To teach you how to do this, I will give you a few examples from the Liver Flush Survey. We are going to test a few hypothesis in order to learn how to filter accumulated survey data.

Hypothesis: People who do not complete a thorough bowel cleanse prior to flushing are more likely to experience problems during or after a liver flush.

To test this hypothesis, the first thing I am going to do is to select all people who have completed a thorough bowel cleanse.  I want to find out what is the level of problems associated with those who completed a thorough bowel cleanse, and then I am going to compare those data with those who haven't done any bowel cleansing.

Let's search for all people who completed a thorough bowel cleanse. It is easy cause  a thorough bowel cleanse is one of the main questions.  Let's go to that question page:

Here it is: http://curezone.com/faq/p/r.asp?a=28,571,2826&s=21&u=50

Results of that question:

So, we have 32 people (58%) who completed a thorough bowel cleanse before flushing. To continue working with only those 32, you now click on 58%  which is actually a clickable link.

That link brings you to a page that lets you select a second question.
We are going to select this one as our second question: Major Risks? Major symptoms and problems encountered during a liver flush:
http://curezone.com/faq/p/r2.asp?a=28,571,2826&s=21&u=50&o=10352&u2=4

Results of that question:

As we can see, 22% of those who completed a thorough bowel cleanse encountered some major problems.

Now, we are going to repeat the same process, but this time we will select those who did not complete a thorough bowel cleanse.

To continue working with only those 15 who selected NO, you now click on 27% .

That link brings you to a page that lets you select the second question: Major Risks? Major symptoms and problems encountered during a liver flush:
http://curezone.com/faq/p/r2.asp?a=28,571,2826&s=21&u=50&o=10351&u2=4

Results of that question:

As we can see, 27% of those who completed a thorough bowel cleanse encountered some major problems.

So, the question is:  Is there a significant difference between 22% compared to 27%?

Keep your feet on the ground, and remember that at time of writing this, very few people actually answered all survey questions, so we have only 3 people who encountered major risks and 8 who didn't.

Those numbers, 3 and 8 are far too small to draw any valid conclusion.
The most important thing here is that you have now (I hope) learned how to filter survey data.

Next hypothesis that you should test:

Hypothesis: People who do not complete a thorough bowel cleanse AND people who do not complete a thorough parasites cleanse are more likely to experience problems during or after a liver flush.

Testing this hypothesis asks for filtering data even deeper.

First we select all people who have completed a thorough bowel cleanse:
Here they are: http://curezone.com/faq/p/r.asp?a=28,571,2826&s=21&u=50

Then we click on 58% select the second question: Parasites Cleanse:
http://curezone.com/faq/p/r2.asp?a=28,571,2826&s=21&u=50&o=10352&u2=53

So, there are 14 people (78% ) who completed both parasites cleanse and bowel cleanse.

Now, we click on  78%  and select the third question: Major Risks:
http://curezone.com/faq/p/r3.asp?a=28,571,2826&s=21&u=50&o=10352&u2=53&o2=10766&u3=4

This is the result: 79% did not suffer any major symptoms or problems.

We repeat the same process, but this time we filter and find those that have not completed neither of cleanses:
http://curezone.com/faq/p/r3.asp?a=28,571,2826&s=21&u=50&o=10351&u2=53&o2=10765&u3=4

This is the result. 100% of those who never competed a Bowel Cleanse and never completed a Parasites Cleanse NEVER suffered major problems or symptoms.

Of course, at time of writing this, number of people who never completed cleanses is 10. That number can not be considered as a representative number for all the people who are flushing. Let's wait until we have 100 people before we try to draw any conclusion.

If you have any question or a suggestion related to data filtering, please ask that question inside Survey Discussion Forum.

What you can not do?

You can not select any of the Standardized Questions as your first question.  Standardized Questions must be selected as your last question, when filtering data. These are the limitations of the software.

You can select maximum 3 questions. So far, software allows max of 3 questions.

To exercise, try to test next hypothesis:

1: People who suffered constipation before flushing are more likely to encounter problems during a liver flush.

2: People who suffered constipation before flushing don't drink enough water. (Water intake is one of the standardized questions and must be selected as a last question.)

3: Women are more likely to encounter problems during a liver flush then men.  (Gender is one of the standardized questions and must be selected as a last question.)
