Glossary of Scientific Terms

This glossary provides definitions of many of the terms used in the guides to conducting qualitative and quantitative research. The definitions were developed by members of the research methods seminar taught by Mike Palmquist in the 1990s and 2000s at the Colorado State University. 1

The goal of this type of research is to comprehend the particular group/culture through observer immersion into the culture or group.

A key element in experimental research is that participants in a study are randomly assigned to groups. In an attempt to create a causal model (i.e., to discover the causal origin of a particular phenomenon), groups are treated differently and measurements are conducted to determine if different treatments appear to lead to different effects.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]External Validity[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]The extent to which the results of a study are generalizable or transferable.

The test explores which variables in a data set are most related to each other. In a carefully constructed survey, for example, factor analysis can yield information on patterns of responses, not simply data on a single response. Larger tendencies may then be interpreted, indicating behavior trends rather than simply responses to specific questions.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Generalizability[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]The extent to which research findings and conclusions from a study conducted on a sample population can be applied to the population at large.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Grounded theory[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]Practice of developing other theories that emerge from observing a group.

In studies that do not explore causal relationships, only the first of these definitions should be considered when assessing internal validity. See also validity.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Internal Consistency[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]The extent to which all questions or items assess the same characteristic, skill, or quality.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Inductive analysis[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]A form of analysis based on inductive reasoning; a researcher using inductive analysis starts with answers, but forms questions throughout the research process.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Inductive[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]A form of reasoning in which a generalized conclusion is formulated from particular instances[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Independent Variable[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]A variable that is part of the situation that exist from which originates the stimulus given to a dependent variable.

Using Horton as an example again, she could code profanity individually and code \”damn\” and \”dammit\” as two separate concepts. Or, by generalizing their meaning, i.e. they both express the same idea, she could group them together as one item, i.e. \”damn words.”[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Level of Implication[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]One must determine whether to code simply for explicit appearances of concepts, or for implied concepts, as well. For example, consider a hypothetical piece of text about skiing, written by an expert. The expert might refer several times to \”???,\” as well as various other kinds of turns. One must decide whether to code \”???\” as an entity in and of itself, or, if coding for \”turn\” references in general, to code \”???\” as implicitly meaning \”turn.\” Thus, by determining that the meaning \”turn\” is implicit in the words \”???,\” anytime the words \”???\” or \”turn\” appear in the text, they will be coded under the same category of “turn.\”[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Link[/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]In hypertext, a pointer from one node to another[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=\”1/4\”][vc_column_text]Matched T-Test [/vc_column_text][/vc_column][vc_column width=\”3/4\”][vc_column_text]A statistical test used to compare two sets of scores for the same subject.
