Business letter


Business Letter
Writing a professional, polished business letter or business email is easy once you know the basics. Most business letters are written in a simple format that is easily adapted to any company’s needs, and business email follows a similarly simple format. Read on to learn more about how to make your business correspondence look its best.
How to Write a Business Letter: The Basics
A business letter always contains a few standard parts:
       ·         The date
       ·         Information about its sender and recipient
       ·         A salutation
       ·         A body consisting of a few concise paragraphs
       ·         A closing
       ·         The sender’s signature
       ·         The sender’s typed name, title, and contact information
       ·         A list of enclosures, if necessary
Company address:
If your company has letterhead, you can use this instead of typing out the information. If not, your company’s address should appear either right or left justified at the top of the page. Write out each word in the address instead of using abbreviations. For example:
ABC, Inc.
400 Leafy Lane
Los Angeles, California 90002
Date:
Write the date out rather than abbreviating with numbers only. For example, “March 1, 2015” or “1 March 2015.” The date should be left justified and should be positioned two or three lines above the recipient’s address.
Recipient’s name and address:
Add the recipient’s name, their title if known, and their address. Write out each word in the recipient’s address. This information should be left justified a few lines above the salutation. For example:
Mr. Jack Reacher
Merchandising Manager
Craft Supply Provider, Inc.
602 Spinner’s Road
Los Angeles, California 90001
Salutation:
Choose your salutation based on whether you know the person to whom you are writing, how well you know them if so, and the relationship’s level of formality. A salutation is more than a simple greeting; it is an indicator of respect. There are several options to use depending on the situation:
       ·         To Whom It May Concern: Use this generic greeting only if you don’t know whom you are specifically addressing.
       ·         Dear Sir / Madam: This is another generic greeting that should only be used if you don’t know who will be reading your letter.
       ·         Recipient’s Title and Last Name: This is a widely accepted method of incorporating a salutation into business correspondence. Examples include: “Dear Dr. Jamison” or “Dear Professor Williams.” The salutations “Dear Mr. Smith,” “Dear Ms. Kennedy,” and “Dear Mrs. Rollins” are additional examples of this kind of greeting.
       ·         Recipient’s First Name: Use this only if you and the recipient already enjoy an informal relationship. An example is: “Dear Maria.”
       ·         The Recipient’s Whole Name: If the recipient does not have a title and you are unsure of their gender, you should greet them using their entire name. For example: “Dear Pat Brown.”
Always add a comma after a salutation, unless you are using “To Whom It May Concern,” in which case a colon is appropriate.
Body:
The body of your business letter should contain a few concise paragraphs that convey your message clearly. Strike the right tone by avoiding lengthy, meandering sentences and getting straight to the point. If you are not sure how to start, consider using “I am writing you regarding…” as the opening phrase.
Your reader will get the best impression when your meaning is crystal-clear. You should explain your position using as few words as possible an. At the same time, feel free to be conversational if it is appropriate. Business correspondence should be friendly and helpful if possible.
Summarize your points clearly in the last paragraph and outline your expectations or your planned course of action. This is a suitable place to mention that the recipient may contact you with concerns or questions. Be sure to thank the recipient for his or her attention to the letter or to the matter at hand.
Closing:
Like its salutation, a business letter’s closing is an indicator of respect that should reflect the formality of your relationship.
        ·         Formal Closing: A closing such as “Sincerely,” “Yours sincerely,” “Respectfully,” “Yours Truly,” “Regards,” and “Cordially” are suitable for all types of business correspondence.
        ·         Informal Closing: Less formal closings such as “Best wishes,” “Warm regards,” “Best,” “Thank you,” and “All the best” are still professional, but are best for letters to people with whom you enjoy an ongoing, friendly business relationship.
Use a comma after your closing, no matter which you choose. Left justify the closing.
Signature:
Leave about four lines of text empty so you have room to sign your name. Use blue or black ink for a clean, professional look.
Sender’s typed name and contact information:
Type your name, then add your title on the next line. Skip a line, then type your telephone number. On the next line, type your email address. For example:
Terry Brown
Vice President of ABC, Inc.

223-555-1212
t.brown@abc-inc.com
This information should be left justified.
Enclosures (if applicable):
If you plan to enclose anything with your business letter, type the word “Enclosures” followed by a colon and make a note that tells the recipient what else to look for in the envelope. For example:
Enclosures (2): brochure, flyer
Enclosures: two brochures
This information should be left justified and should be positioned a few lines below your contact information


Full Block Format

The Full Block business letter layout is the easiest to format. Here everything starts at the left margin, in the fact that no tabs are needed. This style is efficient and businesslike. No wonder it has become so popular.

Setting up a block style letter is quite simple, since every line starts flush with the left margin.

To format a business letter in block style:

1. Type all lines beginning at the left margin.

2. Center the letter vertically, then type the date.

3. After the date, press Enter 4 times and type the inside address. Leave 1 space between the state and the ZIP code.

4. After the inside address, press Enter 2 times and type the salutation.

5. Press Enter 2 times and begin the body of the letter.

6. Single-space the body, but press Enter 2 times between paragraphs.

7. After the last paragraph, press Enter 2 times and type the complimentary closing.

8. Press Enter 4 times and type the writer's name and address.

Semi-Block Format

The Semi-Block style's return address, date, complimentary closing and the signature line are at the center of the paper, or rather to the right of center. Everything else is flush with the left margin. Most of us are comfortable with this business letter layout as it has traditionally been the most commonly used. 

Semi-block style is characterized by certain parts of the letter being offset. This is usually the header, where you put your name and address. Also, it includes the date and the signature line at the bottom of the letter. These two elements should be aligned with one another, though they are offset from the rest of the letter.

Explain the Differences Between TOEFL & TOEIC

The TOEFL (Test of English as a Foreign LanguageTM) measures the test-taker's ability to function in an English-speaking academic environment. The target test-taker for the TOEFL is a candidate for higher education in an English-speaking country.
The TOEIC (Test of English for International CommunicationTM), on the other hand, measures the ability to function in a general work environment. This test is used in nonacademic settings as a measure of the ability of a current or potential employee to communicate effectively in English in a variety of business settings and situations.

Test Formats

The TOEFL is a four-section test that includes sections for reading, listening, speaking and writing. It is taken exclusively on the computer.
The TOEIC is broken into two separate but complementary exams: the Reading and Listening Test, which is a paper-and-pencil test, and the Speaking and Writing Test, which is taken on a computer. The exams are broken up in this way so potential employers can choose to measure an employee's reading and listening or speaking and writing skills only, or all four language skills. The Reading and Listening Test will take about two-and-a-half hours to complete, and for the Speaking and Writing Test, the speaking section will last about 20 minutes, and the writing section will take 60 minutes to complete.

Test Content

In the TOEFL, the test-taker is measured on his ability to function in an academic environment. In this regard, the vocabulary on this test is academic in nature and is similar to the vocabulary used in college text books. The topics of the reading and listening passages are similarly academic. You may read a passage on bird migration, for example, or listen to a lecture from an economics course.
 The TOEIC, on the other hand, measures the test-taker's ability to function in a business environment. Topics may range from dining out in a restaurant to presenting in a budget meeting.


Test Scores

On the TOEFL iBT, the maximum possible score is 120 -- 30 points for each of the four sections. There is no "passing score" and colleges and universities will have their own requirements for admission, which test-takers can find information about through the admissions office.
 The TOEIC Reading and Listening test gives the test-taker a score of 10 to 990, which corresponds to bands in the Common European Framework measure of English proficiency. A test-taker will receive scores of zero to 200 for the Speaking and Writing Tests separately, again which corresponds to the CEF standards of English-language proficiency measurements.

Who takes the test

          The TOEFL
     ·        Students in the academic track of English language programs/schools
     ·        Students in colleges or universities that have a language requirement
     ·        Applicants to scholarship and exchange programs.

The TOEIC
     ·        Employees in international corporations
     ·        Job applicants
     ·        Students in business, vocational, and trade schools, community colleges
     ·        Students in the business track of English language programs/schools.

Other uses

The TOEFL
     ·        For English language programs/schools, especially business-track students
Ø Placement test
Ø Assessment of progress from beginning to end of course
Ø Measurement of program effectiveness
Ø Exit test
     ·        Practice for secure TOEIC
     ·        Professional credential


The TOEIC
     ·        For institutions of higher education
Ø To fulfill language requirement or graduation requirement
Ø To screen for scholarship and exchange programs
     ·        Practice for TOEFL or other multiple-choice tests
     ·        Professional credential

Example Question TOEFL

In the Sentence Completion questions, one or more words are left out of each sentence. Under each sentence, you will see four words or phrases. Select the one word or phrase that completes the sentence correctly.
1. Juan quietly watches the bird _____ perches on his windowsill so he won't scare it away.
(A) that
(B) who
(C) which
(D) whom

Answers
The correct answer is (A). The correct pronoun to use is "that" because the pronoun is referring to a specific bird. "Who" and "whom" are only used to refer to people. "Which" is used to set off extra or unnecessary information.

Example Question TOEIC

Ms. Monica Eisenman
555 King Street
Auckand
New Zealand

Dear Ms. Eisenman:

I am _ _ _ _ to confirm our offer of part-time employment at Western Enterprises, in your role
   (A) pleased
   (B) pleasing
   (C) pleasant
   (D) pleasure

Answers
(A) (B) (C) (D) The correct choice is "pleased"

DISTRIBUSI PROBABILITAS KONTINU

Diskrit dan Kontinu

Kedisktritan suatu sistem dapat dilihat dari perubahan keadaan sistem dari waktu ke waktu. Jika perubahan keadaan yang terjadi hanya pada waktu tertentu, bukan pada setiap titik waktu, maka dikatakan sistem diskrit. Dalam hal lain dikatakan sistem kontinu.
Dalam membuat suatu simulasi, harus sesuai dengan perilaku sistem. Dari sistem diskrit, akan dijumpai variabel diskrit, untuk sistem kontinu, akan dijumpai variabel kontinu. Contoh mendapatkan variabel diskrit dengan menghitung jumlah produk cacat, jumlah sumber daya manusia, jumlah mesin yang dibutuhkan. Contoh mendapatkan variabel kontinu dengan menggunakan alat ukur, berat kemasan, tekanan udara, waktu antar kedatangan, waktu proses.
Dari variabel diatas didapatlah data pengamatan, tidak hanya sifatnya yang harus kita ketahui, tetapi pola penyebarannya juga harus kita ketahui, maka kita pelajari mengenai pola distribusinya. Agar simulasi yang kita lakukan nantinya sesuai dengan keadaan yang sebenarnya.

Pendugaan Pola Distribusi

Kita perlu mengetahui pola distribusi dari data pengamatan, sehingga pada saat melakukan simulasi nantinya, pola distribusi variabel acak yang diambil akan sesuai dengan pola distribusi data yang sebenarnya.
Ada beberapa cara yang bisa ditempuh :
  1. Ringkasan Statistik
a.    Beberapa distribusi dapat dikarakteristikan paling tidak oleh ringkasan statistik datanya. Dari ringkasan ini dapat diketahui keluarga distribusinya. Nilai-nilai pemusatan merupakan besaran statistik yang cukup penting guna menduga keluarga distribusi. Mean ( ) dan median ( ) misalnya, pada distribusi kontinu jika nilainya sama, maka dapat dipastikan bahwa kurva distribusi berbentuk simetris.
b.     Koefisien varian ( ) juga mempunyai peranan yang penting dalam menduga keluarga distribusi. Untuk nilai koefisien varian 1(satu) maka dapat diduga data berdistribusi eksponensial, jika lebih besar atau lebih kecil dari satu maka dugaan mengarah kepada ditribusi Gamma.
c.    Untuk distribusi diskrit, maka dari nilai rasio lexis () dapat diduga distribusinya. Jika nilai rasio lexis = 1 dugaan berdistribusi poisson, Jika nilai rasio lexis < 1 dugaan berdistribusi Binomial dan  Jika nilai rasio lexis > 1 dugaan berdistribusi binomial negatif.
d.    Kelandaian distribusi (Skewness)
Rumus Skewness = . Untuk distribusi simetris, skewness bernilai 0(nol), jika, skewness > 0 distribusi akan menjulur kekanan dan sebaliknya ke kiri. Misal nilai skewness = 2 berarti data berdistribusi eksponensial.

  1. Histogram dan Grafik Garis
Dari bentuk histogram data, maka memcerminkan pola distribusinya.

Distribusi Kontinu
Distribusi Kontinu memiliki sifat kontinu, data yang diamati berjalan secara berkesinambungan dan tidak terputus.
