A histogram is a picture made of bars that shows how a set of numbers is spread. You first cut the numbers into ranges — bins, like 10–20, 20–30 — and each bar shows how many fell in that range. The bars usually touch, because the ranges sit next to each other on a number line.

A histogram is a picture made of barsA histogram是一種用長條組成的圖 that shows how a set of numbers is spread用來呈現一組數字的分布狀況. You first cut the numbers into ranges — bins, like 10–20, 20–30你先把數字切成一個個區間——叫做bins，像10到20、20到30 — and each bar shows how many fell in that range每一根長條就代表落在那個區間裡的數量. The bars usually touch長條通常會互相貼在一起, because the ranges sit next to each other on a number line因為這些區間在數線上是彼此相鄰的

That is the small difference from an ordinary bar chart, which often compares separate groups (cats, dogs, birds) and leaves gaps. People also use histogram as a verb: to histogram the data is to draw this kind of picture.

That is the small difference from an ordinary bar chart這就是它跟一般長條圖的小小不同之處, which often compares separate groups (cats, dogs, birds)一般長條圖常常是在比較互相獨立的類別（貓、狗、鳥） and leaves gaps而且長條之間會留空隙. People also use histogram as a verb大家也會把histogram當動詞用: to histogram the data is to draw this kind of pictureto histogram the data意思就是畫出這種圖

The English maths scholar Karl Pearson made the word in 1891. It probably comes from Greek histos, a mast (a tall post, like the bar), plus gramma, a drawn mark — though some people have said historical plus diagram; that is a later guess, not the stronger story.

The English maths scholar Karl Pearson英國數學家Karl Pearson made the word in 1891在1891年造出了這個字. It probably comes from Greek histos, a mast (a tall post, like the bar)這個字大概是從希臘文histos（桅杆，一根高的柱子，就像長條）來的, plus gramma, a drawn mark加上gramma（畫出來的記號） — though some people have said historical plus diagram雖然也有人說是historical加diagram; that is a later guess, not the stronger story但那是後來才有的猜測，不是比較站得住腳的說法

Though actually, in class the shape matters more than the origin: touching bars, one measured thing, cut into bins.

Though actually不過其實, in class the shape matters more than the origin在課堂上，形狀比字源重要: touching bars, one measured thing, cut into bins長條相連、只測一個東西、切成一個個bins
