Regression Analysis - Research Paper Example Introduction In order to check the relationship between benefits and the intrinsic, extrinsic and total job satisfaction, 3 bivariate regressions are run. Using the regression equations the linear relationship between the independent variable (benefit) and the 3 sets of dependent variables (total job satisfaction, intrinsic job satisfaction and extrinsic job satisfaction) is established. Bivariate regression analysis shows how the explanatory power of the independent variable in determining the values of the dependent variable (Malhotra, 543). The results from the regression analysis are explained in details. ... from Excel Regression Statistics Multiple R 0.172306 R Square 0.029689 Adjusted R Square 0.001151 Standard Error 0.352328 Observations 36 ANOVA Â   df SS MS F Significance F Regression 1 0.129141 0.129141 1.040326 0.314948704 Residual 34 4.220582 0.124135 Total 35 4.349722 Â   Â   Â   Â   Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Upper 95.0% Intercept 5.1302975 0.179009596 28.6593 2.1E-25 4.766506281 5.4940888 4.76650628 5.49408881 X Variable 1 0.0376321 0.036895473 1.01996 0.31495 -0.03734857 0.1126127 -0.0373486 0.11261267 Graph Key components of the regression analysis Dependent Variable Slope Y-intercept Equation Intrinsic 0.169682348 4.427844793 Benefits= 4.427844793 + 0.16982348*(Intrinsic) 0.16493309 Extrinsic -0.16220711 6.157338158 Benefits= 6.157338158 -0.16220711*(Extrinsic) 0.287582114 Overall 0.0376321 5.1302975 Benefits= 5.1302975 + 0.0376321*(Overall) 0.0296894 Similarities and Differences Similarity: the intercepts of all the thre e regressions are positive and significant at 5% level of significance (as the p-value for all the 3 regressions are less than 0.05) Dissimilarity: The correlation between benefits-total job satisfaction and benefits-intrinsic job satisfaction is positive (as the slope between them is positive) but the correlation between benefits-extrinsic job satisfaction is negative (as the slope between them is negative) The regression results between benefits-intrinsic job satisfaction and benefits-extrinsic job satisfaction is significant at 5% level of confidence (as the p-value for these two is less than 0.05) but the result of benefit-total job satisfaction came to be insignificant at 5% level of confidence. Correlation coefficients The strongest correlation coefficient is between benefits and intrinsic job

International Activity of TESCO - Case Study Example TESCO opened their first Express store in 1994 and now they have over 500 stores selling a range of up to 7,000 lines including fresh produce, wines and spirits and in-store bakery. .(Tesco Core,2005) Metro (approx. 7,000-15,000 sq ft) TESCO opened their first Metro in 1992,bringing the convenience of TESCO to town and city centre locations. Metros cater for thousands of busy customers each week and offer a tailored range of food lines, including ready-meals and sandwiches. .(Tesco Core,2005) Superstore (approx. 20,000-50,000 sq ft) Tesco began opening superstores in the 1970s and during the 1980s and 1990s built a national network, to which additional are being made every year. They have an ongoing programme of extending and refreshing their superstores to improve the overall experience for customers.

The 100th Extra was opened in 2004 and around twenty new Extras open each year, many from extending existing superstores.(Tesco Core,2005) The TESCO strategy aims for equivalent strength in non-food segment as in its food segment. This has meant that TESCO has been making efforts to offer the same great quality, range, price and service for our customers as they do in our food business. TESCO's widest range of non-food can be seen in Extra stores, including electricals, home entertainment, clothing, health and beauty, stationery, cook shop and soft furnishings, and seasonal goods such as barbecues and garden furniture in the summer. Some of TESCO stores also have opticians and nearly 200 have pharmacies. TESCO's current market share of the nonfood sector is less than 7% and it generates sales in non-food in excess of 6 billion each year in the UK alone. The UK's like-for-like non-food sales growth is currently running at around twice the rate of food. All TESCO stores sell some non-food, with their Superstore and Extra formats offering the biggest choice. By introducing these ranges to more of their
