I created a ranking type question with 6 answers (question code Q2).

When I go to the Statistics section and include that ranking question to review, I get 4 tables -- like Q2[1], Q2[2], Q2[3], Q2[4].

I don't understand how to interpret these tables (Ranking 1, Ranking 2, Ranking 3, Ranking 4). The answers are listed in the same order in each, but with different counts and %'s.

What does this mean? How I can tell what was ranked highest overall? Or what the overall ranking of each answer was?

Can you show a screenshot of what you are seeing?

Hi

I have the same question. I get several and different results from the same ranking question on expert mode.
Attached a screenshot.

Thank you.

The ranking type question creates a data column for every possible rank. So it essentially becomes a series of questions. In the data you will see all of the answers ranked in position 1 in one column , all of the answers ranked second in another column, and so on. This leads to the different charts for each possible rank position.

OK. And which answer is the most common or frequent? Would that be the first table?

First: The LimeSurvey statistics is just to have a quick glance at the results. Here you see which objects were ranked first with which frequency, or ranked last. All further calculations you will do in your statistic tool.

And which answer is the most common or frequent? Would that be the first table?

There is no simple answer.
Let me explain by ranking products.
You get this data table.

The first column shows the products ranked first.
You see "Product 3" is ranked first 3 times, more than all others.
But is it the best product? It is ranked last 3 times, too. So the opinion about this product is very ambivalent.

To analyze your results, this way to display the ranks is not the best.
To find out the overall rank of each product you have to calculate the middle rank, the mean of the ranks.
So in your analyzing tool you should restructure the table to

The columns now show the rank of one product.
Now you can calculate all statistical tests to find out which one is ranked best, is there a significant difference between the products
As shown you might get the same mean for several products
There are products which are either loved or hated (many times first place, but also many times last place)
Other products are more or less boring, uninteresting (ranked in the middle)
Now you may calculate the standard deviation of the product ranks.
Here you see that the opinions about "Product3" are more equivocal than about "Product2"

And even if you see a difference ("Product1" vs. "Product2") this might be of no significant meaning.
The t-test shows this.
