 think critically about how each measure would be affected if the highest score was eliminated from the data set. Explain if each measure (mean, median, mode, range, and standard deviation) would increase, decrease, or stay the same.

 Use the relative positions of the mean, median, and mode to identify the shape of the distribution (positive skew, negative skew, or normal distribution). Explain what the shape of this distribution tells you about the sample.
