STATISTICS & PROBABILITY
- Formulating questions, designing studies, and collecting data about a characteristic shared by two populations or different characteristics with one population.
- Selecting, creating, and using appropriate graphical representations of data, including histograms, box plots, and scatter plots.
- Finding, using, and interpreting measure of center and spread, including mean and inter-quartile range.
- Discussing and understanding the correspondence between data sets and their graphical representations, especially histograms, and scatter plots.
- Using observations about differences between two or more samples to make conjectures about the populations from which samples were taken.
- Making conjectures about possible relationships between two characteristics of a sample on the basis of scatter plots of the data and approximate lines of fit.
- Using conjectures to formulate new questions and plan new studies to answer them.
- Understanding and using appropriate terminology to describe complementary and mutually exclusive events.
- Using proportionality and a basic understanding of probability to make and test conjectures about the results of experiments and simulations.
- Computing probabilities for simple compound events, using such methods as organized lists, tree diagrams, and area models.
