Question

multiple choice question
each of the following is a measure of position in a set of data except:

the quartiles
the standard deviation
the median
the deciles

Explanation:

Measures of position (like quartiles, median, deciles) show where a data point stands relative to others. The standard deviation measures the spread (variability) of data, not position. Quartiles divide data into quarters, median is the middle value, deciles into tenths—all position - related. So the standard deviation is not a measure of position.

Answer:

the standard deviation
