1. T/F and explain: In simple linear regression there can be only one independent and one dependent variable, but in multiple regression there can be more than one independent variable and more than one dependent variable.

.2. From regression, using you own words, define the Error Term.

3. Why is it important to check for correlation between independent variables in multiple regression?

4. Assume two of your right hand side variables are correlated. What techniques are available to you to correct this problem?

a.

b.

c.

5. Assume your Alpha value is .05. After running a regression with 4 independent variables you find the following P values:

Var1 P=7.0 Var2 P=0.7 Var3 P=0.07 Var4 P=0.007

What is the appropriate next step?

Say your supervisor performs a regression and later find that one of your independent variables (X1) is correlated with another variable that you did not include the regression (X2), and this other variable might better explain the variance in the dependent variable (Y). Explain what is likely to happen if your supervisor conducts another regression with both of these independent variables included in the model.

A regression analysis is a statistical assessment of the association between two variables, one of which is dependent and the other, independent. The dependent variable is y and the independent variable is x. Regression analysis is used to find the relationships between these variables. Variables within a regression analysis can be negatively correlated or positively correlated. A situation in which one could model a regression analysis could be the association of hours studied and a grade on a test. The...

Many times, multiple variables can be correlated, affecting the outcome of the dependent variable. Describe, in detail, the process for determining if more than one variable contributes to the outcome of a single dependent variable. How accurate is a regression analysis and how do you know? What attributes of the analysis will determine whether the analysis is accurate and to what extent? Can inaccurate regression analyses be used to an analyzer’s benefit? Explain in detail

What socio-economic variables could serve as Independent variables when conducting a multiple linear Regression with the dependent variable "Happiness Index"? (I already have GDP/capita, divorce rate, unemployment rate, urbanization rate) Maybe you also can come up with an "interesting" one where there is not yet so much Research on a potential correlation with Happiness.

Below are the define variables: 1. Dependent variable: defects 2. Independent variables: testing effort, development effort, test cases, code size, number of developers. We want to predict number of defect in order to minimize testing efforts prior to testing. Assume we have used multiple regression and have predicted number of defects. Question: How can we prove the defects we have predicted will minimize testing efforts?

RESEARCH QUESTION 1: Are amount of school loan debt, hours of sleep per night, age, time spent in community service, and stress related to each other? These variables are in SPSS as:debt, sleep, age, service, and stress. Each of these variables was measured so that a bigger value equals more (ex. 1 = no stress, 7 = high stress). Based on your investigation of how these variables relate to each other in SPSS, select the variables that are significantly correlated...
