Question

@amistre64 can you help me?

Answer 1

The table shows data from a survey about the number of times families travel by car or taxi during an average week. The families are either from a rural town (population under 5,000) or a large city (population over 1 million):

Rural Town City
0 2
1 5
2 6
8 7
9 9
15 14
20 15
25 20
35 25
36 25
40 30

Which of the choices below best describes how to measure the center of this data?
Both centers are best described with the mean.
Both centers are best described with the median.
The country data center is best described by the mean. The city data center is best described by the median.
The country data center is best described by the median. The city data center is best described by the mean.

Answer 2

@slinley

Answer 3

what affects mean and median?

Answer 4

umm...mode

Answer 5

now youre just making stuff up lol

mode is another measure of centrality so no.

outliers ... determine the mean and median for each set, see how off they are from each other.

Answer 6

40 and 30

Answer 7

they are outliers

Answer 8

they are ends, but they seem to be pretty close to their relevant parts

36 to 40 is not as bad as 25 to 35 so its not unreasonable to me as far as the range goes

same for the other side

Answer 9

ohh okay

Answer 10

0,1,2,8,9,15,20,25,35,36,40

2,5,6,7,9,14,15,20,25,25,30

do you have a ti83 maybe? or do you have to work it all by hand?

Answer 11

ti83?

Answer 12

ill take it thats a no, its a texas instruments calcuator with stats functionality on it

Answer 13

oh no I don't

Answer 14

the wolf gives:
------------------------

0,1,2,8,9,15,20,25,35,36,40

mean: 17.36, median: 13
-------------------------

2,5,6,7,9,14,15,20,25,25,30

mean: 14.36, median: 14

Answer 15

so it would be D

Answer 16

first one is median of 15, not 13 ... my fingers hate me

yeah, D seems to be the most reasonable choice.
