Different Graphs

 Hi my name is Danh Pham and i will be talking about the different types of graph and what is it useful for! The first i would like to talk about is the bar graph.It is a graph used to compare data. A line graph is a graph used track data through time so it would be great for how much money u gain per month. A circle graph is a graph that you can use for percentages.The histogram is useful when you have a lot of numbers and can be use to display easier. Venn diagram is useful for when you want to see the differences and whats alike. The last graph i would be talking about is the is the line plot which is used when you want to know the frequency data of a certain category.

   Hi my name is Danh Pham and ill will show you positive,negative,no correlation!Lets start with a positive correlation first.Positive correlation is when two things go up for example when the heats goes up the selling of lemonade goes up also!I'll give another example incase you don't understand when the xbox360 sells goes up the xbox360 games go up also because u cant play anything on the xbox360 without the games.Now for negative correlation when one thing goes up the other goes down.When more paper is needed the trees goes down, because you need wood to make paper,Another example is when new technology goes up then they forget the old ones and they go down!Finally but not least no correlation that is when nothing makes sense nothing goes up or down no matter like no relationships at all!For example like your hair and a tree like no relationships because when your hair grows it doesn't mean the trees will go down or grows or like when your hair shortens the trees will shorten.Now i hope you have a understanding or clue what is positive,negative,and no correlation means.
