Reviewing Research Terminology
Accuracy
A term used in survey research to refer to the match between the targetpopulation and the sample.
Apparency
Clear, understandable representation of the data
Bell Curve
A frequency distribution statistics. Normal distribution is shaped like a bell.
Case Study
The collection and presentation of detailed information about a particularparticipant or small group, frequently including the accounts of subjectsthemselves.

Causal Model
A model which represents a causal relationship between two variables.
Confidence Level
The specific probability of obtaining some result from a sample if it did notexist in the population as a whole, at or below which the relationship will beregarded as statistically significant
Correlation
1) A common statistical analysis, usually abbreviated as r, that measures thedegree of relationship between pairs of interval variables in a sample. Therange of correlation is from -1.00 to zero to +1.00. 2) A non-cause and effectrelationship between two variables.
Credibility
A researcher’s ability to demonstrate that the object of a study is accuratelyidentified and described, based on the way in which the study was conducted
Dependability

Empathic Neutrality
A quality of qualitative researchers who strive to be non-judgmental whencompiling findings
Face Validity
How a measure or procedure appears.

Hypertext
A nonsequential text composed of links and nodes
Hypothesis
A tentative explanation based on theory to predict a causal relationshipbetween variables.
Independent Variable
A variable that is part of the situation that exist from which originates thestimulus given to a dependent variable. Includes treatment, state of variable,such as age, size, weight, etc.
Interrater Reliability
The extent to which two or more individuals agree. It addresses theconsistency of the implementation of a rating system.
Level of Analysis
Chosen by determining which word, set of words, or phrases will constitute aconcept. According to Carley, 100-500 concepts is generally sufficient whencoding for a specific topic, but this number of course varies on a case by case basis.

Matching
Process of corresponding variables in experimental groups equally feature forfeature.
Narrative Inquiry
A qualitative research approach based on a researcher’s narrative account ofthe investigation, not to be confused with a narrative examined by theresearcher as data
Node
In hypertext, each unit of information, connected by links
Population
The target group under investigation, as in all students enrolled in first-yearcomposition courses taught in traditional classrooms. The population is theentire set under consideration. Samples are drawn from populations.
