Using general loglinear regression (Poisson model) under the hypothesis that these two variables are independent of each other, our analysis showed that there is a systematic relationship (significance probability is 0.0504) between source of selected terms and answer accuracy.
the two-tailed t test (df =222) produces a p-value of less than .01% for the comparison of the expected and selected proportions of a) human terms and head sorted terms and b) human terms and technical terms.
