To complete the Rbar calculation, we use the information from Methods and Formulas to come up with the denominator; n is the number of data points (in this example itâs 100), wâs default value is 2 ,and we add 1, so the denominator is 100-2+1. In Minitab, we can once again use Calc Calculator to store the results in C5:
Federal Wage Garnishment Limits for Judgment Creditors. If a judgment creditor is garnishing your wages, federal law provides that it can take no more than: 1  25% of your disposable income, or. 2  the amount that your income exceeds 30 times the federal minimum wage, whichever is less.
1 In this example, the garnishable amount is $450.00 ($3,000 â $1,200  25%).  Pursuant to a garnishment order (with priority) for child support, an employer withholds $90.00 a week from the wages of an employee who has disposable earnings of $295.00 a week. A garnishment order for the collection of a defaulted student loan is also served. The limit for normal garnishments of 25% applies to the debt for the outstanding student loan. Under the formula for normal garnishments, a maximum of $73.75 (25%  $295.00) is garnishable.
