I may have miscommunicated but I wasn't concerned with the realism of the costs - I was questioning the relation of the values.
If you have two sets of numbers, S and T, then I'm quite confident MEAN(S ∪ T) must fall between MIN(MEAN(S), MEAN(T)) and MAX(MEAN(S), MEAN(T)) inclusive.
In this case, the costs of maintenance for a given vehicle model are the sets and, so, the cost for a brand as a whole would be (S ∪ T ∪ V...).
- Jupe 10y agoYeah, I got ya now. The problem is that repairs can continue. $450 for brakes? Ok. $800 for tires + alignment. $125 for a new battery. $600 to replace a bent rim and it's pair. When data like this indicates that the maintenance cost of BMWs or other vehicles is higher, it's not just a question of quality: many times the parts + labor are just more expensive.
- runT1ME 10y agoNo, you don't. He's saying the math doesn't add up in terms of how they calculated the mean of the brand and the 'highest' avg. mean of the models (in that brand).
- Jupe 10y agoYes, I do... the single model 328i, if it is in fact the worst of the BMW models, should be above the average cost of the BMW models. According to the first table, it isn't. They made a mistake.
