Students use data samples of a population and describe the characteristics and limitations of the samples 

Skills: 

2.1 Compare different samples from a population with the data from the entire population and identify when it makes sense to use a sample.

2.2 Identify different ways of selecting a sample and decide which makes a sample more representative for a population. 

2.3 Analyze data displays and explain the results obtained, and/or how the way the results were displayed might have influenced the conclusions reached. 

2.4 Identify data that represent sampling and explain why the sample (and the display) may be biased. 

2.5 Identify claims based on statistical data and, in simple cases, evaluate the validity of the claims. 

Students determine theoretical and experimental probabilities and use these to make predictions about events 

Skills: 

3.1 Represent all possible outcomes for compound events in an organized way, and express the theoretical probability of each outcome. 

3.2 Use data to estimate the probability for future events. 

3.3 Represent probabilities as ratios, proportions, and decimals between 0 and 1, and percents between 0 and 100 and check that probabilities computed are reasonable; know how this is related to the probability of an event not occurring. 

3.4 Understand that the probability of either of two disjointed events occurring is the sum of the two individual probabilities, and that the probability of one event following another, in independent trials, is the product of the two probabilities. 

3.5 Understand the difference between independent and dependent events and how this affects the results for specific probability situations.
