Chapter 17: Time Series Analysis and Forecasting
Here near the end of the semester well look at a totally new topic, time series analysis
and forecasting. We saw the basic definition of a time series in Chapter 1; it was said
simply that a time series is
Chapter 9: Hypothesis Tests
We are constantly bombarded by quantitative claims in the media. Advertisers make claims

Continuous random variables are described by probability density functions, or PDFs, which
represent probabilities. Since the area
Chapter 5: Discrete Probability Distributions
We continue our study of probability by learning the concepts of random variables and
probability distributions. We will discuss these concepts for both discrete and continuous
quantities. While the new defini
Chapter 8: Interval Estimation
In Chapter 8 we address one major type of statistical inference, the confidence interval.
We will see different forms of confidence intervals for means and proportions under
different assumptions. The general form of a confi

Chapter 4: Introduction to Probability
In Chapter 4 we learn to develop our ability to think probabilistically. We will focus on a
number of definitions, then on rules of probability. I believe it helps to think of these
things as tools in a toolbox that
Chapter 3: Descriptive Statistics: Numerical Measures
In Chapter 2 we learned about ways to represent data graphically. Now, in Chapter 3 we
will see how to characterize a dataset more precisely using numerical descriptors.

Well focus on a concept called Simpsons Paradox that arises when data in two or
more cross tabulations are combined, or aggregated to produce summary cross tabulations.
Well see that we must be careful when drawing conclusions b

1.1 Statistics
The term statistics can refer to numerical facts such as averages, medians,
percents, and index numbers that help us understand a variety of business and
economic situations.
Statistics can also refer to the

Chapter 2: Descriptive Statistics
Descriptive statistics are meant to provide quick and efficient summaries of data.
Descriptive statistics are usually differentiated from inferential statistics, which will be
the subject of subsequent chapters. As we wil
