This will increase your sample from one hundred results to one thousand results. Your combined results will reveal just how common those unexpectedly long clusters really are. Transcribe your results from Tables 2 and 3 into the column labelled 'My Results' in Table 4 below. Share your results with nine other students. Write each person’s name at the top of the remaining columns in Table 4. Then copy their totals from Table 2 into the first two rows, and their results from Table 3 in the rows labelled l to 10. Add all the numbers in the Total Heads row and write the answer in your science journal. To calculate the average number of heads observed in all 1000 results, simply divide this number by 10. Record the result in the average column. Repeat for the Total Heads row. Next, calculate the average frequency of each cluster size observed in your set of data. Again, simply add all ten numbers in each row and divide the total by 10. Write these results in the Average column.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
