The linear correlation coefficient and the linear regression equation produced from the Excel spreadsheet are f(x) = 1.5607693309x + 55.769550074 with the Pearson ’s r value of .7850471558. With the scatter graph that I have made from the data given‚ I can say that Pearson ’s r in this particular assignment

of Linear Correlation Pearson’s Correlation Coefficient (r) Pearson’s R measures the strength or degree of association between two interval ratio variables ranging from .0 to 1 either positive or negative. It is the square root of correlation determination. The closer the measure is to 1 or -1‚ the stronger the relationship. Thus‚ 80 or 90 in either direction indicates a strong relationship exists. Zero means there is no correlation. Pearson’s R is the most commonly used correlation measure. It

chapter eight SURVEY AND CORRELATIONAL RESEARCH DESIGNS You have probably made or heard the popular comment “Is it just me‚ or [fill in the blank here]?” This question is really a survey that asks others to indicate their level of agreement with some viewpoint—for example‚ “Is it just me‚ or is it hot in here?” or “Is it just me‚ or was this exam difficult?” We largely ask such questions to gauge the opinions of others. Many examples likely occur every day‚ from completing a customer satisfaction
