Websters MethodFind a modified divisor, d, such that when each groups modified quota (groups population divided by d) is rounded to the nearest whole number, the sum of the whole numbers for all the groups is the number of items to be apportioned. The modified quotas that are rounded are called modified rounded quotas.Apportion to each group its modified rounded quota.https://www.youtube.com/watch?v=ZNybGTvz_hQEx:The Rapid transit services operates 130 buses along six routes A, B, C, D, E, F.

ALWAYS compare mean quota to the apportion.Continue modifying divisor until apportion number is the correct total.

Ex: Refer to the previous example about the Rapid Transit Service to calculate the mean quota and verify using the LQ & RUWill it always work out that way?

No, you may have to modify the divisorSo.What do you notice about the names of the Apportionment Methods? (they are all named after presidents)
