At the district competition for 5th grade jump-roper of the year, the following number of jumps without stopping were recorded per student: 203,245,237,233,90,100,100,277,265,264,265,285,288,291,291,290,300,224,200,257,290,279,266,288 What is the mean number of jumps, rounded to the nearest hundredth? What is the median number of jumps?
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
