Use the statistics you computed to write a few sentences that describe the students surveyed: Describe the shape of the data Describe the center (mean? median?) of the data. Describe the variation in the data. Describe any outliers in the data. Describe any gaps in the data. Be sure to reference the students, instead of talking about data points -- give meaning to you statistics. Include your statistics in your sentences, too.
