We are interested in studying the performance of college students on statistics exams. in any
given semester, there are hundreds of students taking statistics in the department of psychology,
mathematics, business, or other related departments that offer a course on statistics. we
randomly select 20 students from the roster of all students enrolled in statistics for the spring
semester and administer questionnaires throughout the semester, as well as collect their
assignment and exam grades. in our first analysis, we are interested in examining the grades
from all the students on exam 1 in their course. all exams were out of 100 points. this data is
below:
90 75 67 56 89 88 34 67 95 81
76 69 72 73 79 83 42 53 78 80
1. draw a frequency distribution of the data. what can you determine from this
distribution?
