Observational techniques, typically, place the user in the eventual context in which a system will be operated. In contrast, lab-based techniques rely upon careful control of variables that might otherwise confound experimental results. Lab based studies can be used to make direct and fair comparisons between different systems using statistical measures of significance . In contrast, observational studies provide rich insights into the application of an interactive system but it can be difficult to make such direct comparisons when the experience of interactive with the system can be influenced by a host of factors that are difficult to replicate for each system within the eventual context of use.

Compare multipath routing with flow-based routing?
It is desirable to allow packets with the same source and destination to take more than one possible path. This facility can be used to ease congestion and overcome node failures. To operate such a scheme consistently nodes must maintain routing tables specifying what goes where. The mechanisms for this differ with datagram and virtual circuittransport.In flow-based networking, packets are routed as whole flows, i.e. streams of related packets, rather than as individual packets as in current IP/MPLS networks. The unique level of data obtained in flow-based routing, such as flow length, rate, delay variation and other parameters, enable a number of new network benefits.

What does it mean to say that Kepler's laws are empirical?
His discovery was based on observational evidence rather than theory.
Are evaluations of a particular person behavior belief or concept?
Evaluations of a person's behavior are typically beliefs that are influenced by individual perceptions, values, and experiences. These evaluations are subjective judgments made based on thoughts, feelings, and personal interpretations rather than being objective concepts.
How do scientist use observational research and opinion based research?
surveys
What is observational classification?
Observational classification is a method of categorizing data based on direct observation of the characteristics of the items being classified. This approach involves gathering information through visual inspection or measurement rather than relying on theoretical or abstract criteria. It is commonly used in fields such as biology, anthropology, and environmental science.
What is the difference between observational and theoretical classification?
Observational classification is based on what you see and observe about the thing (maybe during an experiment) While theoretical classification is based on what you are being taught or what you have been taught or what you read about the thing.
What scientist did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.
Is the reasoning of psychiatrists circular?
The reasoning of psychiatrists is based on scientific theories, observations, and evidence rather than circular reasoning. Psychiatrists use diagnostic criteria, patient history, and evaluations to form an understanding of mental health conditions and provide appropriate treatment.
How do weathermen or women know the weather?
