Unit 2: Data and Graphing

5.1 Collect and Organize Data p Introduction: Quick Review Objective: Learn how to collect data by using surveys and to organize data in frequency tables and line plots HW: p. 98 #4-14 Vocab : survey= sample= population= random sample= cumulative frequency= outlier= range= Glossary

Guided Instruction: Topic: Team Names Sample: ______________ Question: __________________________________ ResponsesNumber of Students

Guided Instruction: Example 1: Pet Survey Number of PetsFrequencyCumulative Frequency

26.3 Odds p. 586 Introduction: Quick Review Objective: To write odds in favor and against an event Vocab : odds in favor of an event= one possible outcome odds against an event= set of ALL possible outcomes Glossary

Guided Instruction: Example 2: Finding the odds in favor/against an event BOOKKEEPER A. Odds in FAVOR of choosing O (favorable 2, unfavorable 8) = ___/___, _____ to _____, or _____ : ______ B. Odds AGAINST choosing K or P (unfavorable 7, favorable 3) = ___/___, _____ to _____, or _____ : ______

26.5 experimental probability p. 590 Introduction: Quick Review Objective: To write odds in favor and against an event Vocab : experimental probability= number of times a favorable outcome actually occurs compared w/ the total number of times you do an activity: experimental probability = number of favorable outcomes that occur/total number of trials Glossary

Guided Instruction: Example 1: Finding the experimental probability of an event Green (2), Red (10), Yellow (13) P (green) = 2/25,.08, 8% P (red) = 10/25=2/5,.40, 40% P (yellow) = 13/25,.52, 52% Theoretical Probability?? Pablo had 10 green __________, 50 red __________, and 40 yellow_____________

RECAP : Match the vocab word with its definition one possible outcome set of ALL possible outcomes one possible outcome number of times a favorable outcome actually occurs compared w/ the total number of times you do an activity: experimental probability = number of favorable outcomes that occur/total number of trials set of ALL possible outcomes P, number of FAVORABLE to POSSIBLE results: P (event) = number of favorable outcomes/number of possible outcomes outcome odds in favor of an event sample space experimental probability theoretical probability odds against an event I = prt
