Calculate the amount of depreciation to report during the year ended december 31 for equipment that was purchased at a cost of $56,000 on october 1. the equipment has an estimated residual value of $2,000 and an estimated useful life of five years or 20,000 hours. assume the equipment was used for 1,000 hours from october 1 to december 31 and the company uses (a) straight-line, (b) double-declining-balance, or (c) units-of-production depreciation. (do not round intermediate calculations.)

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.
