The range of swim times is 5.6 hr. The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Every month that you make a partial payment, your credit card account will fall further and further past due. You will go from 30 to 60 to 90 days past due. This information will be reported on your credit file and your credit score will be lowered.
Looking at this chart again, we can see that late payments that are 30 days past due will drop a 900 point credit score by as much as 90 points and a 60 day late payment can cause a 105 point drop. Meanwhile, payments that are 90 or 120 days late will drop a 900 point credit score by roughly 100-160 points.
