9: Many sciences rely on observation instead of (or in addition to) designed experiments. Compare the data quality issues involved in observational science with those of experimental science and data mining.
For the answer:
A) List 2 drawbacks involved in observational science. Explain each drawback with 1 sentence.
B) List 2 drawbacks involved in experimental science. Explain each drawback with 1 sentence.
C) Explain in less than 4 sentences why would you prefer one approach over the other (observational and experimental approach).
10: Discuss the difference between the precision of a measurement and the terms single and double precision, as they are used in computer science, typically to represent floating-point numbers that require 32 and 64 bits, respectively.
Some material on single and double: https://www.mathworks.com/help/matlab/matlab_prog/floating-point-numbers.html
For the answer:
A) Define single precision in terms of bits in a memory.
1) What each bit represents
2) What is the decimal maximum value a single precision can represent?
B) How much more precise is a double precision format?
C) Writ one sentence on why you would use double over single?
- This exercise compares and contrasts some similarity and distance measures.
For the answer:
A) For binary data, the L1 distance corresponds to the Hamming distance; that is, the number of bits that are different between two binary vectors. The Jaccard similarity is a measure of the similarity between two binary vectors.
x = 0101010001
y = 0100011000
1) Compute the Hamming distance between x and y.
2) Compute the Jaccard similarity between x and y.
B) Explain in one sentence, which approach, Jaccard or Hamming distance, is more similar to the Simple Matching Coefficient.
C) Explain in one sentence, which approach is more similar to the cosine measure?
D) If you are comparing how similar two organisms of different species are in terms of the number of genes they share.
1) Explain, which measure, Hamming or Jaccard, would be more appropriate for comparing the genetic makeup of two organisms. (Assume that each animal is represented as a binary vector, where each attribute is 1 if a particular gene is present in the organism and 0 otherwise.)
2) If you wanted to compare the genetic makeup of two organisms of the same species, e.g., two human beings, explain in one sentence. which you would use the Hamming distance, the Jaccard coefficient, or a different measure.
Correspondence measure Communication involves 75% of each working day and should be possible verbally or non verbally. All together for an association to succeed, it is important to demonstrate the accomplishment of correspondence between the staff. When the goal is accomplished, correspondence is viewed as effective. Whether or not it is a help for notice, influence, or different purposes, all correspondence has a reason; correspondence is an association of all divisions inside the association. Successful and compelling correspondence inside the association emerges from the usage of the correspondence cycle. In the event that all the individuals from the association follow the correspondence cycle, they improve their relational abilities and escape from different Nonverbal Communication Non-verbal correspondence Any communication includes two principle components of how individuals are seen: words, or articulations and non-verbal words, articulations, motions, language pitch, and other Position. Numerous individuals feel that the primary messages are their words, yet that is really their nonverbal hints. The speculation of this examination paper is that outward appearances legitimately influence human observation. This speculation is affirmed by short writing search. Nonverbal correspondence is normally more important than verbal correspondence Nonverbal correspondence is unimportant than verbal correspondence Nonverbal correspondence is regularly more uncertain than verbal correspondence. Non-verbal data about our own introduction, attire style, and our personality will be sent in situations, for example, residences, lofts, vehicles or workplaces. Dissect some non verbal signs sent by your own introduction or condition. How would they say what your identity is? Do they make the impression you want? What is nonverbal correspondence? Nonverbal correspondence is all messages sent notwithstanding correspondence words. These messages are, for instance, discourse, face message, eye to eye connection, spatial message, and so on. Nonverbal correspondence normally passes on more importance than verbal correspondence. As indicated by Dr. Albert Melavian, nonverbal correspondence represents 93% of every day correspondence. This measurement shows that nonverbal correspondence is significant in our every day life. At the point when we talk, we normally don't simply express in words, messages other than words pass on more data than words. In this manner, we can finish up both head and nonverbal work in return. The accompanying papers depict the significance of occurrence based nonverbal correspondence and the sorts of nonverbal communication.obstacles. Individuals who comprehend the correspondence cycle have developed into a more successful communicator and viable communicators are demonstrated to be bound to succeed. The correspondence cycle is a manual for successful correspondence. Through the correspondence cycle, senders and beneficiaries share a typical significance. Individuals who follow the correspondence cycle have the chance to work all the more productively in each part of occupation. Powerful correspondence is valuable for comprehension. The correspondence cycle comprises of four primary segments. These parts incorporate coding, transmission medium, interpreting and input. There are two different factors in this cycle show up as senders and beneficiaries. The correspondence cycle begins from the sender side and finishes on the beneficiary side. We should perceive what we have realized. The correspondence cycle is a stage to make correspondence fruitful. The segments of the correspondence cycle incorporate sender, message code, choice of correspondence channel, gathering of message by beneficiary, and deciphering of message.>GET ANSWER
