Scatter Graphs

!±8± Scatter Graphs

Scatter graph is a graph, which help to plot the information on two related variables. It consists of plotted points, which are scattered all around the X-Y grid. The main use of the scatter graph is to visualize the strength of the co-relation between the two metrics. It can also be said that scatter graphs are used to create the relationship between two variables for a set of paired data. They are mainly used in Science to study relationships between two variables. So it has been found that the pattern of the scatter describes the relationship and the trend lines should follow a trend of the data. Join as many points as possible and leave an equal number of unconnected points on either side.

Scatter graph is a graph, which is like the basic line graphs and require minimum of two numeric data attributes. The pattern of the scatter graph reveals a relationship between the two variables measured by the X and Y axes or in the case of a 3 dimensional form, it will be among the three variables which are measured by X, Y, and Z axes). In a 2 dimensional scatter graphs; one can illustrate trends in the plotted points by just adding a regression curve. It has been noted that the scatter graphs can show multiple data sets, each of which is represented by a different symbol, and each will have any number of data points.

Scatter graph are the one, which clearly establish the data correlation and is one of the best method to illustrate a non-linear pattern. It can be used for data extrapolation and interpolation. A scatter graph generally shows the discrete values which don't occur at regular intervals or which belong to a series. That makes it different from a line graph, which are drawn using only the symbols.

One of the main advantages of a scatter graph is that it demonstrates a typical relationship, which is generally not so clear in various graphing methods normally used. While using standard functions in the Graphics Server DLL, we can define a scatter graph by normally supplying an X position for each data point. It should also be noted that when we use a Graph Control or when we use Graphics Server's autograph DLL, no X positions is supplied and the it will place points at X increments of 1 automatically, starting at 0.

It should be noted that in 3 dimensional (3D) scatter graphs, Z positions are not handled in this way and we needs to supply a Z value for each and every point. We can display scatter plots alone, curves alone, or both while using a 2 dimensional (2D) scatter graphs. While in a 3D scatter graphs, its totally different and we can connect points in the same set with a continuous line. Also we can drop a vertical line from each point.

The limitation of a scatter graph is that, they can just show relationship between two variables at a time. They can also show incorrect graph analysis if there are only few data points available.

Main use of a scatter graph is to visualize the actual measurements or observations on a grid which may reveals patterns and trends (by adding the curves) in those data used on the grid.

Different Boxing Styles

!±8± Different Boxing Styles

While all boxers use different moves, punches and mixtures, there's a precise way in which they fight. This is called their style. There are different kinds of boxing styles. Each varies widely but not totally as one style may seem like a few elements of another style. There are 3 main types or at a minimum, three typically known types of boxing styles, "the boxer", "the slugger", and "the interior fighter. "

The boxer. This is the technical kind of boxing or commonly referred to as the "textbook fighter. " The boxer is a master of both offense and defense. He fights often from the outside, come in to make few hits, and the back off again. The boxer might not be the most entertaining to look at if you are looking for some great action but he has got excellent technical capabilities that beginners can learn from.

He will be able to fight well against sluggers because he is faster and more flexible within the ring. Winky Wright, Muhammad Ali, Sugar Ray Leonard, Floyd Mayweather Jr, Lennox Lewis, Roy Jones Jr, Felix Trinidad and Benny Leonard are some of the most well liked fighters who've got this style.

The slugger. This fighter may not possess the technical abilities of "the boxer " but power and aggressiveness are his main weapons. A slugger is the most fun and most exciting fighter to look at. A. K. A the soldier, he lacks finesse in the ring, but he makes up for it by his unexpectedness and dynamic punches which regularly result to knockouts. This is the reason why Manny Pacquiao is the hottest and well appreciated fighter today. Other well known sluggers are Arturo Gatti, George Foreman, Sonny Liston, and Naseem Hamed.

The interior fighter. This fighter is not as technical as "the boxer " but he's as exciting to look on as the slugger. The inside fighter spends almost all of his time in the ring closing within his adversary and throwing heavy blows of uppercuts and hooks.

He may take some shots on his way in but an insider fighter regularly has a powerful jaw that may resist any likely damages. Some of the hottest inside wrestlers are Joe Frazer, Ricky Hatton, Mike Tyson, Julio Margarito Marco Antonio Barrera, and Julio Cesar Chaves.

There are two other boxing styles that are worth mentioning: half-breed fighter and the crowder.

Boxers may fall into more than one kind of style. This is named the half-breed fighter. There are very good boxers that are considered sluggers but their agility and capability to move round the ring makes in out-fighters. Mike Tyson who is sometimes known as a soldier is a very intense within fighter.

The crowder didn't get his name from his capability to delight the crowd but his ability to put pressure to his adversary inside the ring. Sometimes called the swarmer, this kind of pro boxers put constant pressure to their contestant through unstoppable aggression and attacks. Crowders are a rare type as there are only few fighters who have got great staying power and can continuously attack his competitor throughout the game.

A fighter won't be a crowder throughout in his fight. For example, Manny Pacquiao is considered a slugger but become a crowder in his first fight against Marco Antonio Barrera. Some preferred crowders are Ricky Hatton, Joe Frazer, and Henry Armstrong.

TI 83 Plus Graphing Calculator

!±8± TI 83 Plus Graphing Calculator

The TI 83 Plus Graphing Calculator can do so much for you when it comes to High School Math, as well as College Math classes. If you're in the market to get one today, I wanted to point out why you should get it, and what it can do for you, when it comes to calculating formulas.

Perfect for the ACT, SAT, and PSAT, this handy calculator can do just about anything you can tell it to. In fact, it can even do the formula just like it is in your math book. For example, if you have a problem in your book, you can download the App4Math app and it can figure out the problem for you. There's no more trying to figure out how to do it all on the calculator.

Key features on the TI 83 Plus Graphing Calculator:

It has an upgradable operating system and software, where you can always stay on top of technology, and you don't have to worry about your calculator becoming obsolete.

You can now download study apps like the ones I talked about above. You can compare these to the apps on the systems such as the iPhone. This is great for adding additional software to your phone.

If that's not enough, you can also make it compatible with older editions such as the TI-84 and TI-84 Plus Silver.

With a one year's warranty, it's no wonder why many students tend to take this route when it comes down to getting a calculator for the classroom.
