Intro to Chemistry- Final Exam
Review
Precision - ✔✔ correct answer how close measurements are to each other
Accuracy - ✔✔ correct answer closeness of a measurement to the actual value
observation - ✔✔ correct answer info that you obtain through senses
inference - ✔✔ correct answer conclusions drawn based on observations
directly proportional - ✔✔ correct answer if one variable goes up and the other variable goes up
inversely - ✔✔ correct answer if one variable goes up and the other variable goes down
manipulated variable - ✔✔ correct answer x-axis
responding variable - ✔✔ correct answer y-axis
qualitative data - ✔✔ correct answer words, such as hot or heavy, for data
quantitative data - ✔✔ correct answer numbers, such as km/hour, for data
scientific fact - ✔✔ correct answer statement that summarizes a pattern found in nature
scientific theory - ✔✔ correct answer well-tested explanation for a set of observations or
experimental results
scientific model - ✔✔ correct answer representation of an idea, an object, or even a process or a
system that is used to describe and explain phenomena that cannot be explained directly.
ex: model of the motions of the sun, moon, and earth
constant - ✔✔ correct answer factor that does not change when other variables change.
