Question

Sixty students were given a history exam. Their scores are shown below, sorted from smallest to largest. 13 30 35 35 35 38 38 38 38 39 40 41 42 45 47 51 53 65 66 72 74 74 75 75 75 75 76 76 76 76 77 77 78 78 78 78 78 78 79 79 79 80 80 80 80 80 81 81 81 81 81 82 82 82 85 85 86 86 88 94 1) Compute the 5-number summary for this data: 2) Create a histogram of the data. You can create it using software on your computer, using online software, or you can draw it by hand and scan it or take a picture of it. If you can't figure out how to include your histogram in the entry area below, you are welcome to email it to me instead. (Here's a video that shows how to upload images or files into the text editor. The video is for forums, but it works the same way in assessments.) 3) Finally, write a couple sentences describing what conclusions you can draw about performance on the exam from the 5-number summary and the histogram.

Answer 1

By using Excel's we have Five number summary :

Comment: From above 5 plot summary data and Histogram we can say that data is negatively skewed.It means that it has a large number of occurrences in the upper value and few in the lower value . Here median is GREATER than mean. So from histogram we can say that maximum number of students did score well in History.
