Answer:
Hey there!
We have:
4 students with 5 marks.
8 students with 6 marks.
10 students with 7 marks.
7 students with 8 marks.
13 students with 9 marks.
3 students with 10 marks.
Thus, the mean is: , or around 7.58 marks.
The median is the middle number and since we have 45 people, the middle number would be the 23rd. 4+8+10+1=23, Thus, 8 marks i s the median.
The mode is the most common score, which is 9.
The range is the range of all the values, which is from 5-10. Thus, giving us a range of 10-5, or 5.
Hope this helps :)
