Explain CORRELATION: “The degree of relative correspondence, as between two sets of data.”[websters] If sales go up when the advertising budget goes up, they correlate. The correlation coefficient is a measure of how closely the two data sets correlate. A correlation coefficient of 1 is a perfect correlation, .9 is a strong correlation, and .2 is a weak correlation. This value can also be negative, as when the incidence of a disease goes down when vaccinations go up. A correlation coefficient of -1 is a perfect negative correlation. Always remember, though, that correlation does not imply causation. See also coefficient.
Different definitions in web development like correlation in Dictionary C.
- Manual Coefficient:
- Meaning algebraic symbol prefixed as a multiplier to a variable or unknown quantity (Ex.: x in x(y + z), 6 in 6ab”[websters] When graphing an equation such as y = 3x + 4, the coefficient of x determines the correlation definition.
- Manual Clustering:
- Meaning algorithm for dividing up data instances into groups—not a predetermined set of groups, which would make this classification, but groups identified by the execution of the algorithm because of correlation explain.
- Manual Continuous Variable:
- Meaning value can be any of an infinite number of values, typically within a particular range. For example, if you can express age or size with a decimal number, then they are continuous variables. In a correlation what is.
- Manual Confidence Interval:
- Meaning around an estimate to indicate margin of error, combined with a probability that a value will fall in that range. The field of statistics offers specific mathematical formulas to calculate confidence correlation meaning.
- Manual Covariance:
- Meaning relationship between two variables whose values are observed at the same time; specifically, the average value of the two variables diminished by the product of their average values.”[websters correlation abbreviation.
