Here's a not too well-known instance of the use of $\varepsilon$ in mathematics: One somewhat well-known transformation for accelerating the convergence of a sequence is the Shanks transformation (after Daniel Shanks, who is probably more well-known for his number-theoretic contributions).
Thereâs no set way of creating a test plan, but there are common suggestions on what to include. Test plans donât need to be done a certain way, but if youâre new to writing test plans, the IEEE 829 is a good place to start. This standard for test plan documentation is used for software and system testing. It is a good âtemplateâ for writing your own test plan documents.
The first step in setting up an effective A/B test is to decide what youâll test. While you may want to test more than one thing, itâs important to only test one thing at a time to get accurate results. Things you might consider testing include: Call to action (Example: âBuy Now!â vs. âSee Plans & Pricingâ)
