### Subject: Writing

How can you make one essay stand out when 50 other people are writing about the same topic?

Some people feel trapped behind outlines, formats, and topics when writing papers for class. The first lesson is learning how to bring new perspective. No one wants to read something they already know - they want to read something interesting and new! Ask yourself, "What about this topic makes it interesting?" For example, an instructor assigns a class an essay on domestic violence. Ok, what about it? Most of the class will research statistics and the effect it has on the victim and the victim's family. What are some different perspectives to write about? What might have been the cause of the abuser (childhood, substance abuse, depression)? If there are children in the family - how are they affected and what are the lessons being taught to them? Why do some women choose not to report the violence? Look deeper! All of these different angles have endless opportunities to dive deeper and find more meaning and understanding. While grammar and technique have a large impact on a grade, the most important factor is the content. Surprise a professor with something original and your essay is guaranteed to stand out.

### Subject: Statistics

What is a p-value and what does it mean?

The p-value is used in hypothesis testing to determine whether or not the null hypothesis is true. As a general rule, remember the rhyme, "if the P-value is high, the null must fly. If the P-value is low, the null must go." What does this mean? Here is a real life example: I have a deck of 52 cards. How do we determine if this is a regular deck? I'll show you. Say I draw a card at random and get the Jack of spades. The next card I draw is a seven of clubs. I draw another card - 4 of clubs. Seems pretty normal right? I draw two more cards - queen of spades and ace of clubs. Do you think it's strange that I haven't drawn a red card yet? What's the probability of drawing 5 black cards in a row? The probability of drawing 1 black card is 0.5, so (0.5)(0.5)(0.5)(0.5)(0.5) = 0.03125. What if I drew another black card? The probability of 6 black cards in a row is 0.01563. At what point did you become suspicious that my deck wasn't normal? This is why we use the p-value to determine if we should accept the null hypothesis. At first, we assumed that my deck was normal. However, as the probability for the results decreased we began to reject our original hypothesis and believed I did not have a normal deck.

### Subject: Accounting

What is the difference between a debit and a credit?

Picture the accounting equation as a scale. The right side holds all of the asset accounts and liabilities and owner's equity accounts are on the other. Each account has its "normal balance" side to represent an increase or a decrease to that account. All asset accounts have a normal balance as a debit. For example, a debit to Cash means an increase in cash and a credit to cash means a decrease. In order to maintain a balanced scale, the opposite must be true for all liabilities and owner's equity accounts. For instance, a credit to Accounts Payable is an increase to that account and vice versa.
