dc.description.abstract	Often in the linear correlation coefficient calculations for its statistical significance estimation is used the famous Chaddock's scale of the relationship between the studied phenomena with the characteristics like “weak”, “medium”, “visible”, “high”, “very high”, and for the significance evaluation used the Student's t-test table with the alpha-level α = 0.10; 0,05; 0.01 with the available degrees of freedom. So, the significance in both cases is assessed on a step by step manner, which is not fully expedient. For this problem decision is proposed a modified Student's scale and then it is possible to use the Chaddock's scale. As the raw data we use statistical aggregates with the limited size; after some modifications we create on this variation series and apply the consent criteria. For the noted problem solving we also must note the received equations for CLC error and non-strict inequality. Some part of the results was also obtained with the author's program in FoxPro 2.5.	ru_RU
