PROBABILITY AND STATISTICS
The Best Math
Course I Ever Taught
Tired of hearing ÒWhen will I ever use this stuff?Ó Want to
bring real-life applications of mathematics to students headed for almost every
field? Teach AP Statistics – and donÕt restrict enrollment. This AP
course is for everyone!
Lines of Best
Fit – Fact and Fiction
How
and why does linear regression work? What do lines of best fit really say? And
what common misunderstanding appears frequently in textbooks and on exams?
Why Variances
Add – And Why It Matters
The
variance of the sum or difference of two independent random variables is the
sum of their variances. After the Central Limit Theorem, this is the most
important result in Statistics, yet it vexes students (and often their teachers
as well!) WeÕll see why the Pythagorean Theorem of Statistics is true, explore
ways to explain it to students, and examine important insights it reveals about
binomial probabilities, statistical inference, and even the Central Limit theorem
itself.
Is That an
Assumption or a Condition?
In
Statistics itÕs essential that we look before we leap: failure to check
assumptions and conditions can lead to inappropriate analyses and incorrect
conclusions. But why do we check what we check? And whatÕs the difference
between an assumption and a condition anyway? These insights will lead you and
your students to deeper understanding of statistical inference.
Making
Inference Make Sense
How
can we help students understand statistical inference? Begin preparing them
from the opening day of class by foreshadowing the key concepts and developing
the statistical thinking theyÕll need. Early on students can see that
statisticians compare real data to theoretical models, comparisons that are
valid only under certain assumptions. Inference concepts grow logically from
these roots, sprouting in an order that allows students to build a solid
understanding – one new idea at a time.
Making
Regression Inference Make Sense
Inference
for linear regression is one of the most challenging topics we teach in AP Statistics, but it also has the greatest
potential to unify and reinforce several important ideas and skills. WeÕll look
at the underlying concepts and conditions, examine an interesting sampling
distribution, and explore effective ways to teach these ideas. ItÕs the perfect
end-of-course, reviewing many key ideas and preparing students for the
impending AP exam.
Making
Statistics Make Sense (in AP Bio)
Testing
hypotheses about genetics without much familiarity with Statistics is sure to
raise some vexing questions among AP Bio students (and their teachersÉ)! WhatÕs
the reasoning behind hypothesis testing? What does a chi-square calculation
measure? What does a P-value mean? What can (and canÕt) we conclude?
Probability
and Statistics in Middle Schools
Why
is probability so tough to teach? Well, because the ideas are hard! WeÕll explore some of the issues through the eyes of
your students, and examine lessons that can help kids with probability. And
then weÕll explore some common misunderstandings, misapplications, and misuses
of Statistics.
