Lab 10



While Shannon's method uses probability, the Hartley method lacks probability. Hartley uses the log base 2 for all numbers. Because of this, Shannon's is more useful because the amount of uncertainty within a set of alternatives is calculated by how much information is needed.

Lab 9

Within this lab, I basically refreshed my memory of excel when I was in the K-201 course. In this lab however, we learned how to use formulas such as SUM and COUNT which made solving arithmetic for multiple columns much easier. Also, we learned how to create histograms which was extremely efficient but at the same time very easy to do. One of my favorite features of Excel is the drag down function that cuts down on time and work. It is extremely handy when working with several columns and rows. In my opinion, Excel is probably one of the most popular and most useful software that companies use. If a company needs to make lists of eligibility for certain benefits for employees, Excel is easily capable of doing that. There will be a great chance that when I am hired for a company, software like or Excel will be used. I enjoy using Excel and hope to learn more about it within the near future.
