- Give a plausible example of a three-variable research problem in which partial correlation would be a useful analysis. Define X1, X2, and Y. Make sure that you indicate which of your three variables is the "controlled for" variable ( X2). What results might you expect to obtain for this partial correlation, and how would you interpret your results (e.g., spurious correlation, mediation, moderation, and so on)?A_________exists between two variables when the values of one variable are somehow associated with the values of the other variable. trial difference correlation inferenceThe coefficient of determination of a set of data points is 0.87 and the slope of the regression line is -2.86. Determine the linear correlation coefficient of the data.
- A correlation coefficient close to zero is a strong indicator of a positive linear relationship between two variables.How can Spearman's Rank Correlation or Spearman's Product Moment Correlation Coefficient be applied to a real-life problem?Consider a two-dimensional scatterplot representing the relationship between two continuous variables. If the correlation coefficient is -1, then: a. All points lie in a straight line with a slope of -1. b. All points lie in a straight line with an unknown negative slope. c. All points do not lie in a straight line but the best fitting regression line has a slope of -1 d. There is a strong positive relationship between the two variables.
- Describe the relationship between two variables when the correlation coefficient r is near 0.A correlation coefficient of -0.95 means there is a ____________ between the two variables. Strong positive correlation Weak negative correlation Strong negative correlation No correlationWhat does a correlation coefficient of 2 indicate? There is a weak relationship between the two quantitative variables. It indicates a calculation error, as the correlation coefficient cannot be 2. There is a strong relationship between the two quantitative variables. It indicates a non-linear relationship between the two quantitative variables. There is no linear relationship between the two quantitative variables.
- Compute the value of the correlation coefficient for the data obtained in the study of the number of absences and the final grade of the seven students in the statistics class. Student. Number of absences. Also, find the equation of the regression line for the given data? Student. Number of absences. Final grade% ---------------------------------------------------------------------------- A. 6 82 B 2 86 C. 15 43 D. 9 74 E. 12 58 F 5 90 G 8 78When calculating a correlation coefficient between two continuous variables, the scales on which the variables are measured affect the value of the correlation coefficient. True or FalseTRUE or FALSE.1. If there is a negative correlation between anxiety and performance on complex tasks, then either high level of anxiety causes poor performance on complex tasks or poor performance on complex tasks causes high levels of anxiety. 2. A correlation of 0.29 indicates a weaker linear relationship than a correlation of -0.40. 3. A zero correlation between variables X and Y means that X and Y have no relationship. 4. If there is no relationship between two variables, then the correlation coefficient is 0. 5.
