SELECT ALL THAT APPLY. Regression a. examines relationship between ordinal variables. b. is a linear prediction model. c. is bivariate if it involves one independent and one dependent variable. d. is multiple if it involves two or more independent and one dependent variable. 16. SELECT ALL THAT APPLY. In the linear regression equation Y = a + b (X) a. X = the score of the independent variable b. a = the Y-intercept c. b = the slope of the...

Regression and Correlation Analysis Use the dependent variable (labeled Y) and one of the independent variables (labeled X1, X2, and X3) in the data file. Select and use one independent variable throughout this analysis. Use Excel to perform the regression and correlation analysis to answer the following. Generate a scatterplot for the specified dependent variable (Y) and the selected independent variable (X), including the graph of the "best fit" line. Interpret. Determine the equation of the "best fit" line, which...

1. Direct relationship: A relationship between two variables, where a change in one variable results in the same change in the other variable. For example, if one variable is increased, then the other variable will also increase. Indirect relationship: A relationship between two variables, where a change in one variable results in the opposite change in the other variable. For example, if one variable is increased, then the other variable will decrease. a. Considering the terms described above, do the...

Finally, the researcher considers using regression analysis to establish a linear relationship between the two variables – hours worked per week and yearly income. a) What is the dependent variable and independent variable for this analysis? Why? b) Use an appropriate plot to investigate the relationship between the two variables. Display the plot. On the same plot, fit a linear trend line including the equation and the coefficient of determination R2 . c) Estimate a simple linear regression model and...
