- 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 investigationWhich of the following is used when testing a prediction?a. observationsb. inductive reasoningc. controlled experimentsd. both observations and controlled experiments3. A hypothesis must contain which of the following variables? tablvona fegnibenne variables 29 nozzl) a. only the dependent or responding variable b. only the dependent or manipulated variable OW shawens snoted vijuters dilida way Jer usy bayni and to 16 sk 3 miuton nsmngleza es batalo C. both the manipulated and responding variable d. both the manipulated and responding variables, as well as all the controlled variables
- What makes Science different from other subjects? O a. Objective O b. Does not claim to be right or confer value O c. Falsifiable O d. Scientists are more observant than others. De. It is the only field that uses deductive reasoning. f. Only has theories that explain what is observed ост 28 MacB esc 80 F1 F2 F3 F4 F5 ! # 24 1 3 Q W R T tab A D F caps lock X C V shift fn くO ピIdeally, an experimental group differs from a control group (a) only with respect to the hypothesis being tested (b) because its subjects are more reliable (c) in that it is less subject to bias (d) in that it is less vulnerable to sampling error (e) only with respect to the variable being studiedWhen 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.
- What is one advantage of manipulative field experiments? а. Complete control of environmental variation O b. Easier integration with theory compared to other approaches Ос. Allows comparison of treatments in natural setting O d. None of the above O e. All of the aboveThe '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 these statements are true about predictions and hypotheses? (4 are true) □ If the results of the experiment are NOT consistent with a given prediction then that hypothesis is false. O Hypotheses and predotions are the same as theories. A predictions is a possible explanations to explain the initial observation. Predictions and hypotheses are the same thing. Predictions are usually written as if/then statements. "If I do this, then that will happen." O The prediction step comes before the hypothesis. Hypotheses are usually written as if/then statements. "If I do this, then that will happen." A hypothesis is a possible explanations to explain the initial observation. O The prediction step comes after the hypothesis.
- Nature of Science & Data Analysis Review Name Period Match the following terms with their definitions: 1. NOT an educated guess, rather a possible explanation to observations. These should be written as an If/ Then statement. 2. A. observation B. inference C. controlled Using one or more of the senses to gather information. 3. The variables that stay the same in the control group and the experimental group. 4. variables D. experimental A logical interpretation of the data based on prior knowledge and experience The manipulated variable. This is what I (the scientist) change in an experiment. 6. group E. control group F. theory G. law The responding variable. This is what is measured in an experiment. 7. A way of doing science. There are steps that include observation, H. scientific question, hypothesis, experiment, analysis, conclusion. These steps are not always completed in the same order. 8. It describes the process of HOW something happens 9. method I. independent variable A well…In order to minimize systematic error in a study, researchers should: *C IS NOT THE CORRECT OPTION SO I DONT KNOW WHAT ELSE IT COULD BE* A. Use rigorous study methods B. Recruit a large number of people to the study C. Select study participants based on disease status d. A and B e. None of the aboveII.) Answer as comprehensively and as briefly as you can. When is a hypothesis accepted? Why is a variable included in an experiment? Discuss the importance of a control in interpreting the results of an experiment? What are the reasons for conducting an experiment? Differentiate discovery-based from hypothesis-driven science?
