101 135 122 43 110

62 31 80 67 126



Calculate the mean and median data values for the student athletes sample.
Calculate the mean and median data values for the not student athletes sample.
When comparing the two samples, what conclusions can you draw about which group spends more time studying each weeknight?

Answer 1

So find the mean, and median values for each set : )
Remember.. the means is add them all up and divide by the number in the set.
While the median is arrange each set from smallest to biggest and find the middle piece of data : )

Answer 2

STUDENT ATHLETES:

Because I got STUDENT ATHLETES MEAN is 86 and the MEDIAN 93. The NON STUDENT ATHLETES MEDIAN is 90.5 and the MEAN 87.7

Answer 6

he is correct

Answer 7

not sure but i assume

Answer 8

The answer is a. mean=86 and median=93

b. mean=87.7 and median=90.5

c. The mean for non-athletes is 1.7 minutes greater than for the athletes and the median for athletes is 2.5 minutes greater than for the non-athletes. So, it is too close to draw a conclusion at this point.

REWORD IT!!
