Graphing #3: Scaling Axes There are a few important steps involved in correctly scaling an axis: STEP 1: Find the range for the variable Range = Largest Value - Smallest Value STEP 2: Divide the range by the number of intervals you want (not too many or too few). We don’t want all of the data smooshed in only part of the graph; spread it out. After dividing, we may need to round to get a number that is easy to count by. (It is up easier to count by 2s instead of 1.9s) STEP 3: Use the rounded number to mark off intervals along the axis. The interval must be the same amount each time (count up by the same number). STEP 1: What is the range of my data? Find the range of the data for each column below. Largest #: _________ Largest #: _________ Largest #: _________ Largest #:___40___ Smallest #:___5___ Smallest #: ________ Smallest #: ________ Smallest #: ________ Range:_35-5 = 35_ Range: ___________ Range: ___________ Range: ___________ STEP 2: What number do I count by? Assume that our graph has 10 intervals (places to put numbers). If needed, round up to get to a good counting number. A) A) B) C) Range = __________ Range = __________ Range = __________ Range = ___35___ # of intervals = _____ # of intervals = # of intervals = # of intervals =__10_ STEP 3: What does my scale look like? Each of the scales for the variables has a dependent few missing values on it. Please fill in any missing values.
