Question

multiple choice question \
ewline which of the following is not a measure of position? \
ewline \bigcirc 90th percentile \
ewline \bigcirc first quartile \
ewline \bigcirc ninth decile \
ewline \bigcirc standard deviation

Explanation:

Measures of position (like percentiles, deciles, quartiles) show where a data point stands relative to others. The 90th percentile, ninth decile (which is the 90th percentile, as deciles divide data into 10 parts), and first quartile (25th percentile, dividing data into 4 parts) are all measures of position. Standard deviation, however, measures the spread (variability) of data around the mean, not position.

Answer:

O standard deviation
