What are Basic Statisics?

Basic Statistics allows you to calculate statistics based on the answers your respondents have provided. Seven different figures are provided in the Analysis table.

Mean This is the "Average" value of the data in the sense that most people usually use the word. The total of all collected values, divided by the number of values.
Std. Deviation This is a measure of the spread of the data - how widely or narrowly the collected values are distrubuted. A large number means a wide spread of data. Because of the calculation used, it's less affected by small numbers of outlying values at the ends of the data set so is often preferred as a measure of data spread to a simple calculation of "Range" (which is Maximum - Minimum).
Satisfaction Rate The satisfaction rate as a percentage. Click here for more details on the calculation of satisfaction rates. This is only shown on some question types.
Variance Like Standard Deviation, this is a measure of data spread. In fact, it's the square of the Standard Devation.
Std. Error A measure of how accurately your calculated mean (based on a sample) reflects the true mean of the population. The smaller this number is, the more accurate your mean.
Minimum The lowest value recorded in any response.
Maximum The highest value recorded in any response.
