Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...

Please read the case below. Smyrna University is a private university which is based in İzmir. Smyrna University has gained an excellent reputation for its post-graduate courses, and thus the University has attracted a large number of students who are interested in postgraduate studies and located in Southern and North-Western parts of Turkey. The fees paid by these students make an important contribution to the University’s annual budgeted income. To support the recruitment of students from North-Western and Southern Turkey, the University has established a small department to promote its courses and to liaise with education institutions in Southern and North-Western cities. However, this year there has been a noticeable reduction in the number of applications from Southern and North-Western parts of Turkey. The University authorities are unsure if this is because of the global economic downturn, or if there are other factors causing this reduction. They have decided to conduct…

Cregg Hart is manufacturing manager for Larabee Engineering, a locomotive engine and rail car manufacturer. The company has been very successful in recent years, and in July 2016 signed two major contracts totaling nearly $200 million. A key to the company’s success has been its focus on quality. Customers from around the world have been very pleased with the attention to detail put forth by Larabee Engineering. One of the things Cregg has been adamant about is that Larabee Engineering’s suppliers also provide high quality. As a result, when the company finds good suppliers, it stays with them and tries to establish a long-term relationship. However, Cregg must also factor in the costs of parts and materials and has instructed his purchasing staff to be on the lookout for “better deals.” Recently, Sheryl Carleson, purchasing manager, identified a new rivet supplier in Europe that claims its rivets are as good or better quality than the current supplier’s but at a much lower cost. One…
