Correlation and Regression Assignment Problem 1. a. Explain which variable you chose as the explanatory variable and discuss why. * The explanatory variable is the height. This is because I am assuming that as height increases‚ the weight will increase as well. So the weight is the dependent variable b. Produce a scatter plot and insert the result here. * Scatter plot c. Find the equation of the regression line‚ Write it in the form of y=a+bx‚ where a is the y-intercept

Correlation analysis: The correlation analysis refers to the techniques used in measuring the closeness of the relationship between the variables. The degree of relationship between the variables under consideration is measured through the correlation analysis. And the measure of correlation called as correlation coefficient or correlation index summarizes in one figure the direction and degree of correlation. Thus correlation is a statistical device which helps us in analyzing the covariation

THE REVENUE SOURCES OF FACEBOOK.COM Facebook Revenues Up to $700 Million in 2009‚ On Track Towards $1.1 Billion in 2010 Facebook is tight-lipped about its revenue numbers‚ which is typical of private companies. The most it has said publicly is that it became “free cash-flow positive” as of last September. At the time‚ we estimated it was set to bring in around $550 million for the year in revenues based on previous reports that we and others had heard‚ and from our own calculations. But how did

Multiple Regression Analysis For hypotheses testing of this study‚ multiple regression analysis was conducted. Some assumptions of the relationship between dependent and independent variables need to be met for performing multiple regression analysis like‚ normality‚ linearity‚ homoscedasticity and multicollinearity (Hair et al.‚ 1998). As mentioned earlier‚ the required assumptions have already been met and multiple regression analysis was appropriate. Usually‚ multiple regression analyses
