Question

50% of the data values are within ____ points of the median.

Answer 1

hmm, the ends of the box tell us the quartiles

Answer 2

2 quaters = 50% right?

Answer 3

yes,

Answer 4

the box contains what is known as the interquartile range (IQR) which contains 50% of the data; but im not sure how to format that to the question itslef

Answer 5

Would it be 50% of 23 ?

Answer 6

no; lets see if the median is the midpoint between the boxend (not the arms)

so; is (14+32)/2 = 23 ???

Answer 7

if so; then the answer would be how far apart 23 is from 14, or 32 ....

Answer 8

9

Answer 9

i like 9

Answer 10

can u help me on another problem too ?

Answer 11

dunno, i only have a limited amount of smarts that i can conjure up in a day .... do i have it in me?

Answer 12

lol i believe you do.

Answer 13

lets give it a shot :)

Answer 14

The range of the data set is

Answer 15

range is the distance from the tips of the outstreched arms, or in mathing terms

high - low = range

Answer 16

10-34? so it would be 24

Answer 17

24 is correct

Answer 18

:))

Answer 19

What about stem & left plots..... finding medians ?

Answer 20

stem and leafs is just a very basic format to organize the data; the median is still the number in the center of it all

Answer 21

So in this one if would be 54 ?

Answer 22

hmm, well it is in the 5s

you can either add how many data points there are and divide by 2

or start stripping off values from each end till you reach the middle.

if i did it right, i think its 57 if you wanna dbl chk me

Answer 23

5 | 6 7 7

is what i thik im left with

and the middle of that is 57

Answer 24

Now i have a question , how would you get mean out of all that would it be the same ?

Answer 25

the mean of ALL that is just alot of adding up numbers; then divide by how many numbers there are

Answer 26

we can work it like this tho:

take a row:

3 : 0 1 2 3 4 add up the righties = 10

since there are 5 number to the right; multiply that by the lefty; 5*3 = 15

but, since the lefty is a ten digit; its actually 5*30 ... 150

so add those togeher and we get 160 for the first row .....


not fun, but doable

Answer 27

im confused ?

Answer 28

its just adding up all the data points;

the first row has data points:

30
31
32
33
34
-----
160

add up the rest of the rows

add them all together to get a grand total

and divide by how many numbers there are to begin with

Answer 29

1736 i got all together now divide them by how many number there are ?

Answer 30

which i got 56

Answer 31

ill trust you on that 1736 ..

but yes, divide that by how many numbers there are .... which i believe there are 31 of them

Answer 32

google says 56 is good :)

Answer 33

but on the answers there is no 56 its only 57 & 54

Answer 34

double check that 1736 value

Answer 35

i got the same thing again .

Answer 36

160
208
379
529
670
----
1946

but i did it in my head so its prolly bad

1946/31 gets me to 62.7 hmmm

prolly bad head math

Answer 37

hmm , well we were right because i was looking at the wrong one. :D . now i have another question is that okay ?

Answer 38

go ahead and post a new one to the left; i have to get back to my paying dayjob :)
