The best stats you've ever seen | Hans Rosling

But ten years ago, I took on the task to teach global development to Swedish undergraduate students.

但十年前，我接手了一項任務，向瑞典本科生講授全球發展課程。

That was after having spent about 20 years together with African institutions studying hunger in Africa.

那是在我與非洲機構合作了約二十年、研究非洲饑荒問題之後。

So I was sort of expected to know a little about the world, and I started, at our medical university—Karolinska Institute—an undergraduate course called Global Health.

因此，人們大概期望我瞭解一些世界概況，於是我在我們的醫科大學——卡羅林斯卡學院——開設了一門名為‘全球健康’的本科課程。

But when you get that opportunity, you get a little nervous.

但當獲得這樣的機會時，你難免會有些緊張。

I thought these students coming to us actually have the highest grade you can get in the Swedish college system,

我想這些來到我們這裡的學生，在瑞典的大學評分體系中已經取得了最高分，

so I thought maybe they know everything I'm going to teach them about, so I did a pretest when they came.

所以我心想他們或許已經掌握了我要教給他們的一切知識，於是他們在入學時我做了一次預測試。

One of the questions—from which I learned a lot—was this one: 'Which country' has the highest child mortality of these five pairs?'

其中有一個問題讓我受益匪淺：‘在這五組國家中，哪一組的兒童死亡率最高？’

And I put them together so that in each pair of countries, one has twice the child mortality of the other.

我是這樣配對的：每一對國家中，一個國家的兒童死亡率是另一個的兩倍。

And this means that it's much bigger—the difference—than the uncertainty of the data.

這意味著這種差異非常大，遠超資料的不確定性。

I won't put you to the test here, but it's Turkey, which is high, as there: Poland, Russia, Pakistan, and South Africa.

我就不在這裡考大家了，但答案是土耳其（數值較高），以及波蘭、俄羅斯、巴基斯坦和南非。
