Question

Find the range, mean, median, and mode of the data given below.
19.25, 16, 24, 20, 16, 19, 17, 16, 12, 16, 28, 11, 9, 16, 25, 19, 16,
​

Answer 1

range = 28 - 9

= 19

mean = sum of all observation / no. of observations

= 19.25+16+24+20+16+19+17+16+12+16+28+11+9+16+25+19+16 / 17

= 299.25 / 17

= 17.602941

median = 12

mode. = $16$
