Unit 1 Experimental Design JMA Flashcards
one that is answered through designing an investigation or experiment where one thing is changed to observe how it will affect something else.
Testable Question
Questions that cannot be answered by direct observation or by evidence gathered through experimental inquiries
Non-Testable Question
relating to, measuring, or measured by the quantity of something rather than its quality.
Quantitative
relating to, measuring, or measured by the quality of something rather than its quantity.
Qualitative
a test of the performance, qualities, or suitability of someone or something.
Trails
the action or process of observing something or someone carefully or in order to gain information.
Observation
The concept of evidence is the basis of philosophical evidentialism, an epistemological thesis according to which a person is justified in believing a given
Empirical Evidence
facts and statistics collected together for reference or analysis.
Data
a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Model in Science
a comparison between two things, typically for the purpose of explanation or clarification.
Analogy
a first, typical or preliminary model of something, especially a machine, from which other forms are developed or copied.
Prototype
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Hypothesis
not consistent or having a fixed pattern; liable to change.
Variable
an established or official way of doing something.
Procedure
the quality or state of being correct or precise.
Accuracy
the quality, condition, or fact of being exact and accurate.
Precision
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Scientific Method
the power to influence or direct people’s behavior or the course of events.
Control
occurring continuously over a period of time.
Constant
say or estimate that (a specified thing) will happen in the future or will be a consequence of something.
Predict
deduce or conclude (information) from evidence and reasoning rather than from explicit statements.
Infer
a variable (often denoted by x ) whose variation does not depend on that of another.
Independent Variable
a variable (often denoted by y ) whose value depends on that of another.
Dependent Variable
is a part of an experiment that you can change to see how other variables respond
Manipulate Variable
the number of observations or individuals included in a study or experiment.
Sample Size
the factor that is measured by the scientist as a result of the effects of the manipulated variable.
Responding Variable
the general change in a variable with time.
Trends in Data
the quality of being logically or factually sound; soundness or cogency.
Validity
a mutual relationship or connection between two or more things.
Correlation
the tendency to shift or change — of being “variable.”
Variability
a coherent, typically large body of matter with no definite shape.
Mass
the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
Volume
a body’s relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
Weight
by a specified amount in or for every hundred.
Percent
the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Ratio
a measure, quantity, or frequency, typically one measured against some other quantity or measure.
Rate
graphical representation of information that changes over a period of time.
Line Graph
a diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width.
Bar Graph
a type of graph representing data in a circular form, with each slice of the circle representing a fraction or proportionate part of the whole.
Pie Graph
state or assert that something is the case, typically without providing evidence or proof.
Claim
a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
Scatterplot
the available body of facts or information indicating whether a belief or proposition is true or valid.
Evidence
a cause, explanation, or justification for an action or event.
Reason
a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
Theory
prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Bias
