This article needs to be renamed to "Alternative hypothesis", as "alternate" is the wrong word. Melcombe (talk) 16:55, 19 March 2008 (UTC)[reply]

Support as common usage. I do not believe this is an Anglo-American problem. Septentrionalis PMAnderson 17:52, 28 March 2008 (UTC)[reply]
In my experience alternative is more common, probably in part due to lowers ambiguity outside America. Knepflerle (talk) 12:57, 31 March 2008 (UTC)[reply]
"Alternative" is about 9 times more common:
- 369 articles with "alternative hypothesis"
- 40 articles with "alternate hypothesis"
It is also more correct. Thunderbird2 (talk) 18:27, 31 March 2008 (UTC)[reply]

Inappropriate image[edit]

In a two-tailed distribution, the tails are the light-yellow regions of the graph, on the right. Imagine that a container of margarine has been filled with 250g, but within an error + or - 2.5g. The container is to be rejected for sale if the error exceeds 2.5g.

This image appears in the article, but it seems to be not relevant to this context of hypothesis testing. There is no hypothesis, and there is no data set other than the single data point of this one container. So I'm going to delete the image. Loraof (talk) 17:29, 21 February 2017 (UTC)[reply]

Potentially wrong example[edit]

I think that the null hypothesis in the example is not complete. It states "there is no change in quality between the first and second halves of the data" and the alternative is "the quality is poorer in the second half of the record". What if the quality turns out to be better? Shouldn't the null specify something like "Quality 2 ⩾ Quality 1" since the alternative is "Quality 2 < Quality 1"?
