• identify the difference between categorical and quantitative (numerical) data
• analyze patterns and trends in data displays
• interpret results by interpreting the analysis and relating the interpretation to the original question
• create a sampling distribution of a statistic by taking repeated samples from a population (either hands-on or by simulation with technology)
• determine the type of data used to produce a given graphical display
• describe and interpret the shape of the distribution
• identify the three types of distributions
• distinguish the roles of randomization and sample size with designing studies
• distinguish between the role of randomness and the role of sample size with respect to using a statistic from a sample to estimate a population parameter
• identify whether the data are categorical or quantitative (numerical)
• distinguish between a population distribution, a sample data distribution, and a sampling distribution
• describe and interpret the modal category for the distribution
• create simulated sampling distributions and understand how to use the sampling distribution to make predictions about a population parameter(s) or the difference in treatment effects
• apply the statistical method to real-world situations
• create a sample data distribution by taking a sample from a defined population and summarizing the data in a distribution
• construct appropriate graphical displays of distributions
• create sample data distributions and a sampling distribution
• recognize a sample data distribution is taken from a population distribution and the data distribution is what is seen in practice hoping it approximates the population distribution 
• determine the appropriate scope of inference for the study design used 
• understand that randomness should be incorporated into a sampling or experimental procedure
• recognize a sampling distribution is the distribution of a sample statistic (such as a sample mean or a sample proportion) obtained from repeated samples; the sampling distribution provides the key for determining how close to expect a sample statistic approximates the population parameter
• understand that when randomness is incorporated into a sampling or experimental procedure, probability provides a way to describe the "long-run" behavior of a statistic as described by its sampling distribution
• distinguish between the three types of study designs for collecting data (i.e., sample survey, experiment, and observational study) and will know the scope of the interpretation for each design type
• compare two or more groups by analyzing distributions
• determine if an association exists between two variables (e.g., pattern or trend in bivariate data) and use values of one variable to predict values of another variable
• create scatter plots for two-variable numerical data
• describe and interpret the patterns in variability for the distribution
• using simulation, determine the appropriate model to decide if there is a significant difference between two populations
• recognize that sample size impacts the precision with which estimates of the population parameters can be made (i.e., larger the sample size the more precision)
• determine the appropriate graphical display for each type of data
• collect data by designing a plan to collect appropriate data and employ the plan to collect the data
