Hello

  I would be most grateful for some advice on whether or not to accept the p-value obtained from running the chi-square goodness-of-fit test in SPSS when the expected count is less than 5. I am familiar with the golden rule for when to use Fisher's Exact test for cross-tabulated data but what should one do in the one-dimensional case? When the expected count is less than 5, a p-value is generated by SPSS but this is accompanied by a footnote indicating that all expected counts are less than 5 (with no advice as to why this is important to know).

  Many thanks for your interest

  Best wishes

  Margaret
