3)If a scientist does an experiment and gets a result, but no other scientists are able to repeat the experiment and get the same result, what does that mean? Select one: a. The first scientist is a quack b. The other scientists don't know what they're doing c. Something about the hypothesis, prediction, or experimental design is wrong in the first experiment d. The first scientist's hypothesis is wrong e. There's no way to do the investigation

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.
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?
Which of the following are characteristics of scientific theories? (select all that are correct) a) An guess at how the world works b) An hypothesis that has been supported across many experiments c) An untested idea d) An expert's opinion e) A testable idea about how the world works that is supported by objective data from multiple sources. f) An hypothesis that has been supported by some research but not supported by other research.
1. Essentially, what is science?a) collection of factsb) systematic process for learning about the natural worldc) beliefs about the natural world based on faithd) the search for ultimate reality 2. The ultimate goal of science is to provide evidence that _____ .a) proves things absolutely trueb) disproves religious beliefsc) increases the quality of life for the greatest number possibled) is always applied to solving problems
Theories change as new information becomes available. Which actions are most likely to lead to the discovery of new information? Check all that apply. 1.repeating experiments using the same experimental method each time 2.repeating experiments using the technology available at the time of the original experiment 3.repeating an experiment using the latest technology 4.developing a new experimental method to test an existing hypothesis
The 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.
Which of the following is not correctly linked?a. model: a representation of an object used in an experimentb. standard deviation: a form of statistical analysisc. principle: a theory that is not supported by experimental evidenced. data: the results of an experiment or observation
I answered with a and c but keep getting told its the wrong answer. Which of the following is not a component of effective experimental designs in the early stages of a scientific study? Select one or more: a. small sample sizes b. experimental groups taking a placebo c. double blind experiments d. short duration e. animal models f. repetitive testing
Which of the following is not true of science?a. Science is based on the premise that all events can be traced to natural causes.b. Important science can be based on chance observations.c. A hypothesis is basically a wild guess.d. Scientific theories can potentially be disproved.
Which of the following is used when testing a prediction?a. observationsb. inductive reasoningc. controlled experimentsd. both observations and controlled experiments
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.
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
