About This Course
Data Analysis is an ever evolving discipline with lots of focus on new predictive modeling techniques coupled with rich analytical tools that keep increasing our capacity to handle big data. However, in order to chart a coherent path forward, it is necessary to understand where the discipline has come from since its inception.
The field of Business intelligence depends largely on Data analysis tools and techniques in order to inform effective decision making. In fact, the disciplines are so intertwined that some often confuse the two. Therefore, we begin our introduction by examining the history of Business intelligence, its relationship to data analysis, and why the two are needed to help businesses deliver a complete assembly of their 'data puzzle'. This module also addresses some of the hurdles businesses face when dealing with data overload, and suggests some possible solutions to the problem.
With the explosion of big data, businesses recognize there is a greater need for employing someone who is qualified to correctly analyze the data. In this module, we explore the qualifications for the data analyst as well as the analytic tools associated with the position. It is unfortunate that there is such a dearth of data analysts. With a projected shortage of 190,000 data science jobs into 2018, it is no wonder that businesses are scrambling to recruit talent.

FACTS or Feelings: Your Choice
As data becomes more widely available, businesses are finding more success in adopting a fact based decision model rather than relying on traditional intuition alone. In this module, we examine more closely the two types of decision models businesses use as well as the benefits of the factbased model. We cover the steps of the Rational Decision Model , a fact based method for decision making.

'BIG DATA' ANATOMY
In this module, we revisit the Big Data trend with a more detailed focus. We begin by defining the buzz word"BIG DATA" , examining its core attributes, and outlining the factors that contribute to data being 'big'. We explore how businesses collect structured and unstructured data, and the challenges they face in storing and effectively using both types of data.
V. Big Data Anatomy
 The Attributes of Big Data
 Definition of Big Data
 The 4 V's of Big Data
 Structured versus Unstructured Data
 The Challenges of Big Data
Exercise: "Camp WoeBeData" Students are asked to describe some of the big data challenges that their companies face and to outline what steps are being taken to address the problems.
GETTING TO KNOW YOUR DATA
In order to better understand how to analyze data, we first have to comprehend its depth. This requires drilling deep beneath the server it is located on and understanding its composition. Assume we are given a structured data set with labeled columns and completed rows . There are plenty of ways to summarize the story behind the data, but we cannot dive in without first getting to understand its fundamental structure. We begin by classifying the collected data as quantitative or qualitative. Then we further classify our column variables according to the way data is measured: nominal, ordinal, interval, or ratio. It is only after understanding this classification that we are able to proceed to the next step of choosing the appropriate analysis techniques which correspond to nominal, ordinal, interval or ratio variables.
VI. Getting to Know Your Data
 Data Types: Qualitative versus Quantitative
 Taking a Closer Look: Data Measurement
Four Types of Data Variables

Exercise: "Marketing to Low Renters"  Students are told to put on their data analyst thinking caps. They have been employed as a junior data analyst for a Marketing Company whose goal is to make a marketing campaign for a client who plans on targeting the 'needy' population. Students are given a public housing data set and told to classify each variable according to its measurement.
DATA VISUALIZATION
A picture is worth a thousand words, and there definitely is no exception when it comes to summarizing data. This module is dedicated to highlighting the importance of visualizing data, and how the human eye depends on visual representation to get a quick sense of data relevance. Visual representation is the audience's first impression of the data and forms a crucial step in inviting and maintaining genuine interest in a subject matter. We demonstrate how to create colorful, easy to understand tables, charts, and graphs that aid in helping us convey the story behind the data set being analyzed.

Exercise: "Charting Poverty" Students develop charts and graphs to summarize the poor housing epidemic in a public housing data set.
NUMERICAL DATA SUMMARIES
Another way that data analysts summarize data is by providing a single number , or summary statistic, that has meaning. This module explores how the mean, median, and mode can be used to summarize the center of discrete and continuous grouped data . The range, standard deviation, and interquartile range measure the dispersion in the data set and provide information about how data points are spread.

Exercise:"Faulty Wear: Take 2" Students use measures of spread to summarize the distribution of faulty garments from a department store.
QUANTIFYING UNCERTAINTY
Probability is not only the most important data analysis foundation, but it is by far the strongest measure that businesses can use to quantify uncertainty. There are risky decisions that businesses encounter when investing in certain stocks and taking a chance on whether its value will rise. The insurance industry calculates the most probable life expectancy for the population and bases its rates on that uncertainty. There are an abundance of examples that illustrate why understanding probability benefits the business industry, so this module is designed to expose students to a solid understanding of the topic. We use simple, easy to understand examples to introduce students to traditional and conditional probability. Then we follow up with other business probability applications that involve relative frequency and expectation.

Exercise: "Peck Up Your Speed"Students analyze the relative frequency of workers' typing speeds.
Exercise: "Rent Me"Students calculate expected value in order to assist the Callow Corporation in making an important decision regarding leasing computer equipment.
NORMALITY
If you look at the graph of your data and notice that it looks like a bellshaped curve, it probably follows a normal distribution. The manufacturing industry, for example, measures volumes and weights of products. Data collected from these instances are normally distributed. In fact, if we take any process and calculate its mean value enough times, then its mean value is also normally distributed. This module examines the famous 'Normal Distribution' and how it can be used to provide useful information about the probability of certain events.
XII. The Normal Distribution
 Examples of Normally Distributed Data Variables
 Characteristics of the Normal Distribution

ASSOCIATION AND PREDICTION
If we have data measurements for at least two variables, it is natural to ask if there is some relationship between the two. This module takes a look at the two strongest measures of association, correlation and regression, and explores how to use them to quantify the relationship. It also examines how regression output can be used to predict future observations.
XIII. Correlation and Regression
 Definition of Correlation and Regression
 Relationship between Correlation and Regression
 Correlation Coefficient: Values
 Examples of Correlation
