Step 1: Understanding the Graph
A Graph is a graphic (such as a chart or diagram) depicting the relationship between two or more variables used, for instance, in visualising scientific data(Wikipedia).
The most common way to display a graphs are like the following, please note that i'm starting out little and growing into more coplex graphs. none will be too extragavent.
*X and Y- Axis (similar to a line graph)
Step 2: The Bar Graph
TO create the graph you would choose a topic, mine was favorite fruits(not shown).
You then choose a set of different items, for instance different fruits.
You then would research your so called topic to help form the graph form, basically finding around so many people and finding out what they like or otherwise.
*note*try to make small graphs, whether it is a small over all number or using a Least common denominator as your incriments on the side.( like the multiples of 5)
Step 3: THe Line Graph
This is similar to the bar graph. The graph shows the same increments on the side, But ALso have increments on the bottom. The source(s) are shown as lines now and show an increase over time or anything else.
The source(s) names are now represented by a key if their is more than one source. if not, the single source is represented by the title.
To create, make the same tally as in the bar graph but as over a lapse of time. you would create the graph as you did exactly like the bar graph, remembering to keep small, and show how the source rices or falls as it goes down the graph
Another graph that you may see is a scatter plot. This is where the sources does not go in the right order.
Step 4: Pie Chart
Now as you probably know, it's not a square anymore, it's a circle. THis graph shows your the portions of a source, naming each portion and stating how much percent it is out of the whole, usually 100%.
To make it... Make a circle to start. Then see how many portions of a source there is. Using a protractor, or a fancy computer application, you would place the specific divisions in proportion of how much percent is use to make the portion. Like cutting the pie... mmmm pie. I'll be back, i got to get some pie now.
Step 5: X-Y Axis Graph
We're back to the squares, but this one has a source that you need to make.
To make it you have a vertical line, a hoorizontal line, and incriment vertically and horizontally ranging from positive infinity to negative infinity.
To put points on the graph you will be given coodinates. These coordinates are stated as (x,y). An example of that is (1,2) that is graphed one right and two up.
Now say that you have 2 points (1,3) and (2,1) and you need to find out what the slope is. to find the slope you first label the coordinates, then follow the second image for the equation, and what you get is slope.
What is you need the Slope- Intercept form, this fun little equation shows the direction that a slope goes and where it starts. this uses one coordinate and a slope.*if you don't have the slope, you can get it now* this equation is the same as the third image.
to get the y-intercept or B, you need a coordinate (x,y) and a slope. then plug in the numbers and find out what B equals. last picture is a good example.
Step 6: Hey, Guess What
it's been really long time since i did the first four but i am avaliable to answer any question or problems if you post them.
This was suppose to be for the burning questions 6.5, hope it still helps
