Transcript Probability - Appoquinimink High School

A
set of mathematical
techniques used to organize
and manipulate data for the
purpose of answering question
and testing theories.
#1
For graduation, you need to take four math
courses.
 Statistics is not “mathy”

› Minimal algebraic manipulations
› Mostly computational (you use your calculator a
lot)
› Relies mostly on your interpretation and analysis.

Statistics is a math course many students
stronger in writing are successful in.
#2
 Be
able to understand numerical
information and not be mislead.

Be a better consumer

Understand news reports

Understand medical tests

Understand results from surveys
#3
 Be
able to organize data in a
meaningful way

We are in a technological age where
information can be recorded easily

We need to have methods for organizing
the information so that we can make
meaning of it.
For example: UPS tracks every package
as it is shipped around the world.
 There are over 3.3 million UPS packages
shipped per day.
 For UPS to understand how well (or
poorly) they are doing as a postal
service, they need to be able to
organize the information on all 3.3 million
packages that are shipped each day.

#4
To be able to analyze the reliability of a
statistical statement.
 For example:
 “96 percent of all students at AHS prefer
football as their extracurricular activity”


This statement is based on a survey of 25
football players during football practice.
#5
In order to make sound
decisions.
 For example:


“Statistics show far fewer skateboarding
injuries during the winter while sledding
injuries are more common. Clearly, I’m
safer going down Popsicle precipice (a
sledding hill) on my skateboard” – Calvin
and Hobbes
#6

If you are planning on attending college,
you will most likely have to take an
introductory statistics course in college.

2 out of 3 students at the University of
Delaware are required to take a statistics
course as part of their degree program.

“Statistical thinking will one day be as
necessary for efficient citizenship as the
ability to read and write.”

1.
The course is split into 5 different areas of
statistics and probability
Exploring data
›
2.
Looking at sets of data and displaying them
graphically and describing them using
statistical methods.
Comparing data
›
Looking at two sets of data and
mathematically analyzing if there is a
relationship between the sets.
3.
Collecting Data
›
4.
Designing experiments and surveys to
collect data in a way that is meaningful for
statistical analysis.
Probability
›
Explore uncertainty and randomness to
determine the likelihood of the occurrence
of different events.
5.
Introduction to Statistical Inference
›
›
Use samples of data and use mathematical
methods to infer the trend for an entire
population.
This is the essence of statistics, but takes all
of the material discussed in the class to
build up to this point where we can take a
survey or experiment and then try to predict
with some accuracy how the results relates
to the whole population.
All students are expected to explain their
thinking & justify their conclusions
 All students should respectfully challenge
each other’s thinking
 All students should take initiative to explain
another student’s thinking, including
respectfully suggesting how they may have
made an error.
 Students who “get it” more quickly are
expected to take responsibility for assisting
others who are struggling.


70% Product – 450 points (69.2%)
› 3 exams per marking period for 100 points
each
› 2 statistical application assignments for 75
points each

30% Process – 200 points (30.8%)
› HW – 9 assignments for 20 points each
› Classwork & participation – 20 points
Homework – 200 points
Assigned weekly on the first day of each
week and due on Friday of each week.
 9 homework assignments each marking
period.
 Every homework assignment will be
worth 20 points.
 Late work will be accepted one day late
for 50% credit. After one day late work
will not be accepted.

We will apply concepts learned in class
through projects which include data
collection and analysis.
 There will be 2 projects each marking
period worth 75 points each.
 Each project will be graded using a
rubric that will be given out with each
project description.

There will be 3 exams each marking
period worth 100 points each.
 Exams will focus on the current unit of
study, but may include prerequisite
knowledge from previous units of study.

Out of all the math courses you have
taken, statistics prepares students most
for life outside of school.
 You will be able to read studies,
advertisements, and survey results from a
different perspective and be able to
make sound decisions.
 Work together, support each other, and
let’s make this a fun year!

Cows with names produce 68 more
gallons of milk…
Udder nonsense? Scientists think not. After
studying the working relationships between
farmers and dairy cows, researchers at
Newcastle University in the UK found that
farmers who gave Bessie and Gertrude TLC
reaped benefits of increased milk yield over a
10-month period. On average, a cow
produces about 1,981 gallons of milk during this
time span, but by referring to their cattle by
name, farmers saw a spike in milk production.
Scientists believe that personal attention
improves cows’ comfort levels lessening their
fear of human contact. This just goes to show
that even cattle don’t like being herded.
