Bias means opinion. If something is biased, then it does not have a neutral point of view, it is basically one sided.
To be a journalist, understanding bias is very important. A good journalist would show both sides of the story, and make sure no information is hidden. Also, there cannot be any assumptions. When writing, a journalist should make sure to use only facts, not biased opinions. If they do, then they should make sure to show both sides of the story. This is key to understanding bias.

An example of a journalist using bias is when he or she says the Warriors are going to the NBA Finals. This is not a fact but a biased opinion. To change this phrase, the journalist would say the Warriors have a good chance at making the playoffs, and maybe even the NBA Finals, because of their great record. On the other hand, the team from the East, the Miami Heat, will be a tough team to beat, with the big three of LeBron James, Dwayne Wade, and Chris Bosh.
The concept of bias is a key factor to Journalism, and it shouldn't be used incorrectly. Bias is important in this class because when we are writing, we shouldn't use bias. I will apply the concept of bias to this class by always stating both sides of the story, only using facts, and not making assumptions.
