Lets GRAPH A 6 Step Solution 1 Pick

Let’s GRAPH! A 6 Step Solution

#1 Pick the appropriate graph. n. Remember the tricks… n 1 set of numbers = BAR GRAPH n 2 sets of numbers = LINE GRAPH n. Change over TIME = LINE GRAPH

#1 Pick the appropriate graph. 5 10 15 20 25 54 45 29 25 18

# 2 Find the Independent Variable. n Known before the experiment begins; chosen by the experimenter. n DATA TABLE = 1 st COLUMN n GRAPH = X-AXIS n Label (write) the VARIABLE & UNITS on the X-AXIS.

# 2 Find the Independent Variable. Time (min) Temperature of Coffee (o. C) X

# 3 Find the Dependent Variable. n DATA collected during the experiment; you have to “wait” for this one; what will you write down? n DATA TABLE = 2 nd COLUMN n GRAPH = Y-AXIS n Label (write) the VARIABLE & UNITS on the Y-AXIS.

# 3 Find the Dependent Variable. Time (min) Temperature of Coffee (o. C) Y

#4 Write a TITLE for the graph. Independent Variable vs. Dependent Variable n Remember to write out the complete IV and the complete DV.

#5 Determine the SCALE for the x & y. Ask yourself, “What is the highest number for each axis? ” n Count the number of LINES you have to work with. n n DIVIDE: HIGHEST number Number of LINES Each line should be “worth” this number

#5 Determine the SCALE for the x & y. Highest for the x axis Time (min) Temperature of Coffee (o. C) 5 54 10 45 15 29 20 25 25 18 Highest for the y axis

#6 Add the DATA to the graph. n BAR GRAPH – Bars should be straight, not touching. n LINE GRAPH – Connect the DATA POINTS ONLY; do not connect the line to the origin, unless the origin is part of your data set.
