THE EFFECTS OF HETEROGENEITY OF CONTENT AND GUESSING ON THE ACCURACY OF SCORES ON MULTIPLE-CHOICE TESTS DONALD M. MEDLEY Educational Testing Service Inaccuracy in scores on multiple-choice tests may ...
Turing test, the radiologists were asked to distinguish GAN-generated radiographs from actual images. The mean accuracy of the five radiologists was 66.2%, which was higher than that of random guessing ...
or website guessed about in the experiments) are included in all regressions. Subject fixed effects cannot be included for columns (3)–(5) because empirical accuracy is measured at the subject level ...
of these adverse effects . Results Using Monte Carlo simulations, we show that the modified weights outperform first- and second-order weights in terms of heterogeneity quantification. Modified weights are also shown ...
for others in a dictionary. The pre- and delayed post-tests allowed us to calculate a learning effect in both the guessing and dictionary conditions. We explored whether these two vocabulary learning ...
conditions: with signposts, both signposts and menus, and without any guiding devices, signposts improved sense selection accuracy , though the effect was not statistically significant. They significantly ...
to faces [13,19] (Fig 1), but it is unclear whether the information content is itself distinct between the two. While both the ERP and the raw ECoG potential have previously been used to classify object ...

). Classification accuracy was again consistently better for high vs. low noise correlations (ps < 0.01), and there were main effects of noise correlation magnitude (F1,16 = 18.28, p < 0.001) and bin size (F5,80 ...
with the metric “ accuracy .” The accuracy is defined as the division of all the correct classified simulations by the total number of simulations. For simple guessing , the accuracy value is 50%, so the objective ...
