Check-in 1.Any questions about the syllabus or the course in general? 2.If you know of students who have not shown up to school at Fenger, PLEASE ENCOURAGE THEM TO COME TO SCHOOL! 3.This week we will begin to do more in-depth discussions on research and statistics 4.You will also have some readings to complete Daniels/Stadeker Advanced Math

What Is Statistics? Most people become familiar with probability and statistics through various media (radio, TV, Internet, newspapers, and magazines) – Nearly one in seven US families are struggling with bills from medical expenses even though they have health insurance – About 15% of men in the US are left-handed and 9% of women are left-handed – The median age of couples who watch Jay Leno is 48.1 years – Eating 10 grams of fiber a day reduces the risk of heart attack by 14% Daniels/Stadeker Advanced Math5

Where Do We See Statistics? Statistics is used in almost ALL fields of human endeavor. – Sports: a statistician may keep records of the number of yards a running back gains during the football game OR number of hits a baseball player gets in a season – Public Health: an administrator might be concerned with the number of residents who contract a new strain of flu virus – Education: a researcher might want to know if new teaching methods are better than old ones. Daniels/Stadeker Advanced Math6

The Language of Statistics Variable: a characteristic or attribute that can assume different values Variables whose values are determined by chance are called random variables Data: values (measurements or observations) that variables can assume Data is the information collected – the group of information forms a data set Each value in the set is a data point or datum Daniels/Stadeker Advanced Math7

Population vs Sample PopulationSample ALL subjects (human or otherwise) that are being studied Examples All citizens of the United States All students enrolled at FHS during Fall 2013 The governors of the 50 United States “Small” group of subjects (human or otherwise) selected from the population Examples 1000 adult Americans surveyed to determine if he/she favors the legalization of marijuana 21 students in Mr. Daniels’ math class surveyed to determine height Mr. Daniels Advanced Math8

Where do I stand? In this exercise, you will be given a description The description may be a population OR it may be a sample If you think it is a population, write population If you think the description is a sample, write sample Daniels/Stadeker Advanced Math9

Where do I stand? Which of the following are populations? All institutionalized elderly with Alzheimer's in Cook county nursing homes All people with AIDS All pregnant teens in Cook County All students who made the Honor Roll last year All students in Illinois who took the ACT Daniels/Stadeker Advanced Math10

Journal Topic Provide an example of a population & a sample Describe someone who is a hero to you and explain why Daniels/Stadeker Advanced Math11

Sample Data Collection Instructions: You will work in one group Your group must – Define a population in your own words – Define a reasonable sample of your population – Determine the type of data you could collect against your sample – Create a presentation (drawing) that illustrates your population, sample and data Each group will give a readout This is a graded assignment Mr. Daniels Advanced Math12

HAVE A GREAT TUESDAY!!! Mr. Daniels Daniels/Stadeker Advanced Math
