Unit 1 Exp Design HMY Flashcards
Testable question
ones which can be answered through experimental inquiry and observation of the natural world.
Non-testable question
a claim that cannot be tested
Quantitative
data represented numerically, including anything that can be counted, measured, or given a numerical value.
Qualitative
relating to the nature or standard of something, rather than to its quantity.
Trials
an experiment in which you test something by using it or doing it for a period of time to see how well it works.
Observation
the action or process of carefully watching someone or something
Empirical evidence
the information obtained through observation and documentation or through an experiment.
Data
nformation such as facts and numbers used to analyze something or make decisions.
model science
a physicalrepresentation of a system of ideas, events or processes
Analogy
a comparison of the similarities between two concepts.
Prototype
an original model on which something is patterned
Hypothesis
an original model on which something is patterned
Variable
any item, factor, or condition that can be controlled or changed.
Procedure
A step-by-step description of how to perform an operation or process.
Precision
the closeness of two or more measurements to each other.
Accuracy
how close a measurement is to the true or accepted value.
Scientific method
the process of objectively establishing facts through testing and experimentation.
Control
an element that remains unchanged or unaffected by other variables.
Constant
The factors that do not change during the experiment.
Predict
a possible outcome of a scientific test based on logically reasoning about a particular scientific idea
Infer
a conclusion or educated guess drawn from observations as well as previous knowledge.
Dependent variable
the variable being tested in a scientific experiment. The dependent variable is “dependent” on the independent variable.
Independent variable
a variable that stands alone and isn’t changed by the other variables you are trying to measure.
Manipulated
Changed by the experiment in the design of the experiment.Changes as a result of the change in the independent Variable.
Manipulated variable
a factor that is purposefully and specifically changed by the experimenter Variables are manipulated, or altered on purpose, to identify cause and effect relationships.
Responding variable
the part of an experiment that a scientists measures and observes closely for a change or a response.
Sample size
the number of observations or individuals included in a study or experiment.
Validity
accurate information that is used in an unbiased way to convey a biological idea.
Trends in data
the general change in a variable with time.
Correlation
Used to describe the observed relationship between instances of two events.
Variability
he tendency at which traits in that population may vary
Mass
the amount of matter or substance that makes up an object
Volume
the amount of space occupied by a substance
Weight
the measure of the force of gravity acting on a body.
Percent
out of each hundred or per one hundred.
Rate
the speed with which a reaction takes place
Ratio
a relationship between two things when it is expressed in numbers or amounts.
Line graph
a chart that shows a line joining several points or a line that shows the relation between the points.
Bar graph
a graphical representation of data, quantities, or numbers using bars or strips.
pie graph
graph that represents the data in the circular graph. The slices of pie show the relative size of the data, and it is a type of pictorial representation of data.
Scatterplot
uses dots to represent values for two different numeric variables.
Claim
a statement saying that something happened a certain way or will happen a certain way
Evidence
anything that can be used to prove something
Reason
a statement or fact that explains why something is the way it is, why someone does, thinks, or says something, or why someone behaves a certain way.
Theory
an idea or set of ideas that is intended to explain facts or events.
Bias
a tendency to believe that some people, ideas, etc., are better than others that usually results in treating some people unfairly.
