Topic 9 Flashcards
What is used in inductive reasoning to construct general scientific principles?
specific testable observations
A hypothesis would be best defined as which of the following?
A probable explanation of an observation that is testable
When no connection exists between the variables the correlation is a?
coincidence
What is the order of the Scientific Method?
Observations, Questions, Hypothesis, Experiments, Conclusions, Theory
When does a hypothesis lead to a theory?
After being proven by multiple experiments
____ is an element, feature, or factor that is liable to vary or change.
variable
A hypothesis that is distinguished from a question would be which of the following?
must be testable in an experiment
Is a relationship between two variables in which one variable increases while the other variable decreases?
negative correlation
Is a relationship between two variables in which one variable increases causes the other variable to increase.
positive correlation
Deductive reasoning uses what to predict a specific result
known principles
Hypothesis
is a contrasting predictions that can be tested experimentally in a control and test experiment where a single variable is altered
Experiment
are tests of one or more hypotheses
Experimentation is done with control and changed variables. ex. (culturing microbes in laboratory conditions, repeating observations)
Observation
the first step and should be specific
Control
A variable in an experiment which is held constant in order to assess the relationship between multiple variables
Variables
are factor that influences a process, outcome, or observation
Conclusion
after experimentation and before the theory
there are two ways to arrive at a logical conclusion - inductive and deductive reasoning
Theory,
is developed based on many conclusions
Deductive reasoning
applies general principles to predict a specific results. (Uses known principles) Deductive reasoning is the reason mathematics and philology can be used to validity general ideas
Inductive reasoning,
logic flows opposite, as the specific observations to construct general scientific principles. Inductive reasoning leads to generalizations that then can be tested, and most biological studies use inductive reasoning
Correlation,
is a relationship between the independent and dependent variables. An indirect relationship of the variables signifies a correlation
Causation
is a relationship between the independent and dependent variables. A direct relationship shows causation, between the variables
Understand the process of the scientific method, in relation to hypothesis formation, and the Experimentation process
An specific observation is made
(Observing microbes using a microscope) which leads to the formation of questions, which then lead to development of hypothesis
A hypothesis is developed
(Possible suggested explanation for the presence of microbes)
Experimentation is done with control and changed variables. (culturing microbes in laboratory conditions, repeating observations)
A conclusion is made.
A Theory is developed based on many conclusions.
Understand the relationship between Correlation, Causation, and Coincidence.
Correlation is a relationship between the independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation, between the variables.
If no connection exists between the variables, then the correlation is a coincidence.
