Driving 15000 miles, split between city and highway, will require (roughly) 500 gallons in a Corolla but only 325 gallons for a Prius. Say that the government introduces a plan to improve fuel economy in the US as much as if people were moving from Corollas to Priuses. If 10% of all cars (i. e. 24 million of the 240 million out there in 2011) upgrade in this way, and each person drives 15000 miles per year as described above (and all gas comes from the amount imported), then by what percent would US imports of petroleum decrease

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e. g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
