Isaac Inc. began operations in January 2021. For some property sales, Isaac recognizes income in the period of sale for financial reporting purposes. However, for income tax purposes, Isaac recognizes income when it collects cash from the buyer's installment payments. In 2021, Isaac had $680 million in sales of this type. Scheduled collections for these sales are as follows: 2021 $ 77 million 2022 133 million 2023 133 million 2024 167 million 2025 170 million $ 680 million Assume that Isaac has a 25% income tax rate and that there were no other differences in income for financial statement and tax purposes. Ignoring operating expenses, what deferred tax liability would Isaac report in its year-end 2021 balance sheet

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.
