An acceptable error range depends on the application. For example, a 5-10% error range on politic The proper place to put a percent sign in a range is as follows: 40-60% The percent sign is not used after both ranges (40 and 60) when ranges are used.

A range is an interval that defines the minimum and maximum values for any set of numbers or for the variation of a particular variable — a stock price on the market, for example. The percent relative range refers to the percentage ratio of the range to the average

It depends on the purpose of the model. A model may be considered valid if it provides useful output. What is useful depends on the context. Often, it is decision-making. Then the question is: what is the maximum percentage error that the model ca
