Selected Response (Multiple Choice), Gridded Response, Short Answer Item Types Benchmark Students will identify outliers, the possible reasons for them and what effect they have on the mean, median, mode and range of data. Clarification Content Items may include identifying outliers from a set of data in a graph such as a Limits histogram or box-and-whisker plot. Items may also include what effect adding a higher or lower value have on a particular mean, median, mode or range. Stimulus Items must be set in real-world context. Attributes Answers will include numerical outliers, reasons for outliers, or effect of specific Response Attributes outlier on mean, median, mode or range of data.
