Q Flashcards
A data collection procedure, often used in personality measurement, in which a participant or independent rater sorts a set of stimuli (short descriptive statements printed on cards commonly are used) into various categories according to their relevance to or representativeness of the participant, under a restriction that a predetermined number of stimuli must be placed in each category
Q Sort
Loss of vision in one fourth, or one quadrant, of the visual field
Quadrantonopia
A type of research methodology that produces descriptive (non- numerical) data, such as observations of behavior or personal accounts of experiences
- The goal of gathering this is to examine how things look from different vantage points
- A variety of techniques are subsumed under qualitative research, including interviews, participant observation, and case studies
Qualitative Research
A measure that combines the quantity of life, expressed in terms of survival or life expectancy, with the quality of life
- The value of a year of perfect health is taken as 1; a year of ill health is worth less than 1; death is taken as 0
- The measure provides a method to assess the benefits to be gained from medical procedures and interventions
Quality Adjusted Life Years
The extent to which a person obtains satisfaction from life
- The following are important for a good one: emotional, material, and physical well being; engagement in interpersonal relations; opportunities for personal (eg; skill) development; exercising rights and making self determining lifestyle choices; and participation in society
- Enhancing this is a particular concern for those with chronic disease or developmental and other disabilities and for those undergoing medical or psychological treatment
Quality of Life
Introduction of the dimension of quantity (amount): the process of expressing a concept in numerical form, which may did in analysis and understanding
Quantification
A type of research methodology that produces numerical data, such as test scores or measurements of reaction time
- The goal of gathering this is to understand the nature of a phenomenon, particularly through the development of models and theories
- These techniques include experiments and surveys
Quantitative Research
One of the three values within a statistical distribution that divide it into equal sized fourth
- For example, the first (or lower) one of a distribution would be the data value below which are the lowest 25% of scores, the second one would be the data value below which are 51% to 75% of scores (or, conversely, above which are 25% of scores)
Quartile
Research in which the investigator cannot assign participants to experimental or control groups at random but can still manipulate the independent variable and limit the influence of extraneous variables to some degree
- An example of such a study, called a quasi experiment, is provided by a researcher assessing the memory performance of individuals with and without hearing loss: while the investigator cannot choose which people have hearing loss and which do not, he or she can decide upon the types of memory tasks to present and how to present them
- This is similar to non experimental research but distinguished by its retention of influence over the independent variable
Quasi Experimental Research
A set of questions asked to obtain information from a respondent about a topic of interest, such as his or her attitudes, behaviors, or other characteristics
Questionnaire
A method of selecting participants for a study in which a prespecified number of individuals with specific background characteristics, such as a particular age, race, sex, or education, is selected in order to obtain a sample with the same proportional representation of these characteristics as the target population
Quota Sampling
