DATA ANALYSIS RELATED QUESTIONS.
The study \"Determinants of Board Exam Results in Engineering\" specically aims to determine the linear relationship of Board Exam Score {BScore} and Entrance Exam Score in College (EScore). A correlation and regression analyses were used in the study and obtained the following results: Correlation analysis: r= 0.924 Simple Linear Regression: a=25.17 b=0.677 Which of the following best describe the slope of the regression line. Select the correct response, The slope of the regression line suggests that a 1 unit increase in the EScore there is 0.667 unit increase in BScore. The slope of the regression line suggests that a 1 unit increase in the EScore there is 25.17 unit increase in BScore. The slope of the regression line suggests that a 1 unit increase in the BScore there is 0.667 unit increase in EScore. The slope of the regression line suggests that a 1 unit increase in the BScore there is 25.17 unit increase in EScore. In regression analysis, the variable that is being predicted is the Select the correct response: predictor variable response variable intervening variable independent variable If the correlation coefcient is a positive value, then the slope of the regression line must be Select the correct response. negative neither negative nor positive The correlation coefficient is used to determine: Select the correct response: O The difference between the direction y-variable and x-variable The strength of linear relationship between the x and y variables A specific value of the x-variable given a specific value of the y-variable A specific value of the y-variable given a specific value of the x-variable Which of the following values of correlation coefficient r show strong correlation? Select the correct response: 1.0 0.01 -0.91 0.525 The study "Determinants of Board Exam Results in Engineering" specifically aims to determine the linear relationship of Board Exam Score (BScore) and Entrance Exam Score in College (EScore). A correlation and regression analyses were used in the study and obtained the following results: Correlation analysis: = 0.924 Simple Linear Regression: a = 25.17 b = 0.677 hat is the estimate of the equation of the regression line? Select the correct response: BScore(y) = 0.667 + 25.17 EScore(x) EScore(y) = 25.17 + 0.667 B Score(x) . BScore(y) = 25.17 + 0.667 EScore(x)If the correlation coefficient is 0.8, the percentage of variation in the response variable explained by the variation in the explanatory variable is Select the correct response: 80% 0.64% 0.80% 64% Correlation analysis is a measure of causal relationship between two variables.
