The P value is a quantitative expression of the probability that the results of another experiment of the same size and structure will DEVIATE FROM EXPECTED RESULTS AS MUCH AS OR MORE THAN BY CHANCE. The greater the difference between observed and expected results of an experiment,_________ .
A) the lower the ç2 value and the lower the P value
B) the lower the ç2 value and the greater the P value
C) the greater the ç2 value; but the P value is unaffected
D) the greater the ç2 value and the greater the P value
E) the greater the ç2 value and the lower the P value

The greater the difference between observed and expected results, the greater the chi-square (ç2) value, indicating a stronger deviation from what was expected. A higher ç2 value typically results in a lower P value, suggesting that the observed results are less likely to have occurred by chance alone.
