Parametric Inference Fundamentals

The probability distribution of the population under study is known, except for a finite number of parameters. Its goal is to estimate those parameters. Examples include the T-test and ANOVA.

Non-Parametric Inference Basics

The distribution of the population is not known. It is used to test the assumptions of parametric methods, for example, to check if the population distribution is normal.

What is a Statistic?

A random variable function of the sample that does not depend on the unknown parameter.

Understanding Estimators

A statistic whose values are acceptable for estimating an unknown parameter.

Unbiasedness in Estimation

We do not allow systematic overestimation or underestimation of the parameter, which would result... Continue reading "Statistical Inference & Hypothesis Testing Concepts" »

Understanding Cool Jazz and Hard Bop

Map Generalization

Types of Symbols

• Line Symbols: Represent real-life objects with a linear path.
• Point Symbols: Represent objects occurring at a single point on Earth's surface using a dot.
• Area (Polygon) Symbols: Represent real-life objects spread over Earth's surface using geometric shapes.

Generalization Techniques

Reality contains too much information for a single 2D map. Generalized geometry and content make a map useful. A good map suppresses less important information to highlight what needs to be seen.

• Selection: Only relevant line, point, and area features are chosen.
• Classification: Grouping similar features and using a common symbol to represent them.
• Simplification: Reduction of unnecessary detail.
• Smoothing: Smoothing out abruptly joined

The Manager,
17 Manor Drive, Castletown, Co. Longford. June 14th, 2008

Jeans World,
Castletown, Co. Longford.

Dear Sir/Madam,

On Friday, June 9th, I bought a pair of Levi jeans in your shop. When I took the jeans home, I noticed two buttons were missing. I went back to the shop with the receipt and asked the shop assistant to exchange the jeans for a pair that were not damaged. She refused. She said the jeans were perfect when they were sold and said they had been damaged since leaving the shop. A quick look would have shown that buttons had never been sewn on and that it was most likely a fault that had happened in the factory.

I insist on my rights as a consumer and wish for an exchange or my money back. Please contact me at the above address as... Continue reading "Jeans Complaint, Job Application & Internet Shopping" »

The Crucial Role of English Proficiency Today

In past years, many people could build a career with only basic English knowledge. However, things have changed, and now a high level of English is often required for any career or job. For example, in Spain, to pursue a career, one must pass a selectividad exam, and English is one of the required subjects. Therefore, if you don't speak English, it will be very difficult to establish a career.

Also, in Spain, students can obtain Becas Erasmus (Erasmus scholarships) to travel to another country and study their chosen field for a year. Knowing English also allows you to study or work in English-speaking countries like England, which is a very interesting country. Furthermore, having a career path may...

Acid Value Determination in Oils: Principle and Procedure

Here's an explanation of the principle and procedure involved in determining the acid value of an oil sample:

Principle

The acid value of an oil sample is a measure of the amount of free fatty acids present in the oil. The principle of the acid value determination is based on the reaction between the free fatty acids in the oil and a strong base, such as potassium hydroxide (KOH). The reaction is as follows:

RCOOH (Free Fatty Acid) + KOH → RCOOK (Potassium Salt) + H₂O

Procedure

Here's the step-by-step procedure for determining the acid value of an oil sample:

1. Apparatus

• 250 mL Erlenmeyer flask
• Burette
• Pipette
• Volumetric flask
• Phenolphthalein indicator

2. Reagents

• Potassium hydroxide (KOH) solution
