Question

Quizplus · Accepted Answer

The mean is calculated by summing up all the scores and dividing by the total number of scores. It is appropriate to use for interval or ratio scales since those scales have equal distances between scores, making it meaningful to calculate the average. The median and mode may be used for other types of scales, such as ordinal or nominal, where the distances between scores are not equidistant. However, they may not provide as accurate a representation of central tendency as the mean would for interval or ratio data. The option D, "meridian," is not a valid statistical concept to measure central tendency.
