What is Key Analysis

Key analysis allows you to calculate statistics based on the answers your respondents have provided. Five 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.
Std. Deviation This is a measure of the spread of the data - how widely, or narrowly, the results are distrubuted. A large number means a wide spread of data.
Satisfaction Rate The satisfaction rate as a percentage. Click here for more details on the calculation of satisfaction rates.
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.
