TI Connect™ CE
Students assess the strength of a linear relationship using a residual plot and calculate the correlation coefficient and coefficient of determination to assess the data set.
Students are given a program that loads four data sets onto their graphing calculators. They are asked to determine if a linear regression model fits each of the data sets.
To asses the fit graphically and numerically, students will create a residual plot and look at the r and r2 values.
Students will transform a data set by calculating the logarithm value of the data, which linearizes the exponential data. They will assess the fit graphically and numerically.
