Unit 1 List 1 Exp. Design CMH Flashcards
Testable Question
questions that can be answered through experimental inquiry and observation of the natural world.
Non-Testable Question
cannot be answered by direct observation or by evidence gathered through experimental inquiries
Quantitative
relating to, measuring, or measured by the quantity of something rather than its quality.
Qualitative
relating to, measuring, or measured by the quality of something rather than its quantity.
Trials
test to assess its suitability or performance.
Observation
action or process of observing something or someone carefully or in order to gain information.
Empirical Evidence
information obtained through observation and documentation of certain behavior and patterns or through an experiment.
Data
facts and statistics collected together for reference or analysis.
Model is Science
a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Analogy
comparison between two things,
typically for the purpose of explanation or clarification.
Prototype
first, typical or preliminary model of something, especially a machine, from which other forms are developed or copied.
Hypothesis
supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Variable
any characteristic, which varies from individual to individual
Procedure
established or official way of doing something.
Precision
quality, condition, or fact of being exact and accurate.
Accuracy
quality or state of being correct or precise.
Scientific method
empirical method for acquiring knowledge using question, Research, hypothesis, experiment, data analysis, conclusion, and communication.
Control
element that remains unchanged or unaffected by other variables.
Constant
part that doesn’t change during the experiment.
Predict
say or estimate that (a specified thing) will happen in the future or will be a consequence of something.
Infer
deduce or conclude (information) from evidence and reasoning rather than from explicit statements.
Independent Variable
a variable (often denoted by x ) whose variation does not depend on that of another.
Dependent Variable
a variable (often denoted by y ) whose value depends on that of another.
Manipulated Variable
variable that you control and change based on the experiment.
Responding variables
changes as a result of the manipulated variable.
Sample size
number of observations or individuals included in a study or experiment.
Validity
how accurately a method measures what it is intended to measure.
Trends in data
general change in a variable with time.
Correlation
correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bi variate data.
Variability
lack of consistency or fixed pattern; liability to vary or change.
Mass
quantitative measure of inertia, a fundamental property of all matter.
Volume
amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
Weight
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.
Percent
proportion of an amount, group or set.
Rate
change in concentration over the change in time.
Ratio
quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
“the ratio of computers to s
Line Graph
graphs that can be used to show how something changes over time.
Bar Graph
is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent.
Pie Graph
graph representing data in a circular form, with each slice of the circle representing a fraction or proportionate part of the whole.
Scatterplot
uses dots to represent values for two different numeric variables.
Claim
state or assert that something is the case, typically without providing evidence or proof.
Evidence
available body of facts or information indicating whether a belief or proposition is true or valid.
Reason
cause, explanation, or justification for an action or event.
Theory
supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
Bias
prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
