The data I chose was number of pigs in a litter. According to current farm data, the average litter of pigs born alive is eleven (Factors Affecting Litter Size - Pig Articles from The Pig Site, 2014). According to the data there was a total of 4,461 pigs born in 378 litters for an average (mean) of 11.8 pigs per litter (Hand, D. J., Daly, F., Lunn, A. D., McConway, K. J., & Ostrowski, E., n.d.). After putting the data in order from least to greatest I knew there would be two center numbers (because there was an even amount of data) so I had to find the average of the 189 th and 190 th pieces of data. Since both were 12, the median is 12. The number of pigs in a litter that occurred most often was 11. There were 55 litters of 11 pigs (Hand, D. J., Daly, F., Lunn, A. D., McConway, K. J., & Ostrowski, E., n.d.). The standard deviation is 3.35 which means that any litter greater than ¿ 8.45 and less than 15.15 are within one standard deviation of the mean. The mean absolute deviation is 2.59. The minimum value is 1, the 1 st quartile is 10, the median is 12, the 3 rd quartile is 14, and the maximum value is 21.

    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.
