高校数学(用語)「四分位偏差」

高校数学(用語)「四分位偏差」

★四分位偏差(quartile deviation)

四分位範囲の半分の値のこと。


四分位範囲は、第3四分位数と第1四分位数の差であり、箱ひげ図の「箱」のサイズだから、「箱」の真ん中が四分位偏差。ということができます。

四分位範囲を問う問題はそれほど出ませんが、一応覚えておきましょう!


データの分析の考え方・解き方の習得に活用してください。好評です!

■ 問題

2021年大学入試共通テスト第2日程より

第5問

You are going to give a talk on a person you would like to have interviewed
if they were still alive. Read the following passage about the person you
have chosen and complete your notes.

[Vivian Maier]

This is the story of an American street photographer who kept her passion
for taking pictures secret until her death. She lived her life as a
caregiver, and if it had not been for the sale of her belongings at an
auction house, her incredible work might never have been discovered.
It was 2007. A Chicago auction house was selling off the belongings of
an old woman named Vivian Maier. She had stopped paying storage fees, and
so the company decided to sell her things. Her belongings--mainly old
photographs and negatives--were sold to three buyers: Maloof, Slattery,
and Prow.
Slattery thought Vivian's work was interesting so he published her
photographs on a photo-sharing website in July 2008. The photographs
received little attention. Then, in October, Maloof linked his blog to
his selection of Vivian's photographs, and right away, thousands of people
were viewing them. Maloof had found Vivian Maier's name with the prints,
but he was unable to discover anything about her. Then an Internet search
led him to a 2009 newspaper article about her death. Maloof used this
information to discover more about Vivian's life, and it was the
combination of Vivian's mysterious life story and her photographs that
grabbed everyone's attention.
Details of Vivian's life are limited for two reasons. First, since no
one had interviewed her while she was alive, no one know why she took so
many photographs. Second, it is clear from interviews with the family she
worked for that Vivian was a very private person. She had few friends.
Besides, she had kept her hobby a secret.

Vivian was born in 1926 in the United States to an Austrian father and
a French mother. The marriage was not a happy one, and it seems her mother
and father lived apart for several years. During her childhood Vivian
frequently moved between the US and France, sometimes living in France,
and sometimes in the US. For a while, Vivian and her mother lived in New
York with Jeanne Bertrand, a successful photographer. It is believed that
Vivian became interested in photography as a young adult, as her first
photos were taken in France in the late 1940s using a very simple camera.
She returned to New York in 1951, and in 1956 she moved to Chicago to work
as a caregiver for the Gensburg family. This job gave her more free time
for taking photographs.
In 1952, at the age of 26, she purchased her first 6 × 6 camera, and
it was with this most of her photographs of life on the streets of Chicago
were taken. For over 30 years she took photos of children, the elderly,
the rich, and the poor. Some people were not even aware that their picture
was being taken. She also took a number of self-portraits. Some were
reflections of herself in a shop window. Others were of her own shadow.
Vivian continued to document Chicago life until the early 1970s, when she
changed to a new style of photography.
An international award-winning documentary film called Finding Vivian
Maier brought interest in her work to a wider audience. The film led to
exhibitions in Europe and the US. To choose the photographs that best
represent her style, those in charge of the exhibitions have tried to
answer the question. "What would Vivian Maier have printed?" In order to
answer this question, they used her notes, the photos she actually did
print, and information about her preferences as reported by the Gensburgs.
Vivian was much more interested in capturing moments rather than the
outcome. So, one could say the mystery behind Vivian's work remains
largely "undeveloped."

「高校英語 和訳↔英訳 特訓問題集B仮定法、強調・倒置、接続詞」P.82より It shouldn't be...

9月に発売した新刊「高校英語 和訳↔英訳 特訓問題集B仮定法、強調・倒置、接続詞」から1問ご紹介します。





[1st STEP Question]
それぞれの英文を、意味のかたまりごとにスラッシュで区切り、和訳してください。

56 It shouldn't be long before the plum blossoms come out.


[words]
plum:梅、プラム blossom:花
come out:咲く、出る



まず、1st STEPでは、スラッシュで区切り、各部分の和訳をします。


[1st STEP Answer]
46 As the girl sat / with the dog, / her fear vanished.
  その少女が座ったとき / その犬と共に / 彼女の恐怖は消えた



[2nd STEP]
2nd STEPでは、1st STEPを活用して、つなげて1文にします。
(英文・和訳は省略します)


[3rd STEP Question]
指示に従って書き換えてください。
56 It shouldn't be long before the plum blossoms come out.
  (接続詞を使わずだいたい同じ内容に)


[Hint]
56 「すぐに」という意味にすればOK!


[3rd STEP Answer]
(解答の英文と和訳は省略します)


3rd STEPでは、主に書き換え問題を掲載しています。
そして、4th, 5th STEPで最初の文の英訳をしていきます。


[4th STEP]
スラッシュで区切られた日本語を英語に直してください。

56 それは〜の前は長くないはずだ / その梅の花が咲く

→56 It shouldn't be long before / the plum blossoms come out.


[5th STEP]
和文英訳をしてください。

(和訳と英文は省略します)


このように、「英文のスラッシュリーディング→和訳→文法問題→英訳」という手順で段階的に進んでいくので、比較的難易度の高い英文でも、無理なく「和訳↔英訳」ができるようになっています。
この本を一通り終えれば、英検2級程度なら楽勝!ですね!


他にも多数の問題を掲載しています。ぜひ皆さんも「和訳→英訳」特訓していきましょう!
