Hi, I am still thinking about this. The following Sample Size Calculator
seems to be using the same mathematical model to estimate the size as
the one used to calculate the significance.For instance, these values
represent a significant test result:Unique visitors expected per
variation: 7500Number of expected conversions: 750Baseline CR:
10%Expected Uplift: 10%However the Adobe Sample Size calculator,
estimates a needed sample of almost the double (14748 visitors per
variation)What is the mathe...

Hi Thomas,I have created the Profile Script using the following
code:try{ var mboxParam = page.param('referidos').toLowerCase() || "";
if (mboxParam != "") { return mboxParam; } } catch(e){ // Error

Thank you for your answer Thomas, so if I understand well, I only need
to add the following code inside the profile script:
page.param(‘referidos’) == sThank you. PS: We are using the following
parameter www.oururl.com?referidos=s

Hi Thomas,Thank you for your answer. What I need is even simpler, in the
activity I want to include, all the visitors who at any moment, visit a
page which contains this parameter: ?referidos=s How can I do this? From
your answer I guess that I need to create a profile script, but I don't
know how to do it Thank you var mboxParam =
page.param('referidos').toLowerCase() || ""; if (mboxParam != "") {
return mboxParam; }

Hi!I want to create an Audience containing visitors who visit a URL
which contains a certain parameter, and once visitors visit that URL, I
want them to be a part of that audience, and not just when they are on
that URL but even when they browse out of it.How can I do this? I try to
do it using a "Site page" rule, but the only rules are "Landing page,"
"Previous page", or "Current page", and what I need is "If the page has
ever been".

Hi,Thank you for your answer Jason.Something that really worries me, is
how to explain the team who works with Adobe Target, that they should
ignore the confidence level shown, unless the sample size and number of
conversions reach the number suggested by the sample size calculator.
Would not be it easier that AT shows an alert when the sample is
sufficient? Thank you, best regards.

Hi,For instance, the following data, represents a test with 97%
confidence level:Variation A: 5000 visitors - 250 conversionsVariation
B: 5000 visitors -300 conversions (20% lift)but if we try to estimate
which is the sample needed to detect a 20% lift, when the baseline
conversion is 5%, the experiment consists in 2 variations, setting a 95%
confidence level and 80% statistical power. The calculator says that you
will need: 8,155 visitors per sample. (When the truth is that with 5000
visitors y...

Hi Chintan,Thank you for your answer, it helps a lot.If I understand
well, we only should look at the confidence level when the sample reach
the minimum sample estimated by the calculator. My question then is, Why
target is telling us that there is a 99% confidence level, when the
sample isn't enough?Thank you, best regards.

Thank you for your reply RohitThe point is that the sample calculator
always over estimates the amount of traffic needed to reach conclusive
results, this also happens using others size calculators.

Why the sample size calculator over estimates the sample needed? With
fewer visitors than the estimated, the results are conclusive.For
example:80% power, 95% Confidence level, baseline conversion of 10%, 2
offers, and 1000 daily visitors, the calculator says that you will
need:a sample size of 14,748 visitors to detect a lift of 10%. However,
with 10,000 visitors per offer, you can detect a lift of 10% with a
98,89% Confidence Level. Thank you in advance for your help.
