Patterns Quiz #1 Review - STEM Physics

Flashcards covering core vocabulary, definitions, equations, and experimental variables from Patterns Quiz #1 Review in STEM Physics.

Average (Equation)

$$\text{Average} = \frac{\text{Sum of Values}}{\text{\# of Values}}$$

Range (Equation)

$$\text{Range} = \text{Smallest \# Subtracted from largest \#}$$

Uncertainty (Equation)

$$\text{Uncertainty} = \frac{\text{Range}}{2}$$

Scientific Claim

A claim that must be testable by experiment and must have a way to prove it wrong.

Science

Finding and using patterns in nature to predict the future or understand the past.

Accuracy

How correct a measurement is compared to tool.

Precision

The number of digits reported in a measurement ($\text{Precision} = \text{\# of digits reported in a measurement}$).

Independent Variable

The variable we change in an experiment.

Dependent Variable

The variable we measure, which is affected by the independent variable.

Controlled Variable

Things kept the same in the experiment or surrounding environment.

what makes a data set more trustworthy

A data set is considered more trustworthy if it has a lower uncertainty.
