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.
