I don't know what a variable is
Is any event, situation, behavior, or individual characteristic that changes or varies
variable
Experimental study in which participants are not randomly assigned
quasi-experimental
Define an independant variable
the variable that is changed
identify the IDC, The amount of pollution is measured for different grades of petrol
I- Grade of Petrol
D- Amount of pollution
Controlled- Distance car moves, temp of engine
all the things that must remain the same in an experiment
Controlled variables
The variable that is manipulated and has two levels
independent
Relationships are studied by observing variables of interest, includes predictors
non-experimental
This type of method uses interviews and questionnaires to collect data
qualitative
Students measured the temperature of water at different depths in a dam
I- Depth
D- Temperature
Controlled- same Dam
This type of measures rate things such as heart rate, brain waves, and stress level
physiological
Any variable extraneous to the independent and dependent variable
third or confounding
Relationships are studied through direct manipulation and control of variables and participants are randomly assigned
experimental
This approach uses both quantitative and qualitative methods for collecting data
mixed-methods
This variable makes the experiment VALID
Controlled
the Dependant variable goes on the _____ axes of the
y axes
The outcome variable
dependent
The type design that "the third variable problem" is most likely to occur
non-experimental
This type of data collection uses past historical records
archival research
a statement of prediction of the results
Hyphothesis
Independent variable goes on which axes on a graph
x axis
The measurable definition of a variable
operational
This type of design is the highest quality
experimental
This type of data collection typically includes the use of pre-determined questions either individually or in groups.
interviews
A question asked before an experiment is done
Problem statement
The size of crystals formed when a molten rock crystallizes at different depths
I- Depth
D- Size of crystals
C- type of molten rock
