Neither. It is a test of how well the observed values agree with those predicted by the null hypothesis - whatever that might be.

The Chi-squared statistic can be used to test for association.
For goodness of fit test using Chisquare test, Expected frequency = Total number of observations * theoretical probability specified or Expected frequency = Total number of observations / Number of categories if theoretical frequencies are not given. For contingency tables (test for independence) Expected frequency = (Row total * Column total) / Grand total for each cell

Francis Galton originated the test in 1879.
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.

A paternity test can determine if there is a parent-child relationship between two people. A paternity test would give genetic proof of that relationship.

what is the relationship between chest circumference and lung function test
Identify the variables: Determine the variables involved in the relationship. Establish causation: Determine if changes in one variable directly cause changes in another. Control for confounding variables: Consider and address other factors that may influence the relationship. Establish directionality: Determine the direction of cause and effect between the variables. Test causation: Conduct experiments or analyze data to test and confirm the causal relationship.
A test using relative errors comparing factors in a contingency table to determine if the factors are dependent; the null hypothesis is that the factors are independent.
The relationship between the three concept of test,measurement and evaluation are closely related with evaluation coming first followed by measurement and test.The relationship is such that if the need of evaluation arises,it required measurement which will reguired the used of test
