Scientific Inquiry

What is a scientific theory?

• A hypothesis that has not been tested.

• A well-substantiated explanation of an aspect of the natural world based on evidence.

• An unproven idea that is widely accepted.

• A guess about how things work.

What is a variable in an experiment?

• A variable is a constant factor that does not change during an experiment.

• A variable is any factor that can change in an experiment, affecting the outcome.

• A variable is the final result of an experiment that is measured.

• A variable is a type of equipment used in experiments.

What is an inference?

• A method of collecting data through experiments.

• A conclusion drawn from observations and prior knowledge.

• A type of logical fallacy in reasoning.

• A statement that cannot be proven or disproven.

What is peer review in scientific research?

• A process where researchers publish their work without evaluation

• A method for researchers to evaluate their own work

• The process by which other experts evaluate a researcher's work before it is published.

• A system for funding scientific research projects.

What is a hypothesis?

• A hypothesis is a guess about the outcome of an experiment.

• A hypothesis is a testable prediction about the relationship between variables.

• A hypothesis is a statement that cannot be tested.

• A hypothesis is a conclusion drawn from data.

What is the difference between qualitative and quantitative data?

• Qualitative data involves numerical measurements, while quantitative data describes characteristics or qualities.

• Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

• Qualitative data is always more reliable than quantitative data.

• Quantitative data is subjective, while qualitative data is objective.

What is a control group?

• A group that receives the treatment being tested.

• A standard of comparison in an experiment that is not exposed to the treatment.

• A group that is used to manipulate variables in an experiment.

• A group that is randomly selected from the population.

What is an observation?

• An observation is a guess made without evidence.

• An observation is information gathered using the five senses.

• An observation is a conclusion drawn from assumptions.

• An observation is a statement that cannot be proven.

What is the role of experimentation in scientific inquiry?

• Experimentation is used to test hypotheses and gather data to support or refute them.

• Experimentation is primarily used for making observations without any data collection.

• Experimentation is a method to prove theories without testing them.

• Experimentation is only necessary in the final stages of scientific research.

What is data collection?

• Data collection is the process of gathering and measuring information on variables of interest.

• Data collection is the analysis of data to draw conclusions.

• Data collection is the process of storing data in a database.

• Data collection is the method of deleting unnecessary data.
