BOB for October 6, 2009

3 things I learned about graphing:


1. Different types of graphs:


Bar graph - This graph is best for comparing data across categories


Double Bar Graph - This graph is best for comparing two sets of data across categories


Circle Graph - This is best for comparing categories to the whole using percents


Line Graph - This is best for showing changes in data over time


Pictograph - This is best for comparing data that can be easily counted and represented using symbols


2. What needs to be on a graph:


Title - varies on what data you're graphing


Labels - a graph needs to have a label on the x and y axis


Intervals - intervals need to be consistent


x and y axis - x-axis: horizontal line, y-axis: vertical line

Origin - the starting point or also known as the number 0


3. Misrepresenting Data:


Distorting the size - ex. make the size of the bars on a bar graph bigger than the others


Distorting the visual - ex. make the number on a pie graph bigger than the other numbers or by using a bright color so it stands out.


Distorting the scale - ex. put an axis break on graph





What I need to improve on for the assessment:

On my assessment, I need to improve on putting a prediction with my conclusion and explaining a trend.
