Hello SolutionsPro here is Week 5 COMP 102 assignments. Thank you.;Part I Week 5 DB assignment;For this Discussion Board, visit the Excel Web site found here and consider the following;Investigate the various functions that you find on the site.;Look for information about a function that interests you and that you did not already know. You need to find a function that some else has not covered. You may want to explore 1 or 2 functions before you begin your Discussion Board post.;After your research is complete, come back to the Discussion Board and post 1?2 functions that you found interesting.;In your own words, please post a response to the Discussion Board and comment on other postings. You will be graded on the quality of your postings.;Part II Week 5 DB response to classmates;Ashley McCarthy;Functions: Average and Median;Two functions that I did not know about in Excel are the average function and the median function. The average function finds the "arithmetic mean." I did not realize that the average was a little more broader then when I expected. The average "can be numbers or names, arrays, or reference that contain numbers (excel, 2014)." This function is useful for finding monthly averages when budgeting or even keeping stats on football players yardage. The median function is also must like the average function, but this function just takes the middle number of the group of numbers that are listed. When needing to find the median instead of the average, this function can be very useful. Say you had to list a 100 different numbers and you did not want to categorizes or list them numbers least to most, you can list the numbers randomly and the function will find the middle number for you. Its useful and saves time.;Reference;Microsoft. 2014. Excel. Retrieved from http://office.microsoft.com/en-us/excel/;David Hollingsworth CUMIPMT and CUMPRINC (enhanced by ABS, IF, ISNUMBER, and DATE);Excel has so many functions that I?m not sure that any one person has a practical use for all of them. For me, though I use Excel regularly, most of the functions in the engineering and financial sections of the assigned reference have very uses. For someone in those industries, I?m sure they are very valuable functions. As I do manage budgets in excel, I took this opportunity to explore the financial section to see if anything popped out.;A set of functions within the financial section seemed like a great tool for looking at loans and interest. If, say, I wanted to buy a house or get a business loan I would need to be prepared with more exact loan, interest, and payment information than I have time to calculate longhand. In order to show this usage and know that I was operating the functions correctly, I created a test spreadsheet to calculate loans which I have attached to this post.;To make my calculations I used the ?CUMIPMT? function (possibly short for Cumulative Interest Payment) and the ?CUMPRINC? function (possibly short for Cumulative Principal) (Microsoft Corporation, (n.d.). With these functions, Excel can calculate how much a loan payment will be, how much principal is paid from each payment, and how much interest is paid from each payment. It also asks for a payment range so it could return the sum of all payments in that range.;The arguments for both of these functions are the same. (Function arguments are a comma delimited series of the information needed for the function to work.) The arguments are as follows;1. Interest rate.;2. Total number of payments.;3. Total amount of the loan.;4. First period to be counted.;5. Last period to be counted (can be the same as the first if you only want to see one payment).;6. Timing of the payment within the period.;While testing, I came across an interesting note about these functions. Both functions result in a negative number as Excel assumes you intend to subtract the result out of the beginning sum. For the purposes of my test, I thought a negative number looked tacky, so I use the ?ABS? function to return the absolute value of the result.;To make my test sheet more variable, I wanted to allow for a change in the number of years of the loan and the payments per year. As I filled the formulas down to as many cells as it would take for a monthly 30 year loan, I got errors from the payment number exceeding the total number of payments in my original formula so also had to escape the errors by replacing non-number values with a 0 in the calculations. I was able to do this with the standard ?IF? function combined with the ?ISNUMBER? function. Also, in order to allow for a varying number of payments per year, I used the ?DATE? function to calculate the date. This was done by the simple math of adding the appropriate number of months to the original date.;Using these functions was reasonably simple and now I can see what a loan would be when I change any of the terms of the loan. Everything is calculated immediately when I make a change, so looking at a wide variety of options is a simple task. Please check out my test Loan Calculator and let me know what you think. Feel free to play with it and let me know if you have suggestions that would make it even more functional.;Thanks;David;References;Microsoft Corporation. (n.d.). Excel Functions (by Category).

With function EVEN you have the ability to round the number to the nearest even integer. You can use this function for processing items that come in two. Example A packing crate accepts rows of one or two items. The crate is full when the number of items rounded up to the nearest two match the capacity of the crate. And with DOLLARDE you can change a fraction to a dollar sign and most businesses need tools like this because of inventory and the cash.
