How to determine the relationship between student's study hour and their grades achieved?How to sketch a scatter plof for the data that given?How to find the equation of the lesst square lines that will enable us to predict a students's grade based on his or her study hour?And how to calculate the coefficent of determination and coefficient of correlation?This question based from chapter simple linear regression..

SURVEY THE RELATIONSHIP BETWEEN STUDENT'S STUDY HOUR AND GRADES ACHIEVE NO. STUDENT'S STUDY HOUR GRADES ACHIEVED 3 - 4 hours 3.00 - 3.99 more than 4 hours 3.00 - 3.99 3 - 4 hours 2.00 - 2.99 3.00 - 3.99 + 2 - 3 hours 1 - 2 hours 2.00 - 2.99 1 - 2 hours 3.00 - 3.99 2 - 3 hours 3.00 - 3.99 less than 1 hour less than 1 hour 3.00 - 3.99 1 - 2 hours 3.00 - 3.99 more than 4 hours 3.00 - 3.99 2 - 3 hours 2.00 - 2.99 3 - 4 hours 3.00 - 3.99 3 - 4 hours 3.00 - 3.99 less than 1 hour 1 - 2 hours 3.00 - 3.99 1 - 2 hours 3.00 - 3.99 2 - 3 hours 3.00 - 3.99 more than 4 hours 3.00 - 3.99 more than 4 hours 3.00 - 3.99 3 - 4 hours 3.00 - 3.99 more than 4 hours 2 - 3 hours 3.00 - 3.99 more than 4 hours 3.00 - 3.99 2 - 3 hours 3.00 - 3.99 2 - 3 hours 2.00 - 2.99 2 - 3 hours 3.00 - 3.99 2 - 3 hours 2.00 - 2.99 3 - 4 hours 3.00 - 3.99 3 - 4 hours 2.00 - 2.99
