Broadband Speed Stats – Check the sample Size

Since John has returned from Uni our conversations have covered the statistical significance of some announcements in the news.

This morning has seen the 2 extremes; the CERN claim that their Higs-like particle is confirmed by their 5 Sigma test. It fits the match with a 99.9997% probability so they can claim their discovery.

I spotted that our internet was running better this morning and ran a couple of download tests including the one by uSwitch, below. This confirmed that the download speed had doubled earlier that BT’s planned date for our local exchange’s upgrade.

This single test now has my provider PlusNET as the fastest provider for our street on uSwitch, see below, as uSwitch is designed to encourage switching. What it should do is to trigger some new test data for BT and the other providers that will also have doubled as a result to the common equipment upgrade.
uSwitch do correctly include the sample sizes in a smaller font.

ADSL Speeds biassed by a single reading.
