North Carolina Standard Course of Study
NC.6.SP. Statistics and Probability
Develop understanding of statistical variability.
NC.6.SP.3. Understand that both a measure of center and a description of variability should be considered when describing a numerical data set.
NC.6.SP.3.a. Determine the measure of center of a data set and understand that it is a single number that summarizes all the values of that data set.
NC.6.SP.3.a.1. Understand that a mean is a measure of center that represents a balance point or fair share of a data set and can be influenced by the presence of extreme values within the data set.
NC.6.SP.3.a.2. Understand the median as a measure of center that is the numerical middle of an ordered data set.
NC.6.SP.3.b. Understand that describing the variability of a data set is needed to distinguish between data sets in the same scale, by comparing graphical representations of different data sets in the same scale that have similar measures of center, but different spreads.
Summarize and describe distributions.
NC.6.SP.5. Summarize numerical data sets in relation to their context.
NC.6.SP.5.b. Analyze center and variability by:
NC.6.SP.5.b.1. Giving quantitative measures of center, describing variability, and any overall pattern, and noting any striking deviations.
