Answer:
The median for Week 2 is more than the median for Week 1.
Step-by-step explanation: Remeber that Range of a set is the difference of the largest number and smallest number.
Median is the middle number of a set. If we have 20 numbers, the middle numbers will be the average of the 10th and 11th number. If we have 21 numbers, it would be the 11th number.
Mean is Σ[tex]\frac{x+x_{2} +x_{3} .....+x_{n} }{n}[/tex] , n is the number of terms in a set. This expression means add up all the terms in the set, and divide by the number of terms in a set.
We have a dot plot . Number of dots represent frequency, and the number is our quanititive data. so our following set for Week 1 is
{62,68,68,68,69,70,70,72,72,72,75,75,76,78,78,80,80,80,89,89}
Let find its Range, Median, and Mean.
Range is 27.
Median is 73.5
Mean is 74.55
For the second data set, the following set is
{62,68,68,68,69,70,70,72,72,72,75,75,76,78,78,80,80,80,85, 86,86,86, 88,88,88,88,89,89,89,89}.
Range is 27
Median is 79
Mean is 78.8
So according to both sets, W1 and W2 have the same range, but W2 have a higher mean and median.
So the answer is The median for Week 2 is more than the median for Week 1.
