 Numeric Questions

This type of question is used to capture an exact numeric answer from the respondent.

Only whole numbers (no fractions or numbers to the right of the decimal point) are allowed.  Mode, median, mean and standard deviation analysis are provided for all numeric questions.  Any answer between 1 and 9,999,999 is valid.  0 (zero) is a non-response, and is not stored or counted as a valid answer.

Statistical Analysis

Here is a brief overview of the analysis that is performed on Numeric responses:

Mode - The category that most responses fall into. If you have five answers; 4, 2, 3, 4, 1; the mode would be 4, as two of the five answers (the greatest number) are 4.

Median - The value at which half the numbers are above, and half the numbers are below.  For example, consider the answers 1, 2, 4, 5. The median is 3, as half the answers (two of them) are below 3, and the other half are above 3.

Mean - What is commonly referred to as an average.  Essentially, all the valid numeric responses are added together, and the sum total is divided by the number of responses.  For example, the mean of 1, 4, 6, 1 is 3 (1 + 4 + 6 + 1 = 12, divided by 4 responses).

Standard Deviation - Now we're getting into some complicated, pocket-protector, slide-rule mumbo-jumbo number-crunching! Standard deviation is an indication of how tightly grouped together the answers are for the mean.  For example, consider two sets of numbers: 5, 6, 5, 5, 4 and 1, 2, 5, 9, 8.  The mean of both sets is 5, but in the first group almost every number is very close to 5 (within 1 number away). In the second group, almost every answer is very far from 5 (generally 3-4 numbers away).  The higher the standard deviation, the wider the range of answers in a dataset.

This might be more numerical analysis than you will ever use, but it's nice to know if you want to know what the average of all answers is, or what the mid-point is, or how spread-out the responses are, you now have the tools to determine that with ComQuest!
