So, What Is Statistics?
Our ability to answer questions and
draw conclusions from data
depends largely on our ability to
understand variation.
The key to learning from data is
understanding the variation that is
all around us.

Why the Need for Statistics?
Learning statistical concepts and methods will empower
you to draw conclusions from data and make valid
business decisions in response to such questions as:
Do university students from different parts of the world
perceive business ethics differently?
What is the effect of advertising on sales?
Do aggressive, “high-growth” mutual funds really have
higher returns than more conservative funds?
Is there a seasonal cycle in your firm’s revenues and
profits?

you to draw conclusions from data and make valid
business decisions in response to such questions as:
What is the relationship between shelf location and
cereal sales?
How reliable are the quarterly forecasts for your firm?
Are there common characteristics about your
customers and why they choose your products?—and,
more importantly, are those characteristics the same
among those who aren’t your customers?


Math was never my strong suit but you never gave up
on any of us. You pushed us to understand
complicated topics, and I am so grateful for that. I
see things you teach me in the real world all the time,
I just sat in on a Quality workshop at my job, and it
was all about normal distribution and box graphs etc.
I thought of you and all of the things I would never
have known if it weren't for your class!
