The median is the appropriate measure of central tendency when
a. the scale of measurement is nominal.
b. the scores are ordinal, or when the distribution is skewed and the scores are interval or ratio.
c. the scale of measurement is ratio.
d. the distribution is symmetrical, and the scale of measurement is interval or ratio.
Question 2
The mean is used most often in behavioral research because researchers tend to
a. measure variables that have interval or ratio scores, and the scores form approximately normal distributions.
b. conduct research in which the mathematical center of a distribution is required.
c. conduct research in which only the most frequently occurring score is needed.
d. measure variables that have interval or ratio scores, and the scores usually do not form a normal distribution.
