Benchmark MACC.912.S-IC.1.1 Reporting Probability and Statistics Category Standard Making Inferences & Justifying Conclusions Benchmark MACC.912.S-IC.1.1 Number Benchmark Understand statistics as a process for making inferences about population parameters based on a random sample from that population. Benchmark Students will calculate, summarize, and interpret data using measures of Clarification center including mean and median and measures of spread including range, standard deviation, and variance. Students will use these measures to make comparisons and draw conclusions about data sets. Also Assesses MACC.K12.MP.5.1, MACC.K12.MP.6.1 or Assessed by Item Types This benchmark will be assessed using FR, GR, and MC items. Content Limits Items may include calculations for mean, median, variance, and standard deviation. Items may include the choice of which measure of center is the best representation of a data set. Benchmark Students will calculate, summarize, and interpret data using measures of Clarification center and spread. Stimulus Items must be set in mathematical or real-world context. Attributes Response Responses will be rational numbers. Attributes Sample Items Sample Item 1 MC The average grade point average (GPA) for 25 top-ranked students at a local college is listed below. (Use the rounding rule for the mean). 3.80 3.77 3.70 3.74 3.70 3.86 3.76 3.68 3.67 3.57 3.83 3.70 3.80 3.73 3.67 3.78 3.75 3.73 3.65 3.66 3.75 3.64 3.78 3.73 3.64 Find the mean of the GPAs.
