Quantile Plots
How to do it

The upper and lower bars represent the 90th and 10th percentiles respectively. The
red bar in the middle of each box represents the median. The box extends from the
25th to the 75th percentile. The blue dot is the mean with lines extending one standard
error of the mean in each direction. The dotted line is the mean averaging across
all groups.

Positive values show pairs of means that are significantly different.
The table above shows the difference between absolute value of the difference between
means and the size of the difference needed to be significant (Least Significant
Difference or LSD). A positive value indicates that the difference between means
is larger than the LSD and therefore the comparison is significant. Only the difference
between the false smile and neutral expression is significant.
