Collins Corporation uses a predetermined overhead rate based on direct labor cost to apply manufacturing overhead to jobs. The following information applies to the Collins Corporation for the current year: Direct Labor-Hours: Estimated for the Year 24,000 Actual Hours Worked 19,500 Direct Labor Cost Estimated for the Year 300,000 Actual Cost Incurred 210,000 Manufacturing Overhead Estimated for the Year 240,000 Actual Cost Incurred 185,000 Beginning Balance Ending Balance Raw Materials 14,000 22,000 Work in Process 27,000 9,000 Finished Goods 62,000 77,000 The manufacturing overhead cost for the current year will be: a. $17,000 overallocated. b. $17,000 underallocated. c. $55,000 overallocated. d. $55,000 underallocated.

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.
