Explanation:
In the scientific method, the term measurement refers to a scale, instrument or unit that is applied to an event or object to study it and prove a hypothesis. Additionally, measurements can be of different types as these are consider as quantitative if it deals with numerical information, as qualitative if they deal with patterns that are not expressed by numbers; as reliable if the results found with a measurement is replicable and verifiable and as valid in the case the measure directly addresses or measures the phenomenon, event or object that is being studied. Therefore, a measure that actually measures what it is intended to measure is considered as a valid measurement.

Explanation:
Romantic relationships between partners go through following various stages, relationship transitioned initial attraction to deep bond : 
- Initiation : People just beginning to interact with each other. First impression interaction is very sweet, polite
 - Experimental / Exploratory : They try to understand each other better, start interacting more, more indulgently. Start spending time with each other,  sharing casual information about each other, not too crucial one
 - Intensification : They take initiative to grow relationship further, are aware of each other pros & cons, try to solve issues. 
 - Integration : They are certain of their relationship, seek for commitment towards each other. 
 - Bonding : They give their relationship a recognition, formal name in front of their family, friends.

This outcome would be known as a <u>ceiling effect.</u>
In psychology, the ceiling effect is when a test establishes a range too low for measuring certain variable, that is to say, is when the upper limit (ceiling) of the test is too low, inadequate and not enough for the participants that the test is evaluating. 
In this case, the participants are supposed to respond differently since some played violent video games for 5 minutes and other group played for 25 minutes. Since the outcome was that the majority were rated as "very aggressive", it's an indicator that they weren't tested adequately: the range was low, and therefore, it made it easier for some participants to get the score "very aggressive".
