Science skills Flashcards
Aim
a statement
outlining the purpose of
an investigation
Hypothesis
a testable
prediction about
the outcome of an
investigation
Population
the group of people
who are the focus of the
research and from which
the sample is drawn
Independent variable
the variable for which
quantities are manipulated
(controlled, selected,
or changed) by the
researcher, and the
variable that is assumed to
have a direct effect on the
dependent variable
Dependent Variable
the variable the researcher
measures in an experiment
for changes it may
experience due to the
effect of the independent
variable
Controlled Experiment
a type of investigation
in which the causal
relationship between two
variables is tested in a
controlled environment;
more specifically, the
effect of the independent
variable on the dependent
variable is tested while
aiming to control all other
variables
Controlled Variables
variables other than the
IV that a researcher holds
constant (controls) in an
investigation, to ensure
that changes in the DV
are solely due to changes
in the IV
Case study
an in-depth
investigation of an
individual, group, or
particular phenomenon
(activity, behaviour, event,
or problem) that contains
a real or hypothetical
situation and includes the
complexities that would
be encountered in the
real world
Correlational Study
a type of non-experimental
study in which researchers
observe and measure the
relationship between two
or more variables without
any active control or
manipulation of them
Experimental group
The group of participants in an experiment who are exposed to a manipulated IV
Control Group
Group of participants in an experiment who receive no experimental treatment or intervention to serve as a baseline for comparison
Within subjects design
