unit 1- list two- Experimental Design Flashcards
Claim
statements in science supported by data and research
Constant
The factors that do not change during the experiment.
Evidence
information collected via rigorous scientific methods that changes their belief in the truth of factual claims of the first to the fourth kind
Experimental bias
the unintentional influence of the experimenter’s expectations, beliefs, or preconceived notions on the outcome of a study or research experiment.
Experimental control
a group of samples that aren’t exposed to the changes or manipulations made by the scientist
Experimental procedure
the manner in which an experiment is carried out
Hypothesis
A statement about a specific research question, and it outlines the expected result of the experiment
Manipulated variable
a factor that is purposefully and specifically changed by the experimenter
Qual ( quality ) itative data
data representing information and concepts that are not represented by numbers
Quant ( quantity- numbers ) itative data
Quantitative = Quantity. Quantitative data are. measures of values or counts and are expressed as numbers
Reason
the capacity of consciously applying logic by drawing valid conclusions from new or existing information, with the aim of seeking the truth
Responding variable

Scientific method
the process of objectively establishing facts through testing and experimentation
Scientific model
a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes
Scientific question
one where an investigation can be designed and completed to find out the answer without having to do multiple, entirely different investigations to get there
Scientific theory
a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment
Trends in data
a general change in one variable compared to another over a period of time
Valid experiment
when the results are correct, or true
