Question

Quizplus · Accepted Answer

Open-ended intervals can be useful when there are a few very high or very low scores in a distribution. This allows for the inclusion of those extreme scores without distorting the rest of the distribution. However, it is important to ensure that the majority of the data falls within the defined intervals and that the open-ended intervals do not create a bias in the data. Unequal intervals may be necessary in some cases, such as when dealing with variables that have a wide range of values, but they can make it difficult to compare between groups or draw meaningful conclusions. Open-ended intervals can be used with variables of any level of measurement.
