Assignment #1


Reflection Number 1

With my results I found that Eau Claire North should not be worried about losing their jobs. They absolutely should not be worried about not having the highest test scores. Eau Claire North had an average test score higher than Eau Claire Memorial. From what the data is showing us, we see that Eau Claire North had a higher mean, median, mode, a smaller range and a smaller standard deviation. That means that there average was higher and that there is less variation in there test scores in comparison to Eau Claire Memorial. Eau Claire Memorial did have a slightly higher max score than Eau Claire North, but in contrast Eau Claire North's low score was higher than Memorials.

Reflection Number 2




           

The information that was collected for this report was number of organic goat farms per county, and the number of goats that were in each county. Also I looked into the differences from the mean, the percent each county contributed to the total of goats and farms. The map to the left shows the number of organic farms per county. Vernon count has the most farms. It is easy to see the distinct pattern, the southwest corner of the state has consistently more than anywhere else just as northern Wisconsin has a very minimal amount of organic farms. This is because of the type of land that is in these areas. Northern Wisconsin is not typically known for agriculture, there are big stands of timber and not much prairie land.
            The second map I have to display shows the percent of organic farms by county from the total. Vernon County is again the only county in the top percentage bracket. With the Jenks method of classification, these maps look nearly identical. The map below illustrates the difference between the mean and the actual number of organic farms.

            Illustrated below is a map that shows the number of goats as a percent of the total goat population per county. This map gives us a better idea of where most of the goats are located.

            In step one of part two of the assignment, I calculated a new column called the Difference from the average. This gave us an idea of what counties were close to the mean and what counties either had more or less than the data would have originally suggested. I would say the patterns when looking at these maps simply shows us that the southern half of the state holds the best chance for organic and goat farming. I would place a farm somewhere in the central farmland area. There is good woods cover, plenty of agriculture and you wouldn’t be competing with the goat farmers in Vernon County. I think the map that showed the percentage of farms from the total showed my angle the best. It showed that there are farms in the central area, but the most are in the southwestern corner. I think that there is somewhat of a lack of data here. I am not sure if they are only counting goats that are on organic farms or all goats in general because there is a goat farm near my house that has over fifty goats, but it says there isn’t even that many goats in that county. So I would like to read about the methods for collecting this data. The distribution of the organic farms is not very evenly distributed, there is one county with 229 farms and another with 0. Then with a standard deviation of 28.19 and a mean of 16, that county with 229 is an outlier. The number of goats is a lot better as far as kurtosis goes. The distribution is more even, with a mean of 33.5, and a standard deviation of 23.20, majority of the counties fall within a reasonable variance from the mean. Then looking at kurtosis, goats have a kurtosis of .53 compared to that of the organic farms which was 46.5. The organic kurtosis is almost 100 times that of the goats. So this shows that the goats have a very normal distribution, in contrast the organic farms have a leptokurtic relationship because most of the number of farms per county are around the mean, there is a long tail going towards the positive end.
