In Ehe exaEnple on page three, i-test <br />results would not be used beeause the <br />underpayment ratio is above SO%, bui <br />let's assu�ne we needed to check tl�ese <br />results. First, we would find 16 in the DF <br />colunnn and then Ioak acrass to �ind the <br />value af t at 1.746. Since aur t-test number <br />is -3.732, well below the value of t on the <br />table, th�se resuIts would show that on <br />average, females are not underpaid <br />compared to rnales. <br />T-Test Table <br />{5% Significance) <br />DF <br />1 <br />2 <br />3 <br />4 <br />6 <br />7 <br />8 <br />9 <br />10 <br />11 <br />Value of t DF Value of t DF <br />6.314 <br />2.920 <br />2.353 <br />2.132 <br />2.Q1S <br />1,943 <br />1.895 <br />1.860 <br />1.833 <br />1.812 <br />1.796 <br />12 1.782 <br />13 1.771 <br />14 I.761 <br />15 1 7S3 <br />� � <br />`'ti�w�kir��.,�'�� s��;������A.. � . ��:a:�t`�6n=�� r-,_::s> <br />17 I.740 <br />18 I.734 <br />l9 �.729 <br />24 �.725 <br />21 1.721 <br />22 1.717 <br />23 <br />24 <br />25 <br />26 <br />27 <br />28 <br />29 <br />3Q <br />40 <br />60 <br />120 <br />Value of t <br />1.7I4 <br />1.7II <br />1.7Q8 <br />1.706 <br />1.703 <br />1.701 <br />1.699 <br />1.697 <br />1.b84 <br />1.671 <br />1.658 <br />1.fi45 <br />While the entire method for caIculaiing t-test <br />results cannot be explained here, it is a <br />coznmonly accepted rnathematical technique <br />for measuring statistical significance. The <br />formula is fairly complex, bu# basicalIy it <br />factors in predicted pay, the dollar <br />difference fram predicted pay and the <br />number of employees. The DF number is <br />the total number of employees in rrzale or <br />female daminated classas only, �ninus two. <br />8. Average Dollar Amount Male Classes are <br />Above or Below Predicted Pay <br />In the example on page three, the maximum <br />monthly salary far male cIasses, on average, <br />is $2 above predicted pay. <br />9. Average Dollar Amount Female Classes <br />are Above or Below Predicted Pay <br />In the example on page th�'ee, the maximum <br />monthly salary for female classes, on <br />auerage, is $75 above pr�dicted pay. <br />10. Sa[ary Range Test <br />This number must be either 0% or 80% or <br />more to pass this test. In the example on <br />paga three, i 45.7 i% is passing. <br />Jurisdictions not passing this test can pass it <br />by reducing the number of years it takes for <br />ferriale classes to reach maximum salaries, <br />increasing the number of years for males to <br />reach maximum salaxzes, or some <br />combination af both. A result of 0% would <br />mean that either there are no male classes <br />with an estabIished nu�nber of years to move <br />through a salary range, no female classes <br />with an estabIished nu�nber of years to move <br />through a saIary range, or l�oth. A <br />descriptian of how the salary range test is <br />calculated is on page 12. <br />1 I. Exceptiona[ Service Pay Test <br />This number nnust be either 0% ar 84% or <br />more ta pass this test. In the exatnple on <br />page three, 50% is not passing. Jurisdictions <br />not passing this test can pass it by either <br />increasing ihe nunnber of fernale classes that <br />receive exceptional service pay, decreasing <br />the number of �nale classes that receive <br />exceptional service pay, or sozne <br />combination of both. A result of p% could <br />mean that fewer than 20% of male cIasses <br />receive exceptional service pay or that no <br />female classes receive exceptional service <br />pay. A description of how the exceptional <br />service pay test is caIcuIated is on page 13. <br />Guide to Understanding Pay Equity Compliance and Computer Reports — 11110 Page 5 <br />
