Unit Title Unit Understandings and Goals RecommendedDurationUnit #9: Chi-Square AnalysisUnit #10: Independent ProjectsTo determine if two data sets affect each other, Chi-Square analysis is used.1. Students will determine if independence exists between two sets of data by utilizing the Chi-Square Test for Independence.2. Students will determine if significant differences exists between two data sets by using Chi-Square Goodness-of-Fit test.Technology is integral to the study of statistics.Proper experimental design is necessary to ensure non-biased results.1. Students will create a project utilizing many of the topics covered in the course.2. Students will utilize technology, such as spreadsheets, graphing calculators, and graphingsoftware to analyze data and create their project.3 weeks3 weeks7
Freehold Regional High School DistrictProbability & StatisticsUnit #1: What is Statistics?Enduring Understandings: Statistics is necessary to make accurate decisions involving data.Proper experimental design is necessary to ensure non-biased results.Essential Questions: How does one define statistics? Why is accurate decision making important?What are some implications of the inappropriate use of data? What considerations should be made when designingan experiment? What does it mean for results to be considered biased?Unit Goals: Students will examine the role of statistics in decision making processes.Students will define the necessary steps to ensure proper experimental design and critique current published research for hidden biases.Duration of Unit: 2 weeksNJCCCS: 8.1 A1, 9.2 A1-5; B1-3; C1-2; D1-5, 4.4 A1-6Guiding / Topical QuestionsWhat are the two types of statistics?What is the difference between a sample and apopulation?What are the different levels of measurementthat can be applied to data?What is involved in ensuring properexperimental design?How can one truly ensure a selection of randomsamples?What does it mean for an experiment to bebiased?What is a double-blind experiment and how arethey used?What is a placebo effect?Content, Themes, Concepts, and SkillsDescriptive statistics involves methods of organizing, picturing, and summarizinginformation from data.Inferential statistics uses samples to make inferences about a population.Define a sample and a population and show examples of each.Define the four levels of measurement: nominal, ordinal, interval, and ratio.List steps necessary to follow when creating an experiment.Show how to use a random number table and how to generate a random number on thegraphing calculator.Define bias and show examples of how bias may be introduced.Define a double-blind experiment and show how it is used.Define placebo effect with an example.InstructionalResourcesandMaterialsCurrent textbookand resourcebindersInternetMagazinesNewspapersVideosGraphingCalculatorsTeachingStrategiesLecture and classdiscussionComplete thechapter studyguidesStudentinvestigationactivitiesAssessmentStrategiesWritten tests andquizzesWorksheetsProject assessmentsNotebookassessmentsResponses todiscussion questionsJournal assessmentsStudent responsesystems for immediatefeedbackSuggestions on how to differentiate in this unit:• Students will work individually, engage in cooperative learning, and utilize discovery learning on certain activities.• Through the use of lectures, the internet, and interactive whiteboards, students will be exposed to various teaching methods to appeal to visual, auditory, and kinesthetic learners.• Students will be given copies of data sets and other important notes.8
