Research Methods in LsD Flashcards
define what a research design is
the specific method a researcher uses to collect, analyze and interpret data
describe the strengths of a longitudinal research design
permits study of common patterns and individual differences, and relationships between early and later events and behaviours
list the three limitations of a longitudinal study
participant drop out, practice effects and cohort effects.
describe the strengths of a cross-sectional study
more efficient than longitudinal designs, not plagued by problems like drop out and practice effects
list the two limitations of a cross-sectional study
does not permit study of individual development trends, cohort effects
describe the strengths of a sequential study
permits longitudinal and cross-sectional comparisons, reveals cohort effects and tracks age-related changes efficiently
list the limitation of a sequential study
may have participant drop out, practice effects and cohort effects
what is the goal of a descriptive research design?
to create a snapshot of the current state of affairs
what are the advantages of a descriptive research design?
provides a relatively complete picture of what is occurring at a given time and allows the development of questions for further study
what are the disadvantages of a descriptive research design?
does not assess relationships among variables and may be unethical if participants do not know they are being observed
what is the goal of a correlational research design?
to assess the relationships between and among two or more variables
what are the advantages of a correlational research design
allows testing of expected relationships between and among variables and the making of predictions. can assess these relationships in everyday life events
what is the disadvantage of a correlational design study?
cannot be used to draw inferences about the causal relationships between and among the variables
what is the goal of an experimental design study?
to assess the causal impact of one or more experimental manipulations on a dependent variable
what is the advantage of an experimental design study?
allows drawing of conclusions about the causal relationships among variables
