# (Solved) Use the “RSQ” command in Excel, or the “corrcoef” command in Matlab to determine if the following measurements are linear

Use the “RSQ” command in Excel, or the “corrcoef” command in Matlab to determine if the following measurements are linear, using a minimum value of 0.95 for R2 in your test for statistical significance. Note that “RSQ” returns the value of R2, while “corrcoef” returns the value of R, which can be used to calculate R2. If these measurements are not linear, remove data points until the correlation coefficient is greater than 0.95.
