Chapter 4: Qualitative Emphasis in Research Study Designs
Cronbach's alpha
AKA: Coefficient alpha 1- Collect data on scale from large sample of participants 2- Compute all possible correlations among the items
Discriminant delivery (def.)
AKA: Divergent validity AKA: Convergent validity An empirical test of the extent to which a self-report measure does not correlate strongly with measures of theoretically dissimilar constructs.
Case study (def.)
AKA: Idiographic research Qualitative research design in which a single individual, program, or event is studied in depth for a defined period of time.
Internal reliability (def.)
AKA: Internal consistency Study a participant gives a consistent pattern of answers, no matter how the researcher has phrased the question.
Primary informants (def.)
AKA: Key informant In an ethnographic study or similar qualitative design, a person who can provide especially useful information and insights and possibly also facilitate contacts with other helpful individuals
Categorical variables (def.)
AKA: Nominal variables Categorial levels of variables.
Correlation coefficient (def.)
AKA: r A common and efficient way to see if a measure if reliable

An empirical test of the extent to which a self-report measure correlates with the other measures of a theoretically similar construct. See also: discriminant validity.
What is another name of an observational measure?
Behavioral
A researcher wants to study the phone preferences of college students and has to classify the variables. He assigns each phone type a number in his study (e.g., Samsung = 1, iPhone = 2). How would you best describe the way he's classified his operational variables?
Categorical variables
Validity (def.)
Concerns whether the operationalization in measuring what is supposed to measure.
Interrater reliability (def.)
Consistent scores are obtained no matter who measures the variable. Example: Two or more independent observers will come up with consistent (or similar) findings.
What is the definition of reliability?
Defined as the consistency of the results of a measure. ONLY applies to self-report scales with multiple items. Examples: People that take Diener's five-item subjective well-being scale with multiple questions asking about the same construct in different ways. People that agree with the first item should agree with the second, third, and so on items.
Strength (def.)
Description of an association indicating how closely the data points in a scatterplot cluster along a line of best fit drawn through them.
Restorying (def.)
In a narrative inquiry research, an approach to data anlysis wherein researchers first (a) analyze participants' recollections and other data resources in a search for key themes and then (b) reorder the data to craft rich narratives that provide a better understanding of the setting, context, time period, and/or sequence of events.
Gatekeeper (def.)
In an ethnographic study, a person who can smooth the way for a researcher's entrance into a particular cultural group.
Three-interview series (def.)
In phenomenological research, a method of interviewing that entails conducting three interviews with each participant; the first focuses on the participant's life history, the second focuses on the details of the participants' lived experiences, and the third encourages the participant to reflect on possible meanings of their experiences.
Participant observation (def.)
In some ethnographic studies, an approach in which researchers immerse themselves in the daily lives of the people they are studying.
What kind of reliability would be involved in two or more observers coming up with the same findings as one another?
Interrater reliability
Which of these statements is the BEST way to rephrase that qualitative research is often an iterative process of data collection and analysis?
It involves collecting data and analyzing it before collecting more data and analyzing that.
People who have already been diagnosed with clinical depression should have high scores on a measure that is testing for depression while people who are not depressed should test low on the same scale. This statement relates to what concept?
Known-groups paradigm
Quantitative variables (def.)
Levels are coded with meaningful numbers
Ratio scale (def.)
Measurement applies when the numerals of a quantitative variable meet two criteria: 1- Equal intervals and when the value of 0 truly means "none" 2- When the value of 0 truly means "none" or "nothing" of the variable being measured.
Interval scale (def.)
Measurement scale that applies to the numerals of quantitative variable that meets two conditions: 1- Numerals represent equal intervals (distances between levels) 2- No "true zero" (person can get a score of 0, but the 0 does not really mean "nothing").
Ordinal scale (def.)
Measurement scale that applies when the numerals of a quantitative variable represent a ranked order. Example: Movie store might rank top 5 highest grossing movies. Based on this, we know that movie #1 sold more than #2, #2 sold more than #3 and so on but we do not know the amount of revenue that separates any of the box office results.
How might grounded theory design best be summarized?
Method for developing theories based on systematically gathering and analyzing data.
Known-groups paradigm (def.)
Method for establishing criterion validity, in which a researcher tests two or more groups who are known to differ on the variable of interest, to ensure that they score differently on a measure of that variable.
Convergent designs (def.)
Mixed-methods design in which a researcher collects both quantitative and qualitative data in parallel, usually at the same time and with respect to the same general research problem; similar weight is given to the two types of data, with the hope that they will yield consistent or complementary findings.
