19,25,23,20,9,20,15,10,5,16,5,16,25,20,24,12,13,14,13,14
find mean
median
range
mode​

Answer 1

Step-by-step explanation:

mean=sum of all observations/no.of all observations

=19+25+23+20+9+20+15+10+5+16+5+16+25+20+24+12+13+14+13+14/20

=318/20

=15.9

Therefore mean is 15.9

median=16,5

=16+5/2

=21/2

=10.5

Therefore median is 10.5

mode is the most frequently occurring value in the observation

Therefore mode is 20
