Meredith is a very consistent bowler. Her most recent scores are expressed in the following stem-and-leaf plot.

What is the median of her scores?

117
119
121
122

Answer 1

Okay do you know what the greatest value is based on the stem and leaf plot?

Answer 2

9

Answer 3

wait omg I don't know I feel so dumb

Answer 4

do you mean between stems and leaves or just out of the leaves, sorry if I'm very back and forth I'm trying to do a million things at once including this and school

Answer 5

Not quite, lets look at the left side first


Which is the greatest from these?

Answer 6

14

Answer 7

Right
Now lets look at its row

Which of these are the greatest?

Answer 8

4

Answer 9

Yes

So the largest point is 144 (based on the rule given)


Does that make sense? (I can try to explain in a different manner if you wish)

Answer 10

it does actually. so this is for the first question?

Answer 11

Not yet, the range it the maximum- minimum


What is the smallest number here?

Answer 12

smallest of the whole plot?

Answer 13

Yes

Answer 14

Use the same technique we just did to find the largest number

Answer 15

ok so 10

Answer 16

and then 0?

Answer 17

Good :)

10 | 0 would be?

Answer 18

100

Answer 19

Good!

Now subtract 144 and 100

Answer 20

44

Answer 21

Answer to first Q

Answer 22

oh ok that makes sense

Answer 23

Okay mode is the number that appears most often

For this you want to look at the leaves, which number occurs the largest amount of times?

(The number has to be there a lot of times in the row, not all together )

Answer 24

1?

Answer 25

Well that is one of the modes

1 occurs a maximum of 2 times in the last row

Answer 26

wait so there can be multiple modes or no?

Answer 27

There can

Answer 28

so 1 2 and 3 come up multiple times.

Answer 29

or just one and two

Answer 30

Good, that is your answer to the second Q

(You're right, it is 1,2 and 3)

Answer 31

oh ok

Answer 32

so then on the last question.

Answer 33

To find the median start crossing out numbers in pairs, delete the first number on the leaf and then the last one (That is 1)

Keep doing it until you get 1 or 2 numbers left

Answer 34

wait so what do you mean by pairs

Answer 35

So you see when I crossed out 0 and 4 I put a "1" under them?


2 numbers crossed out is a pair

Answer 36

so you cross out randomly or how do you cross then out. I feel so dumb omg, just basically what or is there a way to crossing them out

Answer 37

Go from least to greatest on the top and
Go from greatest from least on the bottom

Answer 38

so then it leaves you with 1 and 7 right?

Answer 39

Yep (If you are ever left with 2 numbers, find the average between them)


What is 11 | 7?
and
What is 12 | 1?

Answer 40

117 and 121

Answer 41

To find the average add them up and then divide by the number of numbers you added

117 and 121 are \(\bf 2\) numbers

So,

\(\large \frac{117+121}{2}=\) answer

Answer 42

119

Answer 43

Yep

Answer 44

Thank you so much!

Answer 45

I have one more question but I will do it in a different one cause this one is big
