correlation (redirected from Pearson's correlation coefficient)

correlation /cor·re·la·tion/ (kor″ĕ-la´shun) in statistics, the degree and direction of association of variable phenomena; how well one can be predicted from the other.

correlation

[kôr′əlā′shən]

Etymology: L, com + relatio, a carrying back

(in statistics) a relationship between variables that may be negative (inverse), positive, or curvilinear. Correlation is measured and expressed by using numeric scales.

correlation,

n a statistical procedure used to determine the degree to which two (or more) variables vary together. Correlation does not suggest a cause-effect relationship but only the degree of parallelism or concomitance between the variables, the cause of which may be unknown. The
Pearson product-moment correlation (r) is the most frequently used, and this coefficient is used unless another is specified.

correlation, coefficient number

n the result of statistical computation that indicates the strength of the tendency of two or more variables to vary concomitantly. The coefficient is expressed in fractions (that is, r = 80), ranging from 21 to 11, and indicates the magnitude of the relationship between the variables. Perfect direct correspondence is expressed by 11; perfect inverse correspondence by 21; complete lack of correspondence by 0. Fractional values are not read as percents.

correlation, linear,

n a correlation in which the regression line, the line that best describes the relationship between the two variables, is a straight line, so that for any increase in the magnitude of one variable there will be a proportional change in the magnitude of the other variable.

correlation, multiple,

n a complex correlation procedure in which scores on two or more variables are combined to predict scores on another variable, called the
dependent variable.

correlation

Statistics The degree to which an event, factor, phenomenon, or variable is associated with, related to, or can be predicted from another; the degree to which a linear relationship exists between variables, measured by a correlation coefficient.

Patient discussion about Pearson's correlation coefficient.

Q. I have chronic hayfever problems in the mornings for the first hour.Seems to be a correlation with dairy produ I also got asthma 8 years ago at age 69, after having 2 pet cats. It is controlled with 2 puffs of Symbicord daily, am & pm. Anyone managed a complete cure?

A. Allergies/hay fever/asthma-No CURE as of now,controlled by medication. ther also are two types of asthma-cardiac asthma usually you find in older people,next time you talk to your DR-ask him-sometimes DRs do not want to upsat there patients--asthma attacks can happen from food allergies,see what he/she saids about it----good luck-mrfoot56

Q. What correlation is there between Diet and Fitness? do i attain those two in a similar way? do i have to attain one in order to complete/gain the other ?

A. agree with dominicus. if you want to be healthier, you should keep your eye on what you eat and how often/how regular you do the exercise.
the result will be best if you can combine those two in balance portion and in healthy and wise manner.

Good luck, and stay healthy always..
