Unit 1 Voc- Experimental Design Flashcards
testable question
Something that can be tested or proven through experimentation or observation
non-testable question
not capable of being tested
Quantitative
of, relating to, or involving the measurement of quantity
Qualitative
the characteristics or features of something, rather than its quantity
Trials
trying something to if it works or o get the best version of it
Observation
the act of careful watching and listening
Empirical evidence
any information you can collect through the processes of observation or investigation
Data
a collection of information that is gathered by observation, questioning or measurement
Model is science
where scientists represent something in the real world In a way that makes it easier to understand, or make predictions
Analogy
a comparison between two items based on a similar characteristic or feature
Prototype
the original model of which something is patterned
Hypothesis
an educated guess, or a guess you make based on information you already know
Procedure
a series of steps that must be taken to do something
Variable
a quantity that can change or vary, taking on different values
Precision
the quality or state of being precise
Accuracy
free from mistakes especially as the result of care
Scientific method
the process scientists follow to solve problems
Control
to exercise restraining or directing the influence over
Constant
to go on without pause
Predict
to declare in advance
Infer
to make facts based on information
Independent variable
a variable that stands alone and isn’t changed by the other variables your trying to measure
Dependent variable
something that depends on other factors
Manipulated variable
something that is changed on purpose in an experiment
Responding variable
a measurement that can change because of a change(s) of input data
Sample size
the number of observations or individuals included in a study or experiment
Validity
the quality or state of being valid
Trends in data
a change over time
Correlation
there is a relationship between two or more variables
Variability
the tendency to shift or change - of being “variable”
Mass
the amount of matter or substance that makes up an object
Volume
the amount of space an object takes up
Weight
the quality of being heavy
Percent
out of 100
Rate
a ratio of two measurements using different units
Ratio
compares one thing to another thing
Line graph
a plot of data points that are connected with a line
Bar graph
to show how something changes over time or compares items
Pie graph
a circular graph that is divided into sections that are proportional to the data they represent
Scatter plot
a graph of points that show the relationship between two sets of data
Claim
express your right to something
Evidence
something that is used to support an argument
Reason
a statement or fact that explains why something is the way it is
Theory
a group of linked ideas intended to explain something
Bias
our perception of the way things are or should be, even if it’s not accurate
