Exploratory | | effects of taking a pretest or knowing the results or pretest on posttest scores |
History | | a design that is time related and occurs over time (e.g. pain relief, learning, healing) |
Primary | | subjects respond i a certain manner because they are aware of being observed or know they are in a study |
Reviewofliterature | | changes that occur due to subject changes during the study that can influence results |
simple | | is an influence that produces a distortion in the study results |
Dependentvariable | | the investigation of phenomena that lends to precise measurement and quantification |
Survey | | a hypothesis that predicts a relationship between two variables but does not stipulate the direction |
Retrospective | | a Nonexperimental design that studies, observes, counts, describes, and classifies phenomena |
Maturation | | a design that collects data at more than one point in time (trends, Cohort type of trend study) |
Quantitative | | a hypothesis states that no difference exists between two variables |
Betweensubject | | a hypothesis states a relationship or direction exists between variables |
Internalvalidity | | when some event besides the experimental treatment occurs during course of study and it influences the dependent variable |
Prospective | | a Nonexperimental design that is a self report data that can be collected via phone, mail or through personal contact |
Qualitative | | a design that randomly assigns to one of 4 groups and is the most powerful experimental design |
Descriptive | | can be a negative or positive number that shows a relationship to be strong or weak with a cutt off at 0.7 |
Extraneous | | a hypothesis with a relationship between one independent and one dependent variable |
Complex | | limiting extraneous variables |
Bias | | this setting is ideal for controlling extraneous variables |
Control | | a journal article written by the researcher themselves |
Hawthorneeffect | | A way to conduct nonexperimental studies that start in present time and follow into the future |
Laboratory | | the investigation of phenomena that typically is in-depth and holistic, throught the collection of rich narrative materials |
Matching | | a journal article that explains another researcher's work |
Non-directional | | variables that are external influences and must be held constant |
Systematic | | The outcome variable, observed for change |
Time | | a design that compares groups of subjects; those who receive something vs those who don't |
Null | | a hypothesis that predicts a relationship in an expected direction "worse/better" |
Withinsubject | | states the predicted relationship between 2 or more variables |
Secondary | | if a researcher's characteristics or behaviors influence subjects behaviors |
Randomization | | a bias consistent across all participant and situations |
Directional | | ensures comparable groups sot that extraneous variables are spread evenly |
Correlation | | observed, introduced or manipulated to determine the effect it has on another variable |
Solomon4group | | using knowledge of subject's characteristics to form comparison groups |
Research | | a way to conduct nonexperimental studies that "Ex pos Facto" |
Experimentaleffect | | a hypothesis with a relationship between 2 or more independent variables, 2 or more dependent variables |
Crosssectional | | a extensive, exhaustive and critical examination of publications relevant to the research project |
QuasiExperimental | | a Nonexperimental design that goes beyond observing and describing and focuses on the full narture of the phenomena |
Independentvariable | | a design that compares equal groups by manipulation of independent variables and measurement of dependents, uses statistics and stringent control |
Hypotheses | | a design that collects data at one point in time |
Testing | | a design where there is no comparison group or subjects are not randomly assigned to groups |
TrueExperimental | | concerns the degree to which changes in the dependent vrariable can be attributed to the independent variable |
Longitudinal | | a design that compares results for the same person under two different conditions or at two points in time |
