Ms.C collected the following scores for 28 students in her class. Use the graph to answer the following:
What is the median and what does it mean in the terms of this context?
What is the median and what does it mean in the terms of this context?
Median: 68
It means that the majority/average of her students are closer to passing then failing.
200
For the data set answer the following:
Find the median:
40,20,10,60,30,50
Median: 35
200
Find the following:

Ms.C collected the following scores for 28 students in her class. Use the graph to answer the following:
What is the interquartile range of the data? What does it mean in terms of the situation?
What is the interquartile range of the data? What does it mean in terms of the situation?
Interquartile: Upper - Lower= 87-52= 35
It means the difference in grades from the highest peak to the lowest.

For the data set answer the following:
Find the Lower & Upper Quartile :
40,20,10,60,30,50
Lower: 20
Upper: 50
300
Find the following:
Min: Lower quartile: Median:
Upper Quartile: Max:
Symmetry: Interquartile:
Min: 30 Lower quartile: 55 Median: 78
Upper Quartile: 100 Max: 125
Symmetry: No, skewed right Interquartile: 45

Ms.C collected the following scores for 28 students in her class. Use the graph to answer the following:
Does the data appear to be symmetrical? Explain why or why not?
Does the data appear to be symmetrical? Explain why or why not?
Yes, it is symmetrical because median is in the middle.
400
For the data set answer the following:
Find the mean & Graph this data set:
40,20,10,60,30,50
Mean: 35
Graph is on One note

Ms.C collected the following scores for 28 students in her class. Use the graph to answer the following:
About what percentage of students grades are 70 & higher? How many students would this be approximately? Show your work.
50% of students have a 70 or higher. Based on the 50 % there are 14 students who are in that range.
28 x .50 = 14 students
500
For the data set answer the following:

What conclusions can you draw from comparing the data from the box and whisker plots?
The majority of students are passing but a few are border line need to improve.
