100

The process through which a concept is turned into a measurable variable 


 

Operationalization 


100

A phrase used to describe how applicable the findings of a study are to other unobserved populations at other times, in other places in a quantitative study 


External Validity

100

A longitudinal research design in which a group of people who enter and/or exit institutions together are followed over time.

A Cohort Study 

100

A specific technique used to generate further information from participants after asking an initial interview question

Probing 

100

Covariance, Temporal Precedence, and Internal Validity need to established before making this type of claim

 Causality 

200

A comprehensive guide that indicates information about a dataset such as names of variables, a description of what they measure, information on how they were coded, and how missing values are dealt with

A Codebook 

200

The extent to which X→ Y rather than another variable

Internal Validity

200

Uses prolonged engagement and several methods (i.e. interviews, field observation, archives) to understand the norms and practices of a particular bounded context  

Ethnography 

200

A method that prefers mutually exclusive, closed-ended responses

Surveys 

200

Erroneously drawing conclusions about individuals based solely on observations of groups. An interpretation with a mismatch unit of analysis. 

Ecological Fallacy

300

A level of measurement that describes a variable whose attributes are rank order but do NOT have equal distance between attributes

Ordinal 

300

This concept describes the trade-off between strong causal control in laboratory experiments and their limited applicability to real-world settings—and vice versa

Mutual-Internal-Validity Problem

300

This design starts with quantitative analysis and follows with qualitative inquiry to explain and interpret those results

Explanatory Mixed Methods Design 

300

The study of recorded communication such as books, websites, images, mass media, and police reports

Content Analysis 

300

A measure that tells us how our sample might differ from the population we are studying solely by chance not sampling bias

Standard Error

400

The extent to which a test, tool, or measure accurately assesses a theoretical construct

Construct Validity  

400

This concept refers to the extent to which qualitative findings can extend beyond the original context, emphasizing shared processes and meaningful overlap across people and settings rather than generalizing to an entire population.


Transferability 

400

A type of quasi-experimental design in which changes in a dependent variable are monitored before and an interruption of a real-world intervention such as a change in law or policy

Interrupted Time Series Design

400


Stratified Sampling 

400

Higher order concepts that are derived from examining the relationship between inductive and deductive codes. They don’t ‘emerge’ but rather come about through the active process of analysis and interpretation

Themes 

500

An aggregated score or index created by combining two or more individual indicators, like Beck’s Depression Inventory

Composite Measure

500

Describes the truth value in qualitative research and can be established through prolonged engagement, member checks, memoing, triangulation, reflexivity, and other processes which determine the extent to which the findings are true.

Credibility 

500

If methodology is part of an iceberg, these two concepts lie beneath it:

The first refers to a set of ideas that explain phenomena. The second refers to a broader worldview that shapes how we understand the world.

Theory & Philosophical Assumptions 

500

A bottom-up qualitative analysis approach where codes are derived directly from the words of participants rather than pre-determined concepts or theory

Inductive Coding 

500

Describe the moment in which qual and quant components are integrated together. It can occur during design, data collection, data analysis, IN ADDITION to the interpretation phase. Without this, the study cannot be considered mixed methods.
