The owner of a house purchased a new home but decided to keep his old residence for a few months until the real estate market improved. He rented it to a tenant with the understanding that the tenant might have to move out in a few months if the house was sold. The tenant paid the owner the agreed rent of $100 per week every Friday. During the next few months, the owner's business suffered serious setbacks so he decided to sell his new home and move back into his old one. He informed the tenant that he would have to vacate the old home, but the tenant refused to vacate and tendered the $100 rental payment the following Friday, which the owner refused to accept. The owner immediately filed suit to eject the tenant. The jurisdiction requires that a statutory written notice be served on any tenant whose term is for less than month-to-month or is not for a fixed term at least three days prior to commencement of eviction proceedings. No written notice of any kind was given to the tenant. How should the owner characterize the tenant to gain immediate possession of his home

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.
