This course is about the investigation of a disease cluster, it has many samples to study so you can apply this knowledge to your problem. I'm glad to register for this course.
Disease Clusters taught me quite a bit of new information in regard to conducting a disease cluster investigation. I have deducted two stars from my overall rating of the class. The first star was deducted because there was an inordinate amount of repetition. The second star was deducted because there is a student-graded assignment. Students have not been trained to provide fair and through feedback on assignments. Indeed, many are trolls while others don't even understand what they are reading. On this assignment, my paper was marked as having insufficient words by one student grader while the other student grader marked it as having sufficient word length. I just went through and counted the words. I did indeed have sufficient words, just as I thought originally. As a compromise, Coursera gave me half-credit for word count. Coursera needs to base grades on tests/quizzes, unless a teacher is grading assignments.
