Math HELP! Ms.Sue

The stem-and-leaf plot
shows the heights in centimeters of Teddy Bear sunflowers grown in two different types of soil.

Soil A| |Soil B
| 5 |9
5 2 1 1| 6 |39
510| 7 |023678
21| 8 |3
0| 9 |

Key: 9|6 means 69, Key: 5|8 means 58

a) Describe the overlap of the two sets of data.

b) Calculate the mean of each data set.

c) Calculate the mean absolute deviation (MAD) of each data set.

d) Which set is more variable? How do you know?

  5. First you need to be able to interpret the stems and leaf plot (since there are two stems).
    The two bars enclose the 10's digit, and the numbers to the left of the first bar represent the units digit for soil A, and the numbers to the right of the second bar stands for the units digit of soil B.
    Therefore:
    Soil A has data recorded as:
    61,61,62,65,70,71,75,81,82,90
    Soil B has data recorded as:
    59,63,69,70,72,73,76,77,78,83

    a. The overlap is the range of data that is common to both soils, namely between 61 (from soil A) and 83 (from soil B).

    b. The mean is the average, calculated by adding up all data and dividing the sum by the number of values.
    Soil A:
    (61+61+62+65+70+71+75+81+82+90)/10=71.8

    c. the mean absolute deviation (MAD) is also called the mean deviation. This is obtained by adding the difference between each value and the mean, but without regard to the sign. The sum is then divided again by the number of values.
    MAD for soil A
    = ((71.8-61)+(71.8-61)+(71.8-62)+...
    +(71.8-71)+(75-71.8)+(81-71.8)+(82-71.8)+(90-71.8))/10
    =8.16

    d. compare the size of MAD for each soil.
    MAD measures the variability of a dataset.

Okay, I am from Connexus and yes I'm looking on here for answers so you can call it cheating but I'm at the end of my school year and I'm way behind so I said screw it and I just want to get it done, and to whoever harasses people for "cheating" go get a life and stop judging people for what they're doing, we honestly don't care about your opinion

  9. Nice job wasting time to start drama instead of doing your schoolwork and worrying about what other people are doing, you must be autistic. I now know your true colors and how many brain cells you've lost due to that comment you made. Now, I have a life to life and I suggest you grow up from your irrelevant comments.

    Soil A is more variable, because the MAD is higher

  38. wow this is still going on here is the answer to the quistion asked btw subscribe to my youtube
    gamer wolf_izzy

    1. if there were 40 turtles tagged in 2009 16/50=32 percent of the population was taged making the population 40/.32=125
    in 2010 8/30=26.7 percent of the population was tagged so the population is around 150

    2.the mode is 58 because it is the most frequent number the median 86-75=11 because you put the numbers in order rfom least to greatest and grab the two middle numbers then subtract the mean is 468 divided by 6 equils 78 because you have to add all of the numbers in the set then divide by how many numbers there is

    3.Overlap: 22
    Mean:|A: 71.8 |B: 72
    MAD:|A: 8.16 |B: 5.4
    Soil A is more variable, because the MAD is higher

    i dont care if you copy and past just make sure to change some words in it

  43. Annoymous you're maybe the Worst To cause Drama first of all Because You're Comment is stating that she's or he's "Autistic" Which is Very Offensive and Rude. If you wouldn't have Responded To her Or his Comment, I'm pretty Sure a lot Of other's wouldn't have bothered to go On without any Complaint. So technically you started this mayhem you always Do.
