Explain CHI-SQUARE TEST: Chi (pronounced like “pie” but beginning with a “k”) is a Greek letter, and chi-square is “a statistical method used to test whether the classification of data can be ascribed to chance or to some underlying law.”[websters] The chi-square test “is an analysis technique used to estimate whether two variables in a cross tabulation are correlated.”[shin] A chi-square distribution varies from normal distribution based on the “degrees of freedom” used to calculate it. See also normal distribution and Wikipedia on the chi-squared test and on chi-squared distribution..

- 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 chi-square test explain.
- Manual Cross-Validation:
- Meaning with an algorithm, “the name given to a set of techniques that divide up data into training sets and test sets. The training set is given to the algorithm, along with the correct answers... and chi-square test what is.
- 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 chi-square test 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 chi-square test abbreviation.
