VARIABLES
A variable that is manipulated by a researcher to explore its effects.
A. CONTROL VARIABLE
B. CONSTANT VARIABLE
C. DEPENDENT VARIABLE
D. INDEPENDENT VARIABLE
D. INDEPENDENT VARIABLE
This refers to the repetition of the basic experiment.
A. RANDOMIZATION
B. REPLICATION
C. TREATMENT GROUP
D. CONTROL GROUP
B. REPLICATION
It is known as experimental research design, is a method for studying how one variable affects another.
A. DESCRIPTIVE RESEARCH DESIGN
B. CORRELATIONAL RESEARCH DESIGN
C. CAUSE AND EFFECT RESEARCH DESIGN
D. EXPLORATORY RESEARCH DESIGN
C. CAUSE AND EFFECT RESEARCH DESIGN
It is separation technique that uses gravity to separate a liquid from a solid or two immiscible liquids.
A. MACERATION
B. DECANTATION
C. FILTRATION
D. DISTILLATION
B. DECANTATION
This refers to a variable that changes in response to another variable also known as the effect after treatment.
A. CONTROL VARIABLE
B. CONSTANT VARIABLE
C. DEPENDENT VARIABLE
D. INDEPENDENT VARIABLE
C. DEPENDENT VARIABLE
It refers to the assignment of the experimental units to the treatment or vice versa by chance
A. RANDOMIZATION
B. REPLICATION
C. TREATMENT GROUP
D. CONTROL GROUP
A. RANDOMIZATION (Random Assignment)
It is a research method that uses observation and measurement instead of experimentation.
A. NON-EXPERIMENTAL RESEARCH
B. EXPERIMENTAL RESEARCH
C. LONGITUDINAL RESEARCH
D. RESTROPECTIVE RESEARCH
A. NON-EXPERIMENTAL RESEARCH
Uses gravity to separate solids from a solution by allowing the heavier solids to settle at the bottom of a tank
A. SEPARATION
B. CHROMATOGRAPHY
C. SIEVING
D. GRAVITY FILTRATION
D. GRAVITY FILTRATION
A variable that is kept the same in an experiment or research study to ensure that outside influences don't affect the results.
Control Variable
It refers to a variable is not being tested, such as a test subject that does not receive any treatment
Control Group
It is a research design that uses random assignment of participants to groups to investigate cause-and-effect relationships between variables
TRUE EXPERIMENTAL RESEARCH DESIGN
It used to determine temperature at which it transitions from a liquid to a gas.
BOILING POINT
A variable that has a fixed value and remains the same throughout an experiment.
Constant Variable
It is a group of subjects in an experiment that receives a treatment or intervention, or has a variable changed for them.
Experimental Group
It is a research design that aims to estimate the impact of a program or event by comparing treated groups to control groups, but without random assignment.
QUASI-EXPERIMENTAL DESIGN
Determine the concentration of a substance in a solution by measuring its absorbance of a UV-Vis
UV-Vis Spectroscopy
A variable that is not being studied in a research study but can still affect the results
Extraneous Variable (Limiting Variable)
It is a type of control group which receives a treatment that is known to produce the expected effect. This group helps scientists determine if the experiment is working as planned
POSITIVE CONTROL GROUP
A rigorous design that test a hypothesis by comparing the data from an experimental group to a control group.
Experimental Research Design
Determine structure of organic compounds by analyzing the magnetic properties of an atomic nuclei
Nuclear magnetic resonance (NMR) Spectroscopy
