I met with Talon Peterson and administered 2 different reading test/tasks. First he completed a post test of the Renaissance Star test. This test is vocabulary and comprehension so the results are a fairly good indicator of overall reading ability. What Star won’t measure is fluency which is a major factor in determining a student’s ability to keep pace with their peers on reading and writing tasks. Results are reported in grade year and month. His scores were as follows: Baseline Testing:

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

you cannot consult the regression R2 because (a) ln(Y) may be negative for 0 < Y < 1. (b) the TSS are not measured in the same units between the two models. (c) the slope no longer indicates the effect of a unit change of X on Y in the log-linear model. (d) the regression R2 can be greater than one in the second model. 1 (v) The exponential function (a) is the inverse of the natural logarithm function. (b) does not play an important role in modeling nonlinear regression functions in econometrics

that dream is out of reach for an increasing number of Americans. Why? It is because there are not nearly enough jobs for everyone. Without a jobs recovery‚ there simply is not going to be a housing recovery. In this report‚ I will perform a regression analysis to determine the effect of the Unemployment Rate (UR) on Total New Houses Sold (TNHS). I expect that there will be a negative relationship between the two variables. In other words‚ as the unemployment rate increases‚ the total number of new

union membership. We will use the technique of linear regression and correlation. Regression analysis in this case should predict the value of the dependent variable (annual wages)‚ using independent variables (gender‚ occupation‚ industry‚ years of education‚ race‚ and years of work experience‚ marital status‚ and union membership). Regression Analysis Based on our initial findings from MegaStat‚ we built the following model for regression (coefficient factors are rounded to the nearest hundredth):
