Textbook Question
Chapter 1, Problem 10TYK
When researchers say that a scientific hypothesis must be falsifiable, they mean that:
a. the hypothesis must be proved correct before it is accepted astruth.
b. the hypothesis has already withstood many experimentaltests.
c. they have an idea about what will happen to one variable ifanother variable changes.
d. appropriate data can prove without question that thehypothesis is correct.
e. if the hypothesis is wrong, scientists must be able todemonstrate that it is wrong.

Students have asked these similar questions
When trying to figure out explanations for observations,scientists construct a series of possible hypotheses. Then they make predictions anda. test each hypothesis, using appropriate controls, todetermine which hypothesis is true.b. test each hypothesis, using appropriate controls, to rule outas many hypotheses as possible.c. use logic to determine which hypothesis is true.d. reject those that seem unlikely.
Which one of the following statements are not true about a scientific theory?
A.
Cannot be dedcued based on repeated observations without an experiment designed to test the hypothesis.
B.
Could be radically revised based on new scientific evidence.
C.
A basic principle derived from the study of nature that has never been disproven by scientific inquiry.
D.
It is a general and reliable explanation of important natural phenomena.
Which of the following statements best distinguisheshypotheses from theories in science?(A) Theories are hypotheses that have been proved.(B) Hypotheses are guesses; theories are correct answers.(C) Hypotheses usually are relatively narrow in scope; theorieshave broad explanatory power.(D) Theories are proved true; hypotheses are often contradictedby experimental results.
