WPU essays

WPU essays A University should be a place of delight, of liberty, and of learning How could the Seton Hall University help me achieve intellectual independence and assist me in pursuing a life of ideas? Seton Hall University would allow me to fulfill my perfectionist ideals; I would be able to compete with the best and the brightest. Moreover, the non-academic life within a dynamic campus, and a strong sense of community would enhance the challenging courses that the university has to offer. It is not simple to find a distinctive institution with incredible resources as well as personal attention. With a small faculty-to-student ratio in all classes, I could truly have significant interaction with the professors while simultaneously retaining the knowledge Id be acquiring. The hands-on experience with up-to-date equipment would be like a dream come true as Id encompass myself with ubiquitous, influential technology which is taken for granted by the common person. Taking advantage of the broad spectrum of undergraduate programs, I would improve my ability to think quantitatively, solve complicated problems, and apply my knowledge to the real world. Therefore, I have always been interested in the field of buisness, for it embodies my favorite subjects. As my calculus teacher frantically writes the equations of integrals on the board, I jot down the notes with a clear understanding of what the signs stand for and the logic behind them. Business is a major that is expected to continue experiencing growth, especially strong in areas emphasizing technology. Our society is becoming more technologically driven day by day, and is always on the look-out for expansion and increasing efficiency. By choosing Buisness as a profession, I am able to contribute to the well-being of the society as well as rigorously challenging my intellectual abilities. Although both frustration and jubilation will ensue as I endeavor to find creative solutions to d...

How to Calculate Standard Deviation

How to Calculate Standard Deviation Standard deviation (usually denoted by the lowercase Greek letter ÏÆ') is the average or means of all the averages for multiple sets of data. Standard deviation is an important calculation for math and sciences, particularly for lab reports. Scientists and statisticians use standard deviation to determine how closely sets of data are to the mean of all the sets. Fortunately, its an easy calculation to perform. Many calculators have a standard deviation function, however, you can perform the calculation by hand and should understand how to do it. Different Ways to Calculate Standard Deviation There are two main ways to calculate standard deviation: population standard deviation and sample standard deviation. If you collect data from all members of a population or set, you apply the population standard deviation. If you take data that represents a sample of a larger population, you apply the sample standard deviation formula. The equations/calculations are nearly the same with two exceptions: for the population standard deviation, the variance is divided by the number of data points (N), while for the sample ​standard deviation, its divided by the number of data points minus one (N-1, degrees of freedom). Which Equation Do I Use? In general, if youre analyzing data that represents a larger set, choose the sample standard deviation. If you gather data from every member of a set, choose the population standard deviation. Here are some examples: Population Standard Deviation- Analyzing test scores of a class.Population Standard Deviation- Analyzing the age of respondents on a national census.Sample Standard Deviation- Analyzing the effect of caffeine on reaction time on people ages 18 to 25.Sample Standard Deviation- Analyzing the amount of copper in the public water supply. Calculate the Sample Standard Deviation Here are step-by-step instructions for calculating standard deviation by hand: Calculate the mean or average of each data set. To do this, add up all the numbers in a data set and divide by the total number of pieces of data. For example, if you have four numbers in a data set, divide the sum by four. This is the mean of the data set.Subtract the deviance of each piece of data by subtracting the mean from each number. Note that the variance for each piece of data may be a positive or negative number.Square each of the deviations.Add up all of the squared deviations.Divide this number by one less than the number of items in the data set. For example, if you had four numbers, divide by three.Calculate the square root of the resulting value. This is the sample standard deviation. See a worked example of how to calculate sample variance and sample standard deviation. Calculate the Population Standard Deviation Calculate the mean or average of each data set. Add up all the numbers in a data set and divide by the total number of pieces of data. For example, if you have four numbers in a data set, divide the sum by four. This is the mean of the data set.Subtract the deviance of each piece of data by subtracting the mean from each number. Note that the variance for each piece of data may be a positive or negative number.Square each of the deviations.Add up all of the squared deviations.Divide this value by the number of items in the data set. For example, if you had four numbers, divide by four.Calculate the square root of the resulting value. This is the population standard deviation. See an example worked problem for variance and population standard deviation.
