Caption: Figure 2--Comparison of the median values [+ or -] semi-interquartile range
of the central comeal touch threshold (CTT) in the right eye (OD) for different breeds.
Our study population was made up of 16 laryngectomized patients--14 men and 2 women (median age: 62 yr; semi-interquartile range
: 52.5 to 65.5)--who had undergone laryngectomy between 1995 and 2003.
Vital concepts to master here include standard deviation, standard error of the mean, semi-interquartile range
, validity, reliability, correlational studies, experimental studies, stanines, standardized and criterion referenced tests, and pilot studies.
"Q" represents the Quartile Deviation (or semi-interquartile range
Pupils who have taken the test(s) may receive notice of their results in terms of percentiles, standard deviations, and/or semi-interquartile ranges
. Pupils' test results may be compared with other classrooms, schools, and school districts.
