It is the proportion of the variance in the response variable that can be explained by the explanatory variable. In this example, 71.99% of the variation in the exam scores can be explained by the number of hours studied. Additional Resources. How to Create a Residual Plot on a TI-84 ...

In Method, select Spearman correlation. Click OK in each dialog box.

the acceptable alpha level of 0.05, meaning the correlation is statistically significant. Four things must be reported to describe a relationship: 1) The strength of the relationship given by the correlation coefficient. 2) The direction of the relationship, which can be positive or negative based on the sign of the correlation coefficient.👍 Thanks for watching!

The viewing rectangle on the TI-83 is 94 pixels by 62 pixels. (A pixel is a picture element.) It is useful when graphing to have a “friendly window” in order to avoid distortion in the graph and to avoid obtaining non-integer values when using the trace function of the TI-83. In fact, q ® (ZoomStat) usually gives a "friendly window".

And then our degrees of freedom, that's our sample size minus one. Our sample size is seven so our degrees of freedom would be six. There we have it. This would be, our p value would be approximately 0.053. Our p value would be approximately 0.053.

The formula to calculate the t-score of a correlation coefficient (r) is: t = r√n-2 / √1-r2. The p-value is calculated as the corresponding two-sided p-value for the t-distribution with n-2 degrees of freedom.
