that is 6 (that equal 4 or 8) out of 25
so your ratio would be 6:19
Answer:
a) 19 students
b) the mean 3 9/19
the median 3
the mode 3
c) the range 6
Step-by-step explanation:
The data set shows that
0 points gets 1 student,
1 point gets 1 student,
2 points get 2 students,
3 points get 6 students,
4 points get 4 students,
5 points get 3 students and
6 points get 2 students.
a) There are 1+1+2+6+4+3+2=19 students.
b) The mean is
![\dfrac{1\cdot 0+1\cdot 1+2\cdot 2+6\cdot 3+4\cdot 4+3\cdot 5+2\cdot 6}{19}=\dfrac{66}{19}=3\dfrac{9}{19}.](https://tex.z-dn.net/?f=%5Cdfrac%7B1%5Ccdot%200%2B1%5Ccdot%201%2B2%5Ccdot%202%2B6%5Ccdot%203%2B4%5Ccdot%204%2B3%5Ccdot%205%2B2%5Ccdot%206%7D%7B19%7D%3D%5Cdfrac%7B66%7D%7B19%7D%3D3%5Cdfrac%7B9%7D%7B19%7D.)
The average score is 3 9/19 points.
The median is 10th term in the data set - 3 points (means the middle score in the data set)
The mode is 3 points (means most happened score)
c) The range of the data is 6-0=6 points.
