Essential Statistical Concepts: Data Analysis and Modeling
Statistics: techniques (collecting,organizing,analysing,interpreting data)
Data may be:
quantitative (values expressed numerically) qualitative: (characteristics being tabulated). Descriptive statistics
: techniques summarize, describe numerical data= easier interpretation – can be graphical/involve computational analysis. Inferential statistics: techniques about decisions about statistical population/process are made based only on a sample being observed – use of probability concepts. VARIABLES:
Franco’s Justification for the 1936 Military Uprising
The Genesis of the Spanish Civil War: Franco’s 1936 Appeal
This document analyzes a political and historical text, self-authored by Francisco Franco (then General Commander of the Canary Islands), concerning the military uprising that initiated the Spanish Civil War.
The Coup of July 18, 1936
The coup d’état, launched on July 18, 1936, was primarily orchestrated by Generals Mola (Pamplona) and Sanjurjo (Lisbon). In the immediate aftermath, Franco issued an appeal directed exclusively to the military

The Symbolic Language of Peking Opera Facial Makeup
Fans of Peking Opera are familiar with its deep cultural connotations. Theatre-goers recognize the unique language conveyed through the colors, patterns, and historical background of the facial makeup. The ethics, wisdom, and philosophy of traditional Chinese culture are reflected in the makeup, indicating the specific character or role the actor is portraying.
The colors and patterns reveal whether a character is good or evil, loyal or wicked, as

Temporal Parallelism
Temporal parallelism is a clever way to speed things up in parallel computing by thinking about tasks in terms of stages or a pipeline. Instead of having one processor do everything for one piece of data before moving to the next, the work is broken down into sequential steps, and different processors work on different stages of the pipeline simultaneously.
With temporal parallelism, while one processor is loading the next image, another processor could be preprocessing the previous

Mantle Dynamics: Convection and Thermal Plumes
Convective movements consist of updrafts and downdrafts within the fluid mantle. These currents form when the fluid becomes unstable because its top is more dense and tends to sink, while the bottom is less dense and tends to rise to the surface.
Rifting and Thermal Plumes
Rifting is the rupture of a continental plate caused by the action of a thermal plume. Archipelagos of volcanic points, such as the Azores and Hawaii, are often associated with hot oceanic

Repeat 1000 times the experiment you performed in Task 1, that is rolling a tetrahedron die 10 times and computing the average. Report the average and standard deviation of the 1000 experiments. The standard deviation function in R is sd(x).
S = 1000
rolls.Avgs = vector(length = S)

Network Protocols: Electronic Mail, HTTP, TCP, UDP, and ARP
Application Layer: Electronic Mail
Electronic mail is a core application within internet networks.
SMTP (Simple Mail Transfer Protocol)
- TCP/IP based for simple text message delivery.
- Independent of message/data format.
- Utilizes information in the message header.
- Message body content is not inspected.
MIME (Multi-Purpose Internet Mail Extension)
- Enables delivery of various data types (images, video, etc.).
Basic Operation:
- Messages are created using a user agent program (mail client) containing:
- Header: Recipient
Acid-Base Equilibrium and pH Calculations
Identifying Acid-Base Problem Types
| Question Type | Problem Category |
|---|---|
| Asks if a salt solution (e.g., NaClO) is acidic, basic, or neutral | Conjugate acid-base salt classification |
| Involves a weak acid concentration and asks for the pH | Weak acid equilibrium problem (requires an ICE table and Kₐ) |
| Involves a salt of a weak acid (e.g., NaC₆H₅CO₂) and asks for the pH | Basic salt hydrolysis problem (involves a conjugate base and Kₑ) |
Core Acid-Base Concepts
Acid-Base Properties of Salts
- Strong acid + Strong base
Choosing the Right Legal Business Structure
Individual and Non-Corporate Business Structures
Sole Proprietorship (Individual Entrepreneur)
To operate as a sole proprietor, the owner must have full availability of personal assets. This structure implies total control of the company by the owner, who personally directs its management and responds to business debts incurred against third parties with all present and future personal wealth (unlimited liability).
- Taxation: The owner is taxed through Personal Income Tax (PIT).
Private Civil Partnership

Protein Quality and Biological Value
Protein quality is defined by the number, nature, and type of amino acids present. A protein has higher quality if its range of amino acids is more complete and closer to physiological needs.
Defining Protein Quality
- High Quality Protein: Contains all essential amino acids in proper proportion relative to the body’s needs.
- Limiting Amino Acid: An essential amino acid found in the smallest amount relative to the body’s requirement.
