• a measurement is a quantity that has both a ____ and a ____.

Explanation:

These are key terminology fill-in-the-blanks for introductory chemistry experimental and scientific method concepts, based on standard scientific process definitions.

Answer:

Module 0: Intro. to Chemistry and Measurement

• The variable that is measured during the experiment is the dependent variable. ...THEN (this) WILL HAPPEN.
• Control variables or groups are standards used for comparison in the experiment.
• Sample groups are often split into an experimental group and a control group.
• Data and Conclusions:
• At the end of an experiment, it is important to analyze the data in as many ways as possible. (calculations, graphs, etc.)
• A conclusion is a judgment based on the information obtained from the experiment.
• Communicating Results:
• For the results of an experiment to be accepted, the experiment must produce the same/consistent result no matter how many times it is repeated or by whom.
• This is why scientists are expected to publish a description of their procedures along with their results for peer review.
• PEER REVIEW is one of the most important parts of science!!!

Scientific Theory

• Hypothesis to Theory:
• Once a hypothesis meets the test of repeated experiments/consistent evidence, it may be raised to a higher level of ideas. It may become a theory.
• A theory is a well-tested explanation for a broad set of observations.

Bias in Experiments

• Scientific Bias:
• Bias is any tendency which prevents unprejudiced consideration of a question.
• Bias occurs in research when systematic error is introduced into sampling or testing by selecting or encouraging one outcome or answer over others.
• Types of scientific bias include:
• Design of experiment
• Omission of undesirable data
• Inclusive of desirable data
• Confirmation bias (or "Interpretation bias")

Measurement

• What is a Measurement?:
• A measurement is a quantity that has both a number/magnitude and a unit.
