"A/B Test Calculator" tell you what percentage are statistically significant of your A/B test results.
The A/B test, it is mainly carried out in the Internet marketing, generic name of the test for the policy decision.
++ The A/B test in the web site ++
The A/B testing of web sites, by altering a portion of the web site, consider which of the parts "A" and "B" in the web sites in comparison is superior in terms of usability.
++ The A/B test in Internet advertising ++
In the A/B test in Internet advertising, by separating out the creative evenly, it compares either of ad you want to compare "A" and "B" raises more achievements, to determine the adopted advertising.
++ The A/B test in landing page optimization ++
A/B testing of landing page optimization, the landing destination page of Internet advertising is more prepared, by distributing the landing destination, and compares whether the landing page "A" and "B" is increased more outcomes employed It will determine the landing page to be.
The following is a quote from "The A/B Test: Inside the Technology That’s Changing the Rules of Business" (http://www.wired.com/2012/04/ff_abtesting/).
The testable web is so much safer. No choices are hard, and no introspection is necessary. Why is B better than A? Who can say? At the end of the workday, we can only shrug: We went with B. We don’t know why. It just works.
In statistics, confidence intervals can be used to express the degree to which sample results are reliable.
Confidence intervals are often stated in terms of a percentage like 90% or 95%. When the sample or population distribution is the Normal (bell-shaped) distribution, the confidence intervals can be represented as a number of standard deviations (σ) above or below the sample mean (μ).
Moving the slider beneath the graph will vary the confidence intervals from 50% to 99%. Additionally, you may choose the two-tailed confidence intervals or the one-tailed interval by tapping the button beneath the slider.
In this application, you may chose the standardized Normal distribution with μ=0.0 and σ=1.0 or some other values for mean and standard deviation.
