The “N” refers to the number of children in the sample at each interval.

The Range reports the lowest score recorded to the highest score.

The Standard Deviation (SD) is a measure of variability in the scores. (These SD’s are very high, because of the skewed distribution of scores on the ASQ:SE).

The Median is the score where an equal number of children fell above this score as fell below this score.

Because the scores on this questionnaire were unequally distributed, the median provides a more helpful comparison than the mean. However, if programs want to adjust cutoff scores according to their resources and/or populations they are screening, they can use the standard deviations, means, and medians to assist in that process.
