Show or hide statistics

For Number and Allocation questions, you can display statistical values calculated from participants' numeric responses.

Open the standard survey report.

1. On the report toolbar, click Statistics.
2. Select or clear the statistics you want to show or hide.

   By default, mean and median are displayed.

   The following table describes the statistic options available.

   Statistic	Description
   Mean	A value derived from adding all the values in a group of values, then dividing by the number of values in the group. For example, 2, 3, 3, 5, 7, and 10 equal 30. To find the mean, you would divide 30 by 6, the number of values in the group. The mean value in this case is 5.
   Median	The value that occurs in the middle of a group of values, with half that group being larger than the median and half of that group being smaller than the median. If there is an even number of values in the group, the average of the two middle values is used as the median. For example, the median of 2, 3, 3, 5, 7, and 10 is 4.
   Minimum and Maximum	The smallest and largest values in a group of values.
   Standard Deviation and Error	Standard deviation indicates variability from the mean. A low standard deviation indicates the data is clustered closely around the mean. A high standard deviation indicates that data is spread out on either side of the mean. Standard error is a value that represents the standard deviation of the sampling distribution associated with the estimation method.
