the respondentCan all members of the population be sampledAre response rates likely to be a problemWill incentives for participation helpWhat types of questions can you ask
Will filter questions be neededCan question sequence be controlledWill long response scales be usedCan social desirability be avoidedCan interviewer distortion and subversion be controlledCan false respondents be avoidedCostsTimeFacilitiesPersonnelSurvey FormatDichotomous response format: question response format that allows the respondent to choosebetween only two possible responses (Yes/No, True/False, Agree/Disagree)Nominal response format: has a number beside each choice where the number has no meaningother than a placeholder (2 for a lawyer)
