Chapter 1 introduces statistics and differentiates between descriptive and inferential statistics. It aims to motivate business students to study statistics by presenting applications in business. Some key objectives are to define statistics, discuss its uses in business, and classify data by level of measurement. The chapter also outlines descriptive statistics, inferential statistics, and the different levels of data measurement. It emphasizes that understanding the data level is important for choosing the right analytical techniques.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Chapter 1
Introduction to Statistics
LEARNING OBJECTIVES
The primary objective of chapter 1 is to introduce you to the world of statistics, enabling
you to:
1. Define statistics.
2. Be aware of a wide range of applications of statistics in business.
3. Differentiate between descriptive and inferential statistics.
4. Classify numbers by level of data and understand why doing so is important.
CHAPTER TEACHING STRATEGY
In chapter 1 it is very important to motivate business students to study statistics by
presenting them with many applications of statistics in business. The definition of
statistics as a science dealing with the collection, analysis, interpretation, and presentation
of numerical data is a very good place to start. Statistics is about dealing with data. Data
are found in all areas of business. This is a time to have the students brainstorm on the
wide variety of places in business where data are measured and gathered. It is important
to define statistics for students because they bring so many preconceptions of the
meaning of the term. For this reason, several perceptions of the word statistics is given in
the chapter.
Chapter 1 sets up the paradigm of inferential statistics. The student will
understand that while there are many useful applications of descriptive statistics in
business, the strength of the application of statistics in the field of business is through
inferential statistics. From this notion, we will later introduce probability, sampling,
confidence intervals, and hypothesis testing. The process involves taking a sample from
the population, computing a statistic on the sample data, and making an inference
(decision or conclusion) back to the population from which the sample has been drawn.
In chapter 1, levels of data measurement are emphasized. Too many texts present
data to the students with no comment or discussion of how the data were gathered or the
2. Chapter 1: Introduction to Statistics 2
level of data measurement. In chapter 7, there is a discussion of sampling techniques.
However, in this chapter, four levels of data are discussed. It is important for students to
understand that the statistician is often given data to analyze without input as to how it
was gathered or the type of measurement. It is incumbent upon statisticians and
researchers to ascertain the level of measurement that the data represent so that
appropriate techniques can be used in analysis. All techniques presented in this text
cannot be appropriately used to analyze all data.

SOLUTIONS TO PROBLEMS IN CHAPTER 1
1.1 Examples of data in functional areas:
3. Chapter 1: Introduction to Statistics 3
accounting - cost of goods, salary expense, depreciation, utility costs, taxes,
equipment inventory, etc.
finance - World bank bond rates, number of failed savings and loans, measured
risk of common stocks, stock dividends, foreign exchange rate, liquidity rates for
a single-family, etc.
human resources - salaries, size of engineering staff, years experience, age of
employees, years of education, etc.
marketing - number of units sold, dollar sales volume, forecast sales, size of sales
force, market share, measurement of consumer motivation, measurement of
consumer frustration, measurement of brand preference, attitude measurement,
measurement of consumer risk, etc.
information systems - c.p.u. time, size of memory, number of work stations,
storage capacity, percent of professionals who are connected to a computer
network, dollar assets of company computing, number of “hits” on the Internet,
time spent on the Internet per day, percentage of people who use the Internet,
retail dollars spent in e-commerce, etc.
production - number of production runs per day, weight of a product; assembly
time, number of defects per run, temperature in the plant, amount of inventory,
turnaround time, etc.
management - measurement of union participation, measurement of employer
support, measurement of tendency to control, number of subordinates reporting to
a manager, measurement of leadership style, etc.
1.2 Examples of data in business industries:
manufacturing - size of punched hole, number of rejects, amount of inventory,
amount of production, number of production workers, etc.
insurance - number of claims per month, average amount of life insurance per
family head, life expectancy, cost of repairs for major auto collision, average
medical costs incurred for a single female over 45 years of age, etc.
travel - cost of airfare, number of miles traveled for ground transported vacations,
number of nights away from home, size of traveling party, amount spent per day
on nonlodging, etc.
retailing - inventory turnover ratio, sales volume, size of sales force, number of
competitors within 2 miles of retail outlet, area of store, number of sales people,
etc.
4. Chapter 1: Introduction to Statistics 4
communications - cost per minute, number of phones per office, miles of cable
per customer headquarters, minutes per day of long distance usage, number of
operators, time between calls, etc.
computing - age of company hardware, cost of software, number of CAD/CAM
stations, age of computer operators, measure to evaluate competing software
packages, size of data base, etc.
agriculture - number of farms per county, farm income, number of acres of corn
per farm, wholesale price of a gallon of milk, number of livestock, grain storage
capacity, etc.
banking - size of deposit, number of failed banks, amount loaned to foreign banks,
number of tellers per drive-in facility, average amount of withdrawal from
automatic teller machine, federal reserve discount rate, etc.
healthcare - number of patients per physician per day, average cost of hospital
stay, average daily census of hospital, time spent waiting to see a physician,
patient satisfaction, number of blood tests done per week.
1.3 Descriptive statistics in recorded music industry -
1) RCA total sales of compact discs this week, number of artists under
contract to a company at a given time.
2) total dollars spent on advertising last month to promote an album.
3) number of units produced in a day.
4) number of retail outlets selling the company's products.
Inferential statistics in recorded music industry -
1) measure the amount spent per month on recorded music for a few
consumers then use that figure to infer the amount for the population.
2) determination of market share for rap music by randomly selecting a
sample of 500 purchasers of recorded music.
3) Determination of top ten single records by sampling the number of
requests at a few radio stations.
4) Estimation of the average length of a single recording by taking a sample
of records and measuring them.
5. Chapter 1: Introduction to Statistics 5
The difference between descriptive and inferential statistics lies mainly in the
usage of the data. These descriptive examples all gather data from every item in
the population about which the description is being made. For example, RCA
measures the sales on all its compact discs for a week and reports the total.
In each of the inferential statistics examples, a sample of the population is taken
and the population value is estimated or inferred from the sample. For example, it
may be practically impossible to determine the proportion of buyers who prefer
rap music. However, a random sample of buyers can be contacted and
interviewed for music preference. The results can be inferred to population
market share.
1.4 Descriptive statistics in manufacturing batteries to make better decisions -
1) total number of worker hours per plant per week - help management
understand labor costs, work allocation, productivity, etc.
2) company sales volume of batteries in a year - help management decide if
the product is profitable, how much to advertise in coming year, compare
to costs to determine profitability.
3) total amount of sulfuric acid purchased per month for use in battery
production. - can be used by management to study wasted inventory,
scrap, etc.
Inferential Statistics in manufacturing batteries to make decisions -
1) take a sample of batteries and test them to determine the average shelf life
- use the sample average to reach conclusions about all batteries of this
type. Management can then make labeling and advertising claims. They
can compare these figures to the shelf- life of competing batteries.
2) Take a sample of battery consumers and determine how many batteries
they purchase per year. Infer to the entire population - management can
use this information to estimate market potential and penetration.
3) Interview a random sample of production workers to determine attitude
towards company management - management can use this survey results
to ascertain employee morale and to direct efforts towards creating a more
positive working environment which, hopefully, results in greater
productivity.
