Research Methods WEEK 2 Flashcards
The degree to which two variables are related
Correlation
quantifies the association between the two variables ranging from -1.0 to +1.0.
Correlation CoEfficient
A correlation of 0 means
the two variables are unrelated
A high correlation of close to -1.0 or +1.0 means
a participant’s score on one variable is a good predictor of the other
Correlation does not imply —–
imply causation
A systematic way of organising and explaining observations
Theory
Keeping procedures and methods the same
Standardised procedures
A valid design has ——- validity
internal validity
applicability to situations outside the laboratory is called —— ——–
External validity
To be generaliasable a study must have both
Internal Validity (A valid design)
and
External Validity (applicable outside the lab)
A measure that produces consistent results is called a —— ——-
Reliable Measure
A measure that accurately measures and assesses the construct it is intended to measure
Valid Measure
experiments or surveys that provide data that can be quantified, tabulated summarised and analysed are referred to as what type of research:
Quantative Research
Type of research that Explores a topic through methods such as interviews observation and case studies
Qualitative Research
Type of research that describes phenomena that already exists rather than manipulating variables. Unlike experiments , cannot unambiguously establish causation
Descriptive Research
In depth observation of a group or person
Case study
In-depth observation of a phenomena in its natural setting, outside the labaratory
Naturalistic Observation
Asking a large sample of people questions through interviews and questionaires
Survey Research
Manipulation of some aspect of the an experimental situation
Independant Variable
This component of a study helps to examine the impact on the way participants respond, in order to to assess cause and effect
Dependant variables
Experiment steps (6) FODSAD
- Framing hypothesis
- Operationalising variables
- Developing a standardised procedure
- Selecting and assigning participants
- Apply statistical techniques
- Drawing conclusions
Series of principals of ethics and professional practice
Code Of Ethics
An experiment or study is …… if it can produce the same results when repeated
Replicable
Making logical and rational assessments of inormation
Critical Thinking
A tentative belief about the relationship between two variables. Predicts the findings if a theory is correct
