Answer:Solution:
We use the basic formulae of mean, median and mode to solve the problem.
Total number of players = 11
Scores of the players = 6, 15, 120, 50, 100, 80, 10, 15, 8, 10, 15
Arranging the scores into ascending order, we get
6, 8, 10, 15, 15, 15, 50, 80, 100, 120
Mean = Sum of all scores / Total number of players
= 6 + 8 + 10 + 15 + 15 + 15 + 50 + 80 + 100 + 120 / 11
= 429 / 11
= 39
Thus, mean = 39.
Mode is the observation that occurs the highest number of times.
Here, 15 occurs 3 times in the given data.
∴ Mode = 15.
The arranged data is: 6, 8, 10,10, 15, 15, 15, 50, 80, 100, 120
Median is the middlemost observation of the given data
There are 11 observations here. Thus the middle value is the 6th observation.
∴Median = 15 (6th observation)
Thus, Mean = 39 , Mode= 15 and median = 15. No, the mean, mode, and median are not the same.

Answer:
Step-by-step explanation:
Given:
Ages of 10 men.
Ages are 32 , 51 , 38, 64, 45, 36, 33, 43, 48, 50.
To Find:
What is the mean age of men ?
Solution: As we know that to find mean of a given data just add all the observations and divide that by number of observations.
★ Mean = Sum of observations/Number of observations ★
Here, in this data .
➟ Sum of all ages of 10 men = 32 + 51 + 38 + 64 + 45 + 36 + 33 + 43 + 48 + 50
➟ Total sum = 440
There are 10 men so number of observations is 10.
Now,
\implies{\rm } Mean = 440/10
\implies{\rm } Mean = 44
Hence, the mean age of men is 44
