Measures of Central Tendency Essay Example | Topics and Well Written Essays - 1250 words

Measures of Central Tendency - Essay Example Some books define measures of central tendency as measures of the central position. When applying the use of these measures of central tendency, some measures prove to be more effective and appropriate than others (Sharpe, 10). When applying the measures of central tendency one has to know the appropriate measure to use and under what condition is it suitable to work. There are three measures of central tendency, which includes the mean, mode, and median. Mean is the arithmetic average of a given set of data. Mean is the division of the sum of all available data by the number of all observations that contribute to the total sum of the data. Mean is summarizes the ratio or interval data in situations where the given set of data is symmetrical. The total frequency within each class interval concentrates at the midpoint of a given class interval (Davies, 21). To calculate the mean of a set of variables, one needs to divide the sum of all observations by the total number of the given obs ervations. The reasons for this procedure are that the total value is dependent on two factors that are values of individual observations and the total number of observation. When determining the mean of a given set of data, one has to standardize the simple sum by evenly distributing it across all observations. The formula for calculating mean is; Mean= Total sum/total observations. Mean has several advantages as a measure of central tendency since it takes all values of the observation into account. Also, mean is unique since each set of data has its own unique mean. However, mean is susceptible to influence from other outliners. Unusual values that are numerically large or small in a given set of data can affect the outcome of mean (Davies, 22). Additionally, the mean method is not appropriate when measuring the central position of skewed data. In case of skewed data, the mean losses the ability to show the central position of the data because of the skewness  always drags it f rom the typical value.

Apple Computer and Krispy Kreme Essay Example | Topics and Well Written Essays - 500 words

Apple Computer and Krispy Kreme - Essay Example But Apple Computer is a rather profitable and successful corporation. Its main success is a very high quality of its production, and many customers are devoted to the company and its brand for a very long time. It offers a range of professional software products which are very popular in the world. Apple's CEO Steve Jobs is a successful manager, especially after 1996 when he has returned to the corporation, and the technological potential of Apple and NeXT was put together. He terminated some products, such as Newton and OpenDoc. Under his guidance Apple Computer increased its profitability, although his official salary was $1 per year. The company is increasing its activity by new markets entering, such as music distribution and consumer electronics, and Steve Job's activity as the Apple's CEO is highly estimated by shareholders and consumers. So, if I had large amount of money I would invest Apple Computer as this company has great technological and scientific potential which can b e well realised in the future. Krispy Kreme is one of the biggest doughnut store chains in the world. It was originated in 1933 by Vernon Carver Rudolph, and now the company has about 360 U.S. stores (Krispy Kreme Press Kit). In 1990s Krispy Kreme began its international expansion by opening stores in Canada, Mexico, England and South Korea.
