Figure 1.6 In the example below, the scientific method is used to solve an everyday problem. Order the scientific method steps (numbered items) with the process of solving the everyday problem (lettered items). Based on the results of the experiment, is the hypothesis correct? If it is incorrect, propose some alternative hypotheses. Observation Question Hypothesis (answer) Prediction Experiment Result There is something wrong with the electrical outlet. If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it. My toaster doesn’t toast my bread. I plug my coffee maker into the outlet. My coffeemaker works. Why doesn't my toaster work?
The type of logical thinking that uses related observations to arrive at a general conclusion is called_______. a. deductive reasoning b. the scientific method c. hypothesis-based science d. inductive reasoning
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.

At the conclusion of a good scientific studyGroup of answer choicesthe hypothesis is re-examined in light of the results and modifications are made in either the hypothesis or the experimental designthe hypothesis is proven or disproven and a theory is developedthe study is published and a guess as to why a phenomenon occured becomes facta debate typically ensues about whether the findings are legitimate
Select all that are included in the model representation of scientific inquiry. Refine hypotheses Evaluate efficacy of statistical models Research the problem Observe Analyze the results Concur with colleagues
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.
___________ __________ is the precise repetition of an experiment or expansion of observed data to provide verification; the procedure by which hypotheses and theories are verified, modified, or discarded. Group of answer choices A-empirical hypothesizing B-pscientific testing C-theoretical investigating D-qualitative observing E-quantitative reasoning
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.
Identify each statement below as S if it can be tested scientifically or N if it is non-empirical knowledge. Explain your answer. a. Leonardo da Vinci is a better painter than Picasso is. b. Alcohol consumption by pregnant women may cause birth defects in their babies. c. There is a God. d. The sun rises in the east every morning.
A hypothesis can be defined asa. a belief based on knowledgeb. knowledge based on beliefc. a scientific explanation that is subject to testingd. a theory that has been thoroughly tested
Inductive reasoning begins with a theory -- is true or false? Research studies should never have assumptions, as these should havve been controlled for -- is true or false?
