Some scales are given as a ratio, variously written as either a ratio (i.e., 1:300) or a fraction (i.e., 1/300). The number on the right of the pair indicates how many units (inches or centimeters) on the original are equivalent to one unit on the replica. For example, with a 1:300 scale miniature, if the miniature is 1" long, then the original was 300" in length. In spoken English, you would say 1/300 as "one [pause] three hundred scale."
A measuring system having the property that ratios of the numbers assigned accurately reflect ratios of the magnitudes of the objects being measured. This means that a behavior assigned a number of, say, 10, must have twice the magnitude of a behavior assigned a number of 5. Effectively, this requires that there be a true zero, a score that means the behavior is absent. Ratio scales in psychology are almost always physical scales employed to capture behavior, such as the use of response latency to measure task difficulty. Typical “psychological” dimensions, e.g., intelligence or attitude, do not have a “zero” point.
a scale of measurement that indicates the ratio of scores to one another. (641)
A scale with an absolute zero point and equal space between each point; for example, weight or height is measured on a ratio scale.
The highest scale of measurement in which the spacing between values is known and there is a known zero point.
A measurement scale in which numbers indicate levels or degrees of a characteristic in relation to an exact zero (0) point. The distance between each level is equal and each level can be compared to an exact zero (0) point to provide meaningful information. Weight and number of clients receiving services are examples of characteristics measured on a ratio scale.
Data that have a true zero point that represents total absence of the variable.
an interval scale having a unique natural origin which may be assigned arbitrarily
a rule for taking observations and measurements that orders the objects on a common property, provides distances between two objects with respect to their common property, and has a true zero point or origin
The ratio scale has equal units of measurement and has a true zero point. Time, height, and weight are examples of measurements that utilize the ratio scale. Most educational and psychological variables cannot be measured on the ratio scale.
(n) A data scale that has a natural zero point but is insensitive to the units used. Ratio values are often generated by dividing two values that have either similar or dissimilar units.
A ratio scale is an interval scale which has a true zero, i.e., matching the zero value of the measured attribute.
An interval scale in which there is a true zero point, thus allowing statements about proportions (e.g., this sound is twice as loud as the other). See also categorical scale, interval scale, nominal scale, ordinal scale.
A measurement scale in which there are equal intervals between the ranked values and a theoretically meaningful zero. Any mathematical procedure can be used on date measured on aratio scale 22
A scale of measurement that consists of measurements that have a clear (absolute) zero or minimum point and where the intervals are of equal measure. For example, length is a ratio scale because it has a minimum value of zero and the difference between say, 10 metres and 12 metres is the same as the difference between 1045 metres and 1047 metres.
