Unit 1 Exp Design AL Flashcards
Testable
Able to be tested or tried.
Non-testable
Not able to be tested or tried.
Quantitative
Measuring by numbers rather than images.
Qualitative
Measuring by images, pictures, or opinions rather than being measured by numbers.
Trials
A test of the performance, quality, or suitability of something/someone.
Observation
Noticing or observing what is going on in an experiment.
Empirical Evidence
Information obtained through observations of an experiment.
Data
Facts/statistics collected together for analysis.
Scientific Model
A physical mathematical/conceptual representation of a system of ideas, events, and processes.
Prototype
A first attempt at something, something that the other forms of it are developed or copied from.
Analogy
A comparison between two things, usually for the purpose of clarifying something or making something easier to relate to.
Hypothesis
An educated guess designed to predict an experiment.
Variable
A trait, condition, or factor that can exist in differing amounts or types.
Procedure
A set of rules that are created by an entity that everyone must follow.
Accuracy
How accurate or how close you are to something.
Precision
How precise you are; or more accurately how exact you are.
Scientific Method
A method that consists of observation, measurement, experimentation, formulation, testing, and hypothesis.
Control
An element that remains unchanged by other variables.
Constant
The part that doesn’t change during the experiment.
Predict
Making an educated guess to something that will happen in the future.
Infer
Making an educated guess based on the context provided.
Independent Variable
A variable that is independent of other variables.
Responding variable
The part of an experiment that scientists monitor closely to see how it responds.
Dependent variable
A variable that depends on other variables.
Sample size
The number of observations or people in a study.
Manipulated variable
The part of the experiment that changes so the experimenter can observe how other variables respond.
Variability
Something that is liable to change.
Volume
The amount of space that a substance occupies; an example of this would be the ocean is about 321,003,271 cubic miles.
Validity
How valid something is, how reliable something is.
Mass
The quantity of matter within an object.
Trends in data
This is basically the same thing as patterns of data; simply patterns that the data can show us.
Correlation
A mutual relationship or a connection between two or more things.
Weight
The heaviness of something.
Rate
The speed with which a reaction takes place.
Percent
A fraction of something or a numerical value representing something.
Ratio
A relationship between two things that is expressed as a value or an amount.
Line graph
A graph that is typically used to show change over time.
Bar graph
A diagram in which the numerical values of variables are represented by the height and width of the bar.
Claim
A concluding statement that is used to explain a cause and effect relationship.
Scatter plot
A graph in which the values of two variables are plotted along two axes,.
Pie graph
A graph that uses percentage to fill in a part of a circle, usually used when there are lots of different variables that are being measured.
Evidence
Something that proves something.
Reason
Theory
A highly educated guess that uses several proofs to validate itself.
Bias
An aversion or support given to something due to personal experience.
