Glossary I

Intersexual person refers to a person who has genitals suggestive of both sexes.

Interstitial cells are cells responsible for the production of testosterone ;. Interstitial cells is also referred to as Leydig cells.

Intersubjectivity refers to a scientific principle which requires that independent observers see the same thing under the same circumstances for observations to be regarded as valid.

Interval measure is defined as a level of measurement describing a variable whose attributes are rankordered and have equal distances between adjacent attributes. The Fahrenheit temperature scale is an example of this, because the distance between 17 and 18 is the same as that between 89 and 90. Please see nominal measure, ordinal measure, and ratio measure.

Interval method is a term in behavioral observation, a technique for converting observations into numerical scores that involves dividing the observation period into a series of intervals and then recording whether or not a specific behavior occurs during each interval.

Interval of uncertainty refers to the difference between the higher and lower thresholds in a calculation of the difference threshold
Interval recording means recording a response if the behavior occurs in one of a series of continuous intervals. Interval recording refers to the measurement of whether or not a behavior occurs within a series of continuous intervals.

Interval scale refers to a measurement scale that possess the properties of difference, magnitude, and equal intervals. Interval scale, moreover, is defined as a scale of measurement in which the categories are organized sequentially and all categories are the same size. The zero point of an interval scale is arbitrary; a scale that one can use to rank order objects and on which the units reflect equivalent magnitudes of the property being measured.
