Galaxy Hunter
Teacher Page: National Standards
The Online Exploration Galaxy Hunter includes four activities:
“Bias,” “Sample Size,” HDFN vs. HDFS,”and “The Last Stop.”
Learning Outcomes  McREL Standards and Benchmarks  ITEA Standards for Technological Literacy 
In “Bias” students will be able to analyze and identify sampling methods that reduce bias. 
Mathematics Standard 6. Level IV (Grades 912) Benchmark 8: Understands how concepts of representativeness, randomness, and bias in sampling can affect experimental outcomes and statistical interpretations. 
Standard 12: Students will develop the abilities to use and maintain technological products and systems. Grades 912 Benchmark P: Use computers and calculators to access, retrieve, organize, process, maintain, interpret, and evaluate data and information in order to communicate. 
Learning Outcomes  NCTM Principles and Standards 2000  McREL Standards and Benchmarks 
In “Sample Size” students will be able to:

Data Analysis and Probability Standard
Develop and evaluate inferences and predictions that are based on data.

Mathematics Standard 6. Level IV (Grades 912) Benchmark 7: Understands sampling distributions, the central limit theorem, and confidence intervals. Benchmark 8: Understands how concepts of representativeness, randomness, and bias in sampling can affect experimental outcomes and statistical interpretations. 
Learning Outcomes  National Science Education Standards  Project 2061 Standards  NCTM Principles and Standards 2000  McREL Standards and Benchmarks 
In “HDFN vs. HDFS” students will be able to:

Content Standard A: Understandings About Scientific Inquiry. Mathematics is essential in scientific inquiry. Mathematical tools and models guide and improve the posing of questions, gathering data, constructing explanations and communicating results. 
2. The Nature of Mathematics:

Data Analysis and Probability Standard

Mathematics Standard 6. Level IV (Grades 912) Benchmark 9: Understands that making an inference about a population from a sample always involves uncertainty and the role of statistics is to estimate the size of that uncertainty. 
Learning Outcomes  NCTM Principles and Standards 2000  McREL Standards and Benchmarks 
In “The Last Stop” students make a prediction based on data collection and analysis. 
Data Analysis and Probability Standard Grades 912.
