Report, if known, which group apparently has the highest values for the quantitative variable and which has the lowest. Tell if results are being reported for a sample or for an entire population, and the number of individuals studied, if known. Tell if there is reason to suspect bias that arises if the sample is not representative, or bias in the design for assessing the variable's values.
