The theoretical description of light rays transport inside the tubular light guide and their distribution on the output from the light guide at the level of the ceiling is presented.
Categorical variables are summarized in terms of frequencies and percentages, and for each continuous variable, the mean, standard deviation, median, range, percent at floor, and percent and ceiling are presented.
I heard from her what I hoped I'd hear - that no "glass ceilings" are present in our firm and that we are "truly ahead of the curve in eliminating gender pay gaps".
A floor effect was not observed but a ceiling effect was present for all scorers with notable values for the PWB (26.87%), SWB (16.42%), EWB (16.42%) subscales and the EQ-5D utility (47.76%) [ 26].
A ceiling effect was present for both versions of the survey, as commonly seen in patient satisfaction surveys [ 34– 34].
Perhaps a ceiling effect was present, limiting the chance of improving perception of touch and/or vibration sense in these patients by intervention using temporary anesthesia.
The floor effect was not relevant, but quite a high ceiling effect was present in almost all domains, especially for 'Self-care' (53.6%).
A visual inspection of the frequency distributions confirms that a ceiling effect is present in approximately 60% of the items and a floor in 10% of them.
A ceiling effect is present when at least 15% of respondents scored the highest possible score on the scale.
If 15% of the candidates obtained the minimum or maximum sub-scale score a respectively floor or ceiling effect was present [ 27].
Earlier validation studies of the AQLQ included asthma patients from clinical settings, where AQLQ scores were substantially lower and where no ceiling effect was present [ 10, 23- 26].
