Unit 1 Exp Design N.A Flashcards
Testable question
A question that can be answered through experimental inquiry.
Non-testable question
A Questions that cannot be answered by evidence gathered through experimental inquiries.
Quantitative
Quantitative data is numbers-based, countable, or measurable.
Qualitative
Qualitative data is interpretation-based, descriptive, and relating to language.
Trials
A tryout or experiment to test quality, value, or usefulness.
Observation
An act or instance of noticing or perceiving of information from a primary source.
Empirical evidence
Information obtained through observation of certain behavior and patterns or through an experiment.
Data
Information that has been translated into a form that is efficient for movement or processing.
Models in science
A physical and/or mathematical representation of a system of ideas, events or processes.
Analogy
A comparison of two otherwise unlike things based on resemblance of a particular aspect.
Prototype
A working model that is used to test a design solution.
Hypothesis
A concept or idea that you test through research and experiments.
Variable
Anything that can change or be changed within an experiment.
Procedure
A detailed, step-by-step list of everything you will do in your experiment.
Precision
How close measurements of the same item are to each other.
Accuracy
How close a measurement is to the true or accepted value.
Control
An element that remains unchanged or unaffected by other variables.
Scientific method
The process of objectively establishing facts through testing and experimentation.
Infer
The process of drawing conclusions based on evidence and reasoning.
Constant
The factors that do not change during the experiment.
Predict
A possible outcome based on logically reasoning about a particular scientific idea.
Independent variable
A variable that stands alone and isn’t changed by the other variables.
Dependent variable
What you measure in the experiment and what is affected during the experiment.
Manipulated variable
A factor that is purposefully and specifically changed.
Responding variable
The part of an experiment that you measure and observe closely for a change or a response.
Sample size
The number of participants or observations included in a study.
Validity
How accurately a method measures what it is intended to measure.
Trends in data
The general change in a variable with time.
Variability
Describes how far apart data points lie from each other.
Correlation
The relationship between variables.
Mass
A measure of how much matter makes up a physical object.
Volume
The amount of space the object takes up.
Weight
the force exerted on a body or object by gravity.
Percent
A relative value indicating hundredth parts of any quantity.
Rate
The change in concentration over the change in time.
(rate of change)
Ratio
a comparison in terms of a quotient of two numbers like a and b. (a:b)
Line graph
A graphical display of information that changes continuously over time.
Bar graph
A type of graph in which each column represents a categorical variable.
Pie graph
A way of summarizing or displaying the different values of a given variable.
Scatterplot
Identifies a possible relationship between changes in two different sets of variables.
Claim
A statement or answer to a scientific question.
Evidence
Information, facts or data supporting a claim, assumption or hypothesis.
Reason
A problem-solving process that involves critical thinking in relation to content.
Theory
A well-substantiated explanation of an aspect of the natural world.
Bias
A personal judgment for or against one side in a dispute.
