Question

Can someone help me with the stem and leaf plot?

Answer 1

these three

Answer 2

Part A: To calculate the measures of center, we need to find the median and mean for each school.

Bay Side School:
To find the median, we need to first order the data from smallest to largest:
0, 0, 2, 2, 3, 4, 5, 5, 6, 8, 8, 25, 30, 43, 50
The median is the middle value, which is 6.

To find the mean, we need to add up all the values and divide by the total number of values:
(8+6+50+5+8+43+25+30+20+4+2+5+3+2+0)/15 = 14.6

Seaside School:
To find the median, we need to first order the data from smallest to largest:
0, 1, 2, 3, 5, 5, 6, 7, 7, 8, 8, 24
The median is the middle value, which is 6.5.

To find the mean, we need to add up all the values and divide by the total number of values:
(0+1+2+5+6+8+5+5+7+7+8+3+0+6+24)/15 = 6.33

Part B: To calculate the measures of variability, we need to find the range and interquartile range for each school.

Bay Side School:
The range is the difference between the largest and smallest values:
50 - 0 = 50

To find the interquartile range, we need to first find the first and third quartiles. The median splits the data into two halves, and the first quartile (Q1) is the median of the lower half, while the third quartile (Q3) is the median of the upper half.
Q1 = (2 + 3)/2 = 2.5
Q3 = (25 + 30)/2 = 27.5
The interquartile range is the difference between Q3 and Q1:
27.5 - 2.5 = 25

Seaside School:
The range is the difference between the largest and smallest values:
24 - 0 = 24

To find the interquartile range, we need to first find the first and third quartiles.
Q1 = (2 + 5)/2 = 3.5
Q3 = (7 + 8)/2 = 7.5
The interquartile range is the difference between Q3 and Q1:
7.5 - 3.5 = 4

Part C: If you are interested in a smaller class size, Seaside School would be the better choice as it has a smaller range and interquartile range compared to Bay Side School. This suggests that the class sizes are more consistent and less variable at Seaside School.

Answer 3

U think I wouldnt look that up??

Answer 4

That’s nowhere on Brainly, I got it mysefl

Answer 5

Myself

Answer 6

liar

Answer 7

u gotta be smart smart for that

Answer 8

Look at my answer here and see the answer u see on Brainly, you’ll see the difference cause I know what u talkin. Look before assuming I copied an answer

Answer 9

let me check

Answer 10

thats gotta be copied

Answer 11

there are no 50s in the plot

Answer 12

I’m telling you it’s not

Answer 13

where'd you get the number 50 from then

Answer 14

Oh sorry my mistake, I apologize for the mistake. I mistakenly included the value of 50 in the Bay Side School data, which was not in the original stem-and-leaf plot provided in the question. Here is a revised and accurate answer:

Answer 15

Do you still want it or

Answer 16

No

Answer 17

yes

Answer 18

if u did this urself u gotta be smart af

Answer 19

I have my ways, that’s all ima tell u

Answer 20

Part A: To calculate the measures of center, we need to find the median and mean for each school.

Bay Side School:
To find the median, we need to first order the data from smallest to largest:
0, 0, 2, 2, 3, 4, 5, 5, 6, 8, 8, 20, 25, 30, 43
The median is the middle value, which is 6.

To find the mean, we need to add up all the values and divide by the total number of values:
(8+6+5+8+20+4+2+5+3+2+0+5+3+2+0)/15 = 4.6

Seaside School:
To find the median, we need to first order the data from smallest to largest:
0, 1, 2, 3, 5, 5, 6, 7, 7, 8, 8, 24
The median is the middle value, which is 6.5.

To find the mean, we need to add up all the values and divide by the total number of values:
(0+1+2+5+6+8+5+5+7+7+8+3+0+6+24)/15 = 6.33

Part B: To calculate the measures of variability, we need to find the range and interquartile range for each school.

Bay Side School:
The range is the difference between the largest and smallest values:
43 - 0 = 43

To find the interquartile range, we need to first find the first and third quartiles. The median splits the data into two halves, and the first quartile (Q1) is the median of the lower half, while the third quartile (Q3) is the median of the upper half.
Q1 = (2 + 3)/2 = 2.5
Q3 = (20 + 25)/2 = 22.5
The interquartile range is the difference between Q3 and Q1:
22.5 - 2.5 = 20

Seaside School:
The range is the difference between the largest and smallest values:
24 - 0 = 24

To find the interquartile range, we need to first find the first and third quartiles.
Q1 = (2 + 5)/2 = 3.5
Q3 = (7 + 8)/2 = 7.5
The interquartile range is the difference between Q3 and Q1:
7.5 - 3.5 = 4

Part C: If you are interested in smaller class sizes, Seaside School would be the better choice based on the given data. Seaside School has a smaller range and interquartile range compared to Bay Side School, suggesting that the class sizes are more consistent and less variable at Seaside School. However, it is important to note that class size is only one factor to consider when choosing a school, and other factors such as academic programs, extracurricular activities, and location should also be taken into account.
