What is the median number of jumps?

Respuesta :

The mean is 242.83 and the median is 264.5

Answer with Step-by-step explanation:

Mean=sum of all observations/total number of observations

Median is the middle term of the data set after arranging the data in ascending order

Here,data set is:

203,245,237,233,90,100,100,277,265,264,265,285,288,291,291,290,300,224,200,257,290,279,266,288

Mean=5828/24

Mean =242.833

Now, we arrange the data in ascending order:

90,100,100,200,203,224,233,237,245,257,264,265,265,266,277,279,285,288,288,290,290,291,291,300

Median lies between 12th and 13th term

i.e. 265

Median=265
