Determining a person's reaction time (in milliseconds) would involve measurement on a(n) ____ scale of measurement.
goldfiish [28.3K]

Correct Answer: Ratio

Determining a person’s reaction time would involve measurement on a ratio scale that is expressed in milliseconds. It is a point where none of the quality being measured exists and its scale has an absolute zero. In ratio scale, it allows comparisons such as being twice as high or one-half as much. Additionally, in the case of a person’s reaction time, it can be state that a response of 25 milliseconds is twice as fast as a response time of 50 milliseconds.

The Mendelian trait alleles may be dominant or recessive and they will passed down from parent to child. In plants, for example, the color trait of the flower will depend on the type of allele inherited by the offspring. Each parent plant transfers one of the alleles to their offspring and the dominant allele shows itself in the appearance.
