teststyle = chisq (Default)

Column1 is the UPI.

Column Data Type Description
column1 CHAR First of pair of variables.
column2 CHAR Second of pair of variables.
Chisq FLOAT Chi-Squared statistic.
DF INTEGER Degrees of freedom.
Z FLOAT Z-score.
CramersV FLOAT Cramer's V.
PhiCoeff FLOAT Phi coefficient.
LlhChiSq FLOAT Likelihood ratio Chi-Squared statistic.
ContAdjChiSq FLOAT Continuity-adjusted Chi-Squared statistic.
ContinCoeff FLOAT Contingency coefficient.
ChiPValue FLOAT Probability associated with Chi-Squared statistic.
ChiPText CHAR Text description if probability is outside table range.
ChiCallP_0.05 CHAR Chi-Squared result:
  • a=accept null hypothesis

    (not significantly different)

  • p=reject null hypothesis (positive)

    (significantly different)

  • n=reject null hypothesis (negative)

Example

The following tables show how the Chi-Squared test was computed on all combinations of pairs of the two sets of variables. Results are sorted by column1 and column2. The tests show that probabilities observed are the same for three pairs of variables and different for three other pairs.
