Correlation is a measue of how close the line fits the points that you found in your experiment. Anyone can say whether they think the line is a good fit or not, but to measure it exactly, we use the correlation coefficient: R 2. Look at the following two plots. In the first, the line fits very well, and in the second, then line fits very poorly.
2 Answers. , Victim of celery induced tongue-numbness. The tingling in your tongue is an allergic reaction to furanocoumourans, a chemical found in celery. It is a toxic chemical produced by plants as a defense mechanism against insects and animals.
My mom usually used to take me to the doctor, and the doc would give me some kinda medicine(I don't know anything about pharmacy) called glycerine (not sure).I just used to apply that on the numb side of tongue and within like 3-4 days, my tongue would be back on the taste business. hope this helped.
