Test1 Flashcards
-the variable the researcher is manipulating
Independent variable
Pre- existing group(male,female)
Subject variable
The variable the scientist is measuring
Dependent variable
Numeric values name the attribute uniquely
Nominal
Attributes can be rank-ordered, distance between attributes have no meaning
Ordinal
Distance between attributes does have meaning, but there is no true 0-point.
Interval
There is an absolute 0 and a meaningful reaction can be had from the data.
Ratio
(Type of data) Narrative, tends to focus on meaning, usually collected in “natural” environments
Qualitative
(Type of data) Numerical, tends to focus on behavior, may be collected in either “laboratory” or “natural” environments
Quantitative
Does not have fractions(decimal), not on a continuum
Discrete
Can be measured in whole numbers or fractions(decimals), relative positions along the continuum indicates more or less or what you are measuring. Measured along a continuum.
Continuous
Describes phenomena (types of research) Identifies at least one variable.
Descriptive research
(Types of research) examines relationships, two or more variables are measured to determine wether they relate to each other.
(Words in H1,RQ) association, relationship
Correlational research
(Types of research) examines differences in pre existing groups(ex.men,women), two or more pre existing groups are compared to some variable, has at least one subject variable and one dependent variable.
Quasi-experimental (causal comparative) research
(Types of research) Attempts to determine causality, has at least one independent variable and one dependent variable and identifies them .
(Wording of H1, RQ) uses simple language such as cause,affect, change, influence
Experimental research
Stated as a question, simple, answerable through empirical methods, directional when possible
Research question (RQ)
Statement about expected results, testable, related to RQ
Hypothesis (H1)
(Types of hypothesis)The hypothesis you support(your predictions)
Alternative hypothesis
(Types of hypothesis) hypothesis that describes the remaining possible outcomes
Null hypothesis(H0)
Refers to the tail of distribution on the outcome variable and thus identifies a particular direction for the outcome.
One-tail hypothesis
When predictions do not specify a direction
Two-tailed hypotheses
When creating a question for a questionnaire ask?
Is the question nesisary?
Is the question useful?
Is more than one question needed to adequately asses the construct?
IRB Concerns
Social standard, real and procieved coercion, psychological and physical harm, legal and financial harm, harm to dignity, informed consent
Any well-defined set of units for analysis
Population
A subset of a population collected through a systematic procedure called a ______ing method. Estimate a value of a population.
