What is the primary goal of observation in scientific inquiry?

  1. To gather data and evidence

  2. To formulate hypotheses

  3. To test hypotheses

  4. To interpret results


Correct Option: A
Explanation:

The primary goal of observation in scientific inquiry is to gather data and evidence that can be used to support or refute hypotheses.

Which of the following is NOT a characteristic of good observation?

  1. Objectivity

  2. Accuracy

  3. Selectivity

  4. Reliability


Correct Option: C
Explanation:

Selectivity is not a characteristic of good observation because it involves choosing only the data that supports a particular hypothesis, which can lead to biased results.

What is the difference between observation and inference?

  1. Observation is based on direct experience, while inference is based on indirect evidence.

  2. Observation is subjective, while inference is objective.

  3. Observation is qualitative, while inference is quantitative.

  4. Observation is concerned with facts, while inference is concerned with theories.


Correct Option: A
Explanation:

Observation involves directly experiencing and recording data, while inference involves drawing conclusions based on the observed data.

What is the role of experimentation in scientific inquiry?

  1. To test hypotheses

  2. To gather data and evidence

  3. To formulate hypotheses

  4. To interpret results


Correct Option: A
Explanation:

The primary role of experimentation in scientific inquiry is to test hypotheses by manipulating variables and observing the effects of those manipulations.

Which of the following is NOT a type of experiment?

  1. Controlled experiment

  2. Natural experiment

  3. Observational study

  4. Thought experiment


Correct Option: C
Explanation:

Observational studies are not experiments because they do not involve manipulating variables to test hypotheses.

What is the purpose of a controlled experiment?

  1. To eliminate confounding variables

  2. To test multiple hypotheses simultaneously

  3. To gather data and evidence

  4. To interpret results


Correct Option: A
Explanation:

The purpose of a controlled experiment is to eliminate confounding variables that could potentially影響 the results of the experiment.

What is the difference between a dependent variable and an independent variable?

  1. The dependent variable is the variable that is being measured, while the independent variable is the variable that is being manipulated.

  2. The dependent variable is the variable that is being manipulated, while the independent variable is the variable that is being measured.

  3. The dependent variable is the variable that is being controlled, while the independent variable is the variable that is being changed.

  4. The dependent variable is the variable that is being changed, while the independent variable is the variable that is being controlled.


Correct Option: A
Explanation:

In an experiment, the independent variable is the one that is manipulated by the experimenter, while the dependent variable is the one that is measured to see how it is affected by the manipulation.

What is the importance of replication in scientific research?

  1. It helps to ensure the reliability of the results.

  2. It helps to identify confounding variables.

  3. It helps to formulate new hypotheses.

  4. It helps to interpret results.


Correct Option: A
Explanation:

Replication is important in scientific research because it helps to ensure that the results of a study are reliable and not due to chance or other factors.

What is the relationship between observation and theory in scientific inquiry?

  1. Observation leads to theory.

  2. Theory leads to observation.

  3. Observation and theory are independent of each other.

  4. Observation and theory are mutually supportive.


Correct Option: D
Explanation:

Observation and theory are mutually supportive in scientific inquiry, as observations can lead to the development of theories, and theories can guide further observations.

Which of the following is NOT a limitation of observation in scientific inquiry?

  1. It can be subjective.

  2. It can be inaccurate.

  3. It can be selective.

  4. It can be used to test hypotheses.


Correct Option: D
Explanation:

Observation cannot be used to test hypotheses directly, as it involves gathering data and evidence, not manipulating variables.

What is the role of interpretation in scientific inquiry?

  1. To draw conclusions from data

  2. To formulate hypotheses

  3. To design experiments

  4. To gather data


Correct Option: A
Explanation:

Interpretation plays a crucial role in scientific inquiry, as it involves drawing conclusions from the data gathered through observation and experimentation.

Which of the following is NOT a type of scientific observation?

  1. Direct observation

  2. Indirect observation

  3. Qualitative observation

  4. Quantitative observation


Correct Option: B
Explanation:

Indirect observation is not a type of scientific observation because it involves inferring information about an object or phenomenon based on other observations or evidence.

What is the importance of controlling variables in an experiment?

  1. To eliminate confounding variables

  2. To ensure the accuracy of the results

  3. To increase the sample size

  4. To reduce the cost of the experiment


Correct Option: A
Explanation:

Controlling variables in an experiment is important to eliminate confounding variables that could potentially影響 the results of the experiment.

Which of the following is NOT a characteristic of a good experiment?

  1. Validity

  2. Reliability

  3. Generalizability

  4. Bias


Correct Option: D
Explanation:

Bias is not a characteristic of a good experiment because it can lead to inaccurate or misleading results.

What is the purpose of a hypothesis in scientific inquiry?

  1. To explain a phenomenon

  2. To predict a phenomenon

  3. To test a phenomenon

  4. To interpret a phenomenon


Correct Option: C
Explanation:

The primary purpose of a hypothesis in scientific inquiry is to test a phenomenon by making predictions that can be tested through observation and experimentation.
