## Statistics 1A -- math online

IN-CLASS FORMAT:

- highly interactive.
- goal: clarify and simplify the big ideas of the weekâ€™s material.
- purposeful repetition of big ideas and ideas that the class is demonstrating weakness.

ADMINISTRATIVE FORMAT:

- generally, two sections from the textbook per week.

Before Class:

- You read the sections before class. (usually two sections per week)
- You take short online quiz over reading material before class.

During Class:

- We highlight, clarify, and explain the BIG IDEAS from each section interactively during class.
- We demonstrate how to solve exercises during class.

After Class:

- You attack exercises/questions/problems (i.e., homework assignment) after class.
- You take short online test over the material after class. (usually two sections per week)

CONTENT (first semester = 1A = the stuff essential for being a well-informed citizen):

- Basic principles and underlying concepts of statistics â€”
- why statistics can fail or even â€œlieâ€
- how not to be fooled by â€œstatisticsâ€
- understanding basic concepts like â€œdouble-blind experimentâ€
- how certain kinds of graphs can be misleading

- Basic descriptive statistics
- types of data & data collection
- frequency distributions & histograms
- mean & standard deviation (variance) and z-scores & percentiles
- basic probability: procedure; outcomes; sample space; event
- â€˜random variableâ€™
- binomial distribution & Poisson distribution

CONTENT (second semester = 1B = the stuff essential for doing college statistics):

- How to use mean and standard deviation in order to answer questions like:

- does this vaccine help reduce incidence of such and such an infection?
- Is there any significant difference in high school studentsâ€™ math skills (or whatever)

- between Indiana & Colorado?
- between high school A and high school B?
- between Mr Kringâ€™s class using textbook X and Mrs Loudenâ€™s class using textbook Y?

- What must you know in order to answer these questions?
- Is your sample size large enough to make valid conclusions?

Both semesters, together, give a solid foundation for citizenship and for college study!

I gear the class to typical, inquisitive high school students who are good but not particularly great at math. Weaker math students will thrive because of the interactive nature of the class. Excellent math students will thrive because of the inquisitive nature of statistics as a academic discipline.

High school statistics and undergraduate statistics are not dependent on high-level-math. So this class is more conceptual than mathematical, particularly the first semester. An INQUISITIVE MIND is the fundamental requirement. Algebra 1 is the prescribed prerequisite.
