Analyzing Cross-sectional Data and Correlation and Regression Essay

Analyzing Cross-sectional Data and Correlation and Regression - Essay Example All this ratings indicated the level of customer satisfaction regarding our services. The rating according to our instructors indicated that out of 100 hundred participants 12 rated the services as bad, 35 of them rated the services as neither bad or good, 39 rated the services as good and only 14 of them rated our services as very good, the majority therefore rated our services good. This can be graphically represented as follows As graphically shown the mode is good, the graph is negatively skewed or skewed to the left meaning that the majority of the outcomes or observations are on the left of the graph, another notable observation is that none of the participants rated our instructors as very bad. Our services were also rated through the quality of equipments used, out of 100 participants 6 of them rated the quality of equipments as very bad, 25 of them rated the equipments as bad, 33 of them rated the equipments as neither bad nor good, 27 of them rated the equipments as good and only 9 rated the equipments as very good. Therefore the mode or the majority of the participants did not rate our services as bad or good regarding the quality of equipments, the mean of this observation was 3.08 and the standard error was 0.106059, the median and the mode were both 3, the results can be graphically represented as follows: According to the participants our services were also rated according to the range of facilities av... Therefore the mode or the majority of the participants did not rate our services as bad or good regarding the quality of equipments, the mean of this observation was 3.08 and the standard error was 0.106059, the median and the mode were both 3, the results can be graphically represented as follows: quality of any equipment used Frequency Very bad 6 Bad 25 Neither bad nor good 33 Good 27 Very Good 9 0 We can construct a 95% confidence interval as follows P(X - T Sx X + T Sx) = 95% P ((3.08 - 0.172572 (0.106059)) (3.08 + 0.172572(0.106059)) = 95% P ((3.0617) (3.183)) = 95% According to the participants our services were also rated according to the range of facilities available, out of 100 participants only one rated the range of facilities available as very bad, 6 rated the facilities as bad, 20 as neither good or bad and 38 rated the facilities as good, the rest rated them as very good. Therefore according to the rating of the range of facilities we offer, 73 participants rated them as good or very good. This is graphically shown below: The range of facilities available Frequency Very bad 1 Bad 6 Neither bad nor good 20 Good 38 Very Good 35 The mean was 4 and this shows that the average rated the range of equipments available as good; the mode was 4 which indicate that the majority of the participants rated the equipments as good. In the case where the mode, the median and mean are equal, the distribution assumes an asymmetric or bell shape where both deviations from the mean are identical, the negative value of skew ness indicates that the distribution is skewed to the left, the standard error of this observation was 0.094281 and

Dimensions of organisation structure & Technology Research Paper

Dimensions of organisation structure & Technology - Research Paper Example Nonetheless, Toyota experiences considerable difficulties with delegating its power to national plant branch representatives and managers. As a result, the effectiveness of change management and organizational processes within Toyota has little to do with technologies per se but implies the need to restructure the company’s organizational culture and values from the bottom.

Organizational structure is believed to be one of the key factors of Toyota’s sustained commercial success. Even as its competitors were losing billions because of the recession, Toyota still managed to retain its position of a leader in the global car making industry. Recent advances in technologies contribute to Toyota’s organizational achievements and success. The organizational structure of Toyota is that of innovation, technologies, and change (Leonard 1997). With an emphasis made on just-in-time manufacturing, teamwork, and complex enterprise architectures, Toyota relies â€Å"on a series of interrelated and internally consistent choices that reflect the priorities and trade-offs in its competitive situation and strategy† (Hayes & Pisano 1994, p.18). Technologies predetermine the organiz ational structure and development pathways in Toyota; nonetheless, they do not secure the company from organizational and structural failures. That technologies are at the heart of the company’s organizational structure cannot be denied. Everything within the Toyota Corporation is built on the principles of just-in-time production (JIT). The latter is closely aligned with complex information systems and, simultaneously, guarantees that all elements of the company’s organizational structure operate to deliver raw materials and supplies at the time they are needed and used (Bauer & Erdogan 2009).
