The 3 things i know about graphing are :
How to make a Bar graph ?
On the left side of the graph ( y-axis ) write down the intervals, it doesn't matter which numbers you start with as long as it goes by the same amount. On the x-axis, you put down the data. It should have the same space. Like if the bar's are spaced out by two, then the rest should be spaced out by two. The bars should be clear, and accurate with the numbers. You have to have labels on the x and y axis to make people understand what your talking about and you need a title that shows what the whole bargraph is about. After you do the information. You have to colour so it stands out.
What are the kinds of graphs ?
Circle graph - Uses percents to compare the other categories.
Line graph - shows change's over time and you can predict the trend more.
Bar graph - Shows the data's numbers
Pictograph- compares data using symbols
How do you misrepresent data?
Colours- adding colours on to one certain piece of the graph can make you think that it's more important than the other pieces.
Distort- makes you focus into one piece more than the other pieces of the graphs.
Breaks- shortens y-axis's appearance
How i can Improve my test mark :
How i can improve my test mark is that i shouldn't forget to put the labels next time and i forgot to put my conclusion for my first graph. I could have predicted the trend of the second graph and i could of told why i misreprensented my bar graph better.
