Calculate the t value (a test statistic) using this formula: Example: Calculating the t value. The weight and length of 10 newborns has a Pearson correlation coefficient of .47. Since we know that n = 10 and r = .47, we can calculate the t value: In correlational research, you investigate whether changes in one variable are associated with changes in other variables. After data collection, you can visualize your data with a scatterplot by plotting one variable on the x-axis and the other on the y-axis. It doesn’t matter which variable you place on either … See more The value of the correlation coefficient always ranges between 1 and -1, and you treat it as a general indicator of the strength of the … See more The correlation coefficient tells you how closely your data fit on a line. If you have a linear relationship, you’ll draw a straight line of best fit that takes all of your data points into account on a scatter plot.
