In a race, Sam came in first and Fred second. Determining the difference in time to complete the race between Sam and Fred involves an ordinal scale TrueDetermining the number of students in each section of introductory psychology involves the use of a ratio scale. TrueNominal scales can be used either qualitatively or quantitatively.
In rounding, if the remainder beyond the last digit is greater than 1/2, add one to the last digit. If the remainder is less than 1/2, leave the last digit as it is. TrueA discrete variable requires nominal or interval scaling. TrueOne generally has to specify the real limits for discrete variables since they cannot be measured accurately. FalseMeasurement is always approximate with a continuous variable.
Most scales used for measuring psychological variables are eitherratio or interval. FalseAll scales possess magnitude, equal intervals between adjacent units, and an absolute zero point. FalseThe average number of children in a classroom is an example of adiscrete variable. FalseWhen rounding, if the decimal remainder is equal to and the last digit of the answer is even, add 1 to the last digit of the answer. FalseClassifying students into whether they are good, fair, or poor speakers is an example of ordinal scaling. TrueWhen a weight is measured to 1/1000th of a gram, that measure is absolutely accurate. False
