Section AProbabilities of Single-Step Events
Chance Experiments
I can describe the likelihood of events using the words “impossible,” “unlikely,” “equally likely as not,” “likely,” and “certain.”
I can tell which event is more likely when the chances of different events are expressed as fractions, decimals, or percentages.

Section CSampling
Comparing Groups
I can calculate the difference between two means as a multiple of the mean absolute deviation.
When looking at a pair of dot plots, I can determine whether the distributions are very different or have a lot of overlap.
Larger Populations
I can explain why it may be useful to gather data on a sample of a population.
When I read or hear a statistical question, I can name the population of interest and give an example of a sample for that population.
What Makes a Good Sample?
I can determine whether a sample is representative of a population by considering the shape, center, and spread of each of them.
I know that some samples may represent the population better than others.
I remember that when a distribution is not symmetric, the median is a better estimate of a typical value than the mean.
