In a statistical analysis, a variable of special interest, the variation of which we want to explain is called the:
A) independent variable
B) dependent variable
C) specific variable
D) constant
?
Thanks!!
Ans:
Correct option is B:
dependent variable.
Variation of dependent variable(i.e. response variable) is explained by the independent variable(predictor variable).

1. In regression analysis, the Sum of Squares Total (SST) is a. The total variation of the dependent variable b. The total variation of the independent variable c. The variation of the dependent variable that is explained by the regression line d. The variation of the dependent variable that is unexplained by the regression line Question 2 In regression analysis, the Sum of Squares Regression (SSR) is A. The total variation of the dependent variable B. The total variation of the independent variable...
In statistical modeling, regression analysis helps you to: a. None of them b. estimate the relationships between two dependent variables and one independent variable. c. estimate the relationships between a dependent variable and one or more independent variables. d. calculate the exact values for the dependent and independent variables.
When the mean value of the dependent variable is independent of variation in the independent variable, the slope of the regression line is a. zero. b. positive. c. negative. d. infinite.
Regression analysis is used to: A. Predict the value of the dependent variable vased on the value of at least one independent variable B. Explain changes in an independent variable on the dependent variable C. It offers proof of causation D. A & B only E. A, B, & C
We want to investigate the causal relationship between the dependent variable Y and independent variable x. X Y 1 2 2 2 3 4 4 4 5 8 A) Calculate the ?0 hat and ?1 hat (show the steps) B) Calculate SSE, S2, and S C) Calculate the t-statistics for ?1 hat
In a regression analysis, the variable that is used to predict the dependent variable a. is the independent variable b. must have the same units as the variable doing the predicting c. is the dependent variable d. usually is denoted by x
QUESTION 3 Which of the following statements describes why multiple regression is often a superior statistical technique over bivariate regression? If done properly, in multiple regression analysis, you get better estimates of the coefficients than you would in a bivariate regression analysis. If done properly, in multiple regression analysis, you get better estimates of the dependent variable than you would in a bivariate regression analysis. If done properly, in multiple regression analysis, you get an improved R-square and adjusted R-...
Analysis of covariance (ANCOVA) removes the effect of which type of variable before testing whether mean group differences on the dependent variable are statistically significant? A. Independent B. Dummy C. Confounding D. Mediating
Which of the following is a true statement? Regression analysis and ANOVA are similar tools because they both determine if an independent variable has an effect on a quantitative dependent variable, but in ANOVA the independent variable is qualitative and in Regression analysis the independent variable in quantitative. Regression analysis and ANOVA are similar tools because they both determine if a qualitative independent variable has an effect on a quantitative dependent variable. Regression analysis and ANOVA are similar tools because...
We
want to determine the strength of the relationship between the
independent variable "age" and the dependent variable "intelligence
quotient". In our sample, the mean of the variable "age" is equal
to 14, and its variance is equal to 46,4. The mean of the variable
"intelligence quotient" is equal to 102, and its variance is equal
to 0. The list of corresponding data for the two variables is
pictured below.
Determine the value of the correlation coefficient between the
two...
