Every sample has some variation in it (unless all the values are identical, and that's unlikely to happen). The total variation is made up of two parts, the part that can be explained by the regression equation and the part that can't be explained by the regression equation
Well, the ratio of the explained variation to the total variation is a measure of how good the regression line is. If the regression line passed through every point on the scatter plot exactly, it would be able to explain all of the variation. The further the line is from the points, the less it is able to explain.
a) Adjusted R2: This is an adjustment for the fact that when one has a large number of independent variables; it is possible that R2 will become artificially high because some independent chance variations explain small parts of the variance of the dependence. The contrary would make it always 1.0. The adjustment to the formula arbitrarily lowers R2 as the numbers of independent variables increases. When used for few independent variables, R2 and adjusted R2 would always be close.
b) The Students Test of the Null Hypothesis (t-statistics): This is used to assess the significance of individual “b†coefficients, specifically testing the null hypothesis that the regression coefficient is zero. A common rule of thumb is to drop from the equation all variables not significant at the 0.05 level or better.
The importance of regression was stressed by Oghene et al (2006) as;
i. How well do the regressors, taken together to explain the variation in the dependent variable? This is assessed by the value of R2.
ii. Are the regressors, taken together, significantly associated with the dependent variables? This is assessed by the statistic F in the analysis part of the regression output.
iii. What relationship does each regressors have with the dependent variables when all other regressors are held constant? This is answered by looking at the regression coefficient.
iv. Which independent variable has the most effect on the dependent variables?
v. Are the relationships of each regressor with the dependent variables statistically significant with all other regressors taken into account? This is answered by looking at the t values in the table of regression coefficient.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis study explains the effects of financial crisis on crude oil prices, stock prices and inflation rates in Nigeria and the global markets. Data were obtained from major players in the financial and oil sectors of the economy. They were analyzed using statistical packages. The results showed that crude oil and stock prices were both increasing before the crisis and decreased during and after the crisis. It was also observed that the inflation rate was increasing. ...

CHAPTER TWO - [ Total Page(s): 4 ]CHAPTER TWOLITERATURE REVIEWINTRODUCTIONThis chapter is a review of the literature encountered during the course of this study. It aims to set out the foundation upon which the author builds and addresses the lack of specific literature on financial crisis by building bridges between the literature that is available in the field of inflation, stock market and the literature concerning crude oil prices.The chapter also evaluates the current information on the state of the global financial crisis. ...

CHAPTER FOUR - [ Total Page(s): 6 ]The simple hypothesis that we will be testing under this sector is that there is no significant difference between the average prices of stock before the crisis and during the crisis. The above table shows that it is only Intercontinental Bank that there do not exist a significant difference “before crisis prices and during crisis prices. In the other banks there exists a significant difference in the price of the stock.PETROLEUM (MARKET) SECTORIn this sector there was no significant diffe ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 2 ]CHAPTER FIVESUMMARY, CONCLUSION AND RECOMMENDATIONSSUMMARYChapter one saw us introducing the concept of global financial crisis. Attempts are made to give a background of global financial crisis, viz a viz the Nigeria situation. Nigeria is a part and parcel of the committee of nations low vulnerable. It was observed that Nigeria economy to global financial crisis and what have been the effects of the inflation, the magnitude and trend on the various sectors.Also, the objectives for this research ...
