Find the Mean, Median, Mode :

3.. Airline Passengers The number of passengers (in thousands) for the leading U.S. passenger airlines in 2004 is indicated below. Use the data to construct a grouped frequency distribution and a cumulative frequency distribution with a reasonable number of classes, and comment on the shape of the distribution.

91,570 86,755 81,066 70,786 55,373 42,400

40,551 21,119 16,280 14,869 13,659 13,417

13,170 12,632 11,731 10,420 10,024 9,122

7,041 6,954 6,406 6,362 5,930 5,585 5,427

Solution

THE MEAN = SUM OF ALL/ TOTAL NUMBER

SUM = 658649

TOTAL NUM = 25

MEAN = 26345.96

MEDIAN = THE NUMBER IN BETWEEN THE WHOLE DATA = 13170

MODE = NUMBER WITH HIGHEST FREQUENCY = NO NUMBER IS THERE
