We measured five variables: (1) object roll, (2) object lift onset, (3) time to peak object roll, (4) object vertical velocity, and (5) object lift duration.
We measured five variables: gill height and gill depth (side view), gill width (top view), distance between the three gill rachises (front view) and the length of the second gill rachis (top and front views) (illustrated in Figure. 4).
We measured eight variables from each clip using SoundEdit16: chirp duration, chirp period, pulses per chirp, pulse duration, pulse period, chirp peak frequency, pulse peak frequency, and number of harmonics per chirp.
AgNO3-based colorimetric methods can potentially measure two variables, chloride ion penetration depth and chloride concentration at the color change boundary.
S tage of life has been constructed by measuring two variables.
Moreover, our study only uses Medicare Part B claims to measure two variables, continuity of care and primary care physician visits between the first and last functional assessments.
The index measures ten variables, such as the ability to do business, property rights, corruption and labour freedom.
The McGill Mineral Processing group has developed instruments and procedures to measure three variables in industrial cells: superficial gas velocity, gas-holdup and bubble size distribution.
We measured two morphometrical variables – acinar and ductal wall thicknesses.
For this measure two variables were constructed, 'discrepant 1', excluded any missing values for the two questions, and 'discrepant 2' labelled those with missing values for both questions as discrepant.
