This is for Connections Academy Lesson 4 Stem and Leaf Plots
1. A - 37, 38, 39 etc
2. C 54; 73
3. D the height of NBA basketball players
4. C - its a graph
5. D 35
6 D - Mean, the outliers are limited
7 C 6 years
8 is a short answer where you just need to find the means and modes of the plot
thanks moon😊
1. A
2. C
3. D
4. C
5. D
6. D
7.
Doctor 1 : Mean = 12 / Median = 12
Doctor 2 : Mean = 16 / Median = 18.5
Data from the stem and leaf plot :
Doctor 1: Age of the patients: 1, 1, 2, 3, 7, 9, 15, 17, 18, 20, 22, 29
Doctor 2 : Age of the patients: 2, 2, 3, 9, 13, 17, 20, 20, 22, 23, 26, 35
Both doctor 1 and 2 had 12 patients that day.

Answers I got from here!
1. A
2. C
3. D
4. C
5. D
6. D
7. C
8. Doctor 1 : Mean = 12 / Median = 12
Doctor 2 : Mean = 16 / Median = 18.5
I can compare the two doctors because they both had the same amount of patients in that day. Both doctors had 12 patients.
you dont find the mode, you have to find the median. but yes moon is correct !
whats the #8 awnser!!! (confusing)
@vegandragon is wrong you will only get 4/7
I need the answer to #8 its very confusing
@XD is right
i needdd the esssay
1. A
2. C
3. D
4. C
5. D
6. D
7. C
8. (I DIDNT UNDERSTAND HOW YOU ARE SUPPOSE TO COMPARE THEM)
Doctor 1 - mean: 12 median: 12
Doctor 2 - mean: 14 median: 18.5
What grade is this for?
Hey Thank you for the help
heres the anwser for 8 uwo nya~~
1 2 3 4 5 7 7 9
There practically just putting the numbers in order then you put the tens in the stem and the ones in the leafs area
64,69,88,88,91,91,93,94,95,97,97,99
Jut put a bar between those numbers
THIS IS FOR THE 8TH GRADE LEVEL!!!
1. A: 37, 38, 39, 41, 43, 46, 52, 54
2. C: 54; 73
3. D: the hight of NBA basketball players, in meters.
4. C: the graph where the fourth bar is the shortest.
5. D: 35
6. D: Mean; the outliners are limited
7. C: 6 Years
8. Copy this into the field
Doctor 1: Mean = 12 / Median = 12
Doctor 2: Mean = 16 / Median = 18.5
I can compare the two doctors because they both had the same amount of patients that day. Both doctors had 12 patients.
Good Luck! :)

8. The back-to-back stem-and-leaf plot below shows the age of patients seen by two doctors in a family clinic one day. Compare the ages of the patients of Doctor 1 and Doctor 2 using the mean and the median of each data set.
Age of Doctor's Patients
Doctor 1 Doctor 2
| 3 | 5
9 2 0 | 2 | 0 0 2 3 6
8 7 5 | 1 | 3 7
9 7 3 2 1 1 | 0 | 2 2 3 9
Key: means 29 <-- 9|2|3 --> means 23
For this question, I just put the mean and median for each doctor.
3 | 7 8 9 ---> 37, 38 , 39
4 | 1 3 7 ---> 41 , 43 , 47
5 | 2 4 ---> 52 , 54
and a. is:
a. 37, 38, 39, 41, 43, 47, 52, 54
so I do not think c is right.
I am not educated enough in this to look at the rest.
