Science is ....

A field of study that requires certain "laws of nature" to be taken on faith

Both a body of knowledge and an intellectual acidity encompassing observation. description, experimentation, and explanation of natural phenomena

A process that can be applied only within the scientific disciplines, such as biology, chemistry, and physics

The only way to understand the natural world

None of the above are correct.

All the following are elects of biological literacy except:

The ability to use the process of scientific inquiry to think creatively about real-world issues having a biological component

Reading the most important books in biology

The ability to integrate into your decision making a consideration of issues having a biological component

The ability to communicate with others about issues having biological component

All of the above are elects of biological literacy

Superstitions are...

Held bu ,ami humans, but not by any non-human species

Just one of many possible forms of scientific thinking

True beliefs that have yet to be fully understood

Irrational beliefs that action not logically related to a course of events influence its outcome

Proof that the scientific method is not perfect

To be useful, a hypothesis will:

Generate a testable prediction

Lead you to the conclusion you feel confident are true

Establish many overlapping explanations for a phenomenon

Be based on evidence that cannot be falsified by scientific experimentation

Be deduced from a critical experimentation

Which of the following statements is correct?

A hypothesis that does not generate a testable prediction is not useful

Common sense is usually a good substitute for the scientific method when trying to understand the world

The scientific method can be use only to understand scientific phenomena

It is not necessary to make observation as part of the scientific method

All of the above are correct

The placebo effect:

Is the frequently observed phenomenon that people tend to respond favorably to any treatment

Reveals that experimental treatments cannot be proven effective

Reveal that experimental treatments cannot be proven effective

Demonstrate that mot scientific studies cannot be replicated

Is an urban legend

Which of the following correctly describes a double-blind test?

The researchers apply two-layered blindfolds to prevent the subjects from seeing the treatment drug

Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo

The researchers know who is receiving the drug and who is receiving the placebo, but they do not know what the supposed effects of the drug should be.

The researchers do not know who receives the drug or the placebo, but the participants do

None of the above are correct.

In controlled experiments:

One variable is manipulated while others are held constant

All variables are dependent on each other

All variables are independent of each other

All variables are held constant

All critical variables are manipulated

If a researcher uses the same experimental setup as in another study, but with different research subjects, the process is considered:

An independent variable:

Can cause a change in a dependent variable

Is generally less variable than a dependent varible

Is plotted on the y-axis in a line graph

Can be controlled less well than a dependent variable

Statistical methods make it possible to:

Prove that any hypothesis is true

Determine how likely it is that certain results have occurred by chance

Unambiguously learn the truth

Reject any hypothesis

Test non-falsifiable hypothesis

Anecdotal evidence:

Is the basis of scientific thinking

Tends to be more reliable than data based on obserations of large numbers of diverse individuals

Is a necessary part of the scientific method

Is often he only way to prove important casual links between two phenomena

Can seem to reveal links between two phenomena, bit the links do not actually exist

A relationship between phenomena that has been established on the basis of large amounts of observational and experimental data is referred to as:

Which of the following issues would be least helped by application of the scientific method?

Developing more effective high school curricula

Evaluating the relationship between violence I video games and criminal behavior in teens

Determining the most effective safely products of automobiles

Formulating public policy on euthanasia

Comparing the effectiveness of two potential antibiotics

What is the meaning of the statement "Correlation does not imply causation"?

Just because two variables in a similar pattern does not mean that changing one viable causes a change in the other

It is not possible to demonstrate a correlation between two variables

When a change in one variable causes a change in another viable, the two variables are not necessarily related to each other

It is not possible to prove the cause of any natural phenomenon

Just because two variables vary in a similar pattern does not meant hat they have a relationship to each others.
