Statistics deals with collecting and analyzing data, this broad concept can be applied to almost everything. When dealing with electricity it is very important to know how it is being used. For example, Con Edison receives massive amounts of data on how much power is being used by people. Based on these statistics it provides consumers feedback on how they can lower their energy bills and what home installations they can make to best suit their energy needs. On a larger scale, by looking at past trends utility companies such as Con-Edison can figure out times of peak demand and shortage. For example if on a rainy day in late may, it is found that there is a surplus of power. Based on statistical analysis from previous year’s data, Con Edison can figure out when will be the closest day of peak demand. If the closest day, is predicted to be 2 days from the rainy day then arrangements can be made to store the excess power temporarily. However if the statistics say that the next peak demand day will be 2 weeks from the rainy day then Con Edison will know that it is a lost cause because the power cannot be stored for such a long period of time. And it is best to use the power for internal operations rather than sell it to customers.
Taking statistics this semester was a good experience. I personally think that I learned in depth statistics, and challenging concepts. This course was challenging but in a good way. I have never taken a taken a full statistics course, besides what was touched up on in trig in high school which was about 5 years ago. Lectures were interesting and the pace of the class was nice. Like I mentioned in the post above statistics is used in many fields of engineering, one being power as mentioned in the original post. Another example would be in manufacturing, if an electronics company receives a shipment of motherboards, they can test the null hypothesis that the shipment is full of defective parts by testing to see the magnitude of the p value. Statistics is widely used in manufacturing and design. Another example would be to find the purity in refined silicon material, finding the purity of 1 cm^2 and then extrapolating the entire area.
