Fig. 2

Box and whisker diagram of baseline domain performance scores of 1384 public health facilities in Uganda, 2010–2013. The figure displays the distribution of scores in the five domains. Shown are the minimum scores excluding outliers (first whisker - 25^th percentile -1.5*interquartile range [IQR]) and maximum score excluding outliers (last whisker –75^th percentile +1.5*IQR); the first quartile (lower part of the box), the median (line in box), and the third quartile (upper part of the box) and dots show the outlying scores. The spaces between the different parts of the box indicate the degree of dispersion (spread) and direction of skewness in the data for each of the five domains (on a scale of 0–5)
