Textbook Question
Chapter 1, Problem 3TYK
Why can a hypothesis never be “proven” to be true?
- a. One can never collect enough data to be 100% sure.
- b. There may always be alternative untested hypotheses that might account for the results.
- c. Science is limited by our senses, and experimental error is always a factor.
- d. Science “evolves”; hypotheses and even theories are always changing.

Students have asked these similar questions
Can a theory be proven wrong?a. No, theories are exactly the same as facts.b. No, because there is no good way to test a theory.c. Yes, a new observation or interpretation of data could disprovea theory.d. Yes, theories are exactly the same as hypotheses.
which of the following best describes the logic of scientific inquiry?

b. If my prediction is correct, it will lead to a testable hypothesis
c. If my observations are accurate, they will support my hypothesis.
d. if my prediction is correct, my hypothesis is supported.

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.

- Why are alternative scientific theories to evolution not taught in public school? a. more theories would confuse students b. there are no viable scientific alternatives c. it is against the law d. alternative scientific theories are suppressed by the science establishmentarrow_forwardWhat is the difference between a scientific theory and a hypothesis? Why do scientists refer to basic scientific principles as “theories” rather than “facts”?arrow_forwardA person notices that her houseplants that are regularly exposed to music seem to grow more quickly than those in rooms with no music. As a result, she determines that plants grow better when exposed to music. This example most closely resembles which type of reasoning? Choose the correct answer. a. deductive reasoning b. inductive reasoning c. neither, because no hypothesis was made d. both inductive and deductive reasoningarrow_forward
- 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.arrow_forwardWhich statement about a hypothesis is incorrect? 1. It must be testable to be useful 2. It is a tentative explanation 3. It can be proven true 4. It can be unsupported by the data 5.

- Which of these statements is correct? a Scientists claim that they can prove a hypothesis b Scientists are happy to accept a hypothesis as soon as one of its predictions have been supported c A falsifiable hypothesis is one that is wrong d If the data contradict the predictions of the hypothesis, that hypothesis has been falsified e All of the abovearrow_forwardWhich 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.arrow_forwardWHAT ELSE CAN I ADD TO THIS: A hypothesis is "a proposed explanation for a set of observations. A prediction would occur after you form a hypothesis. You would make a prediction regarding your hypothesis and then work to gather more information, test the hypothesis through experiments and this will help you determine if your hypothesis is correct and make a conclusion. An example of this might be my phone continues to die quickly despite being fully charged. My hypothesis is that my phone is dying quickly because I have a defective battery. My prediction is that replacing the battery will solve the problem. I can then test that hypothesis by replacing the battery and determine if that solves the problem.arrow_forward
