Objective: How does a scientist set-up the appropriate graph?

 Take the page and divide it into 6 equal boxes  Number the boxes Notes: How to Graph

 Used to show data that continues  Points connected  Show relationship b/w IV and DV.

 Data NOT continuous  Used to COMPARE descriptive data (like amounts or percent)

 Data NOT continuous  Usually data is show as “part of a whole” or as percentages  Categories add up to 100%

 Heating a pan of water over a time period  Shows the number of students earning A’s, B’s, C’s in Biology class  Measuring the percent of each gas in the air  Shows the percentage of allowance spent on different things  Show height change over 16 year period. LINE BAR PIE PIE LINE

 Title: contains IV and DV (Y versus X)  Axis  X-axis = IV  Y-axis = DV  Labeled w/units  Scale  Key (if needed)

Guidelines:  Determined by your data range  Use easy numbers: (1,2,5,10)  Scales on x-axis and y-axis usually not same  DO NOT USE YOUR DATA AS A SCALE!!

Answer the following question in a 2 complete sentence: Why is it important for scientists to graph data that they collect?
