The research aims to determine the impact of different sample size in honesty discriminatory personal scale and shape of frequency distribution of grades among the students of the fourth stage in the colleges of physical education at the University of the Middle Euphrates / Iraq: (Kufa, Karbala, Babil, Qadisiyah, Muthanna). . To achieve this goal, the researchers compared the samples after Tksmiha to five volumes, and the number of members of these volumes, respectively: (50.10015 million, 200 250 300), pulled samples - in every stage of the selection - randomly. . The researchers used a descriptive approach Bnmth Ashei, such as scale (Freiburg personality) the main tool for the study. . After verifying the validity of the scale of the application, proceeded researchers applied to samples sizes five, and analyzed the answers, only honesty discriminatory using t-test for independent samples, between the two groups extremes in the total score and by (27%), in each group, a difference in the level of signify honesty discriminatory between the sizes of the samples. To learn the form of frequency distribution of degrees each sample researchers used test (chi square), that there is a difference in the levels of statistical significance between the sizes of the samples. .
In light of these results the researchers found that the greater the size of the sample appeared honesty better discriminatory, and that the form of the distribution tends to moderation larger sample size.
