PR2 Flashcards
uses random
assignment (like flipping a coin, to
decide which group each person will be
in) to ensure fair testing, making it
easier to see if something really works
True Experimental
the participants
are assigned to groups based on
certain criteria or circumstances rather
than randomly.
Quasi Experimental
design
does not alter a variable
NON-EXPERIMENTAL
when researchers want
to gather information about a situation
without trying to figure out what causes
it. It focuses on collecting statistics and
describing characteristics
Descriptive
aims to understand
differences between groups or
variables in a non-experimental way.
Researchers compare and contrast
these groups to identify potential
reasons for those differences.
Comparative
researchers
want to explore the relationship
between two variables and understand
how they are related, whether
positively or negatively.
Correlational Design
refers to the entirety or
group of people, objects or any subject
of interest that is intended to generalize
the results of your study.
Population
is the group of individuals who
actually participate in your study. A
sample must appropriately
represent the population.
Sample
is a process in which a
researcher chooses her sample and
sample is the group of individuals who
actually participate in your study
Sampling
or random
sampling
means every individual is given an
equal chance to be selected.
Probability sampling
- the
chance of selection is the same for
every member of the population
Simple random technique
follows specific steps and procedures in doing the random selection of the samples
Systematc random sampling
also sometimes called quota involve dividing your population into homogeneous subgroup
Stratified random sampling
a conducted size of population is to large to perform simple random sampling
Cluster random sampling
the quality of the instrument being functional within its specific purpose
Validity
