Vocabulary Unit 1 & 2 Review

A measure of the quantity of heat that flows through a material. Materials with low (a)   may be used as insulators. Those with high (b)   may be a heat sink.

A measure to determine precise, reproducible, and consistent results that are produced under consistent conditions is (a)   .

• thermal conductivity
• statistically reliable
• variance
• standard deviation

All the values in a data set that are collected during an observation or experiment are called (a)   .

• population
