## Analysis Menu - Statistics

For **number** and **weighted score** questions, EZSurvey can calculate statistics based on your database. If you wrote **single choice** questions, you can change them to **weighted score** questions for reporting purposes. If you wrote **write-in text** questions that only contain numbers, you can change them to **number** questions for reporting purposes.
- Have the survey file opened (see how to open EZSurvey project).
- Make sure the path to the database that stores the survey data is valid.
- Select
**Database View database** to see if the records in the database are available or not. If the records are available, you can continue. If they are not, you may need to stop here and check to see if the survey data has been collected correctly or not. (see the topics below for more information)
- Select
**Analysis Statistics**. The *Statistic view window* opens. You can see the statistic results based on the data in your database.

Standard operations and their descriptions:

*Average* - Average numeric value
*StdDev* - Standard deviation is a measure of the dispersion of the answers. If the standard deviation is small (relative to the entire range of responses), then most of the answers are near the average value. If the standard deviation is large, then the answers are more spread out.
*Min* - Minimum value (zeros are included)
*Max* - Maximum value (zeros are included)
*Count* - Number of records considered for analysis
*Sum* - Total of all answers

When EZSurvey calculates statistics, here's what values it considers:

For **number** questions, any non-zero numbers are counted. Blank responses are treated as zero and are ignored.

For **weighted score** questions, the numeric value of the *response code* is counted. Zero and non-numeric values are ignored.

Values that are ignored are **not** included in the statistics table. Because people may answer some questions but not others, the counts for each question may vary.
