SULTAN & Graphing Flashcards
What does SULTAN stand for?
Scale, units, label/legend, title. Accuracy, and neatness
True or false: The graph should fill nearly the whole area
True
True or false: Numbers should be evenly spaced
True
Independ variable goes on the _____ axis
X axis
Dependent variable goes on the _____ axis
Y axis
how do you determine scaling on a graph?
- Determine the scale range by subtracting the lowest # from the highest #
- Choose the scale of your graph by counting the # of squares and divide by range. Then round up.
Where do you always label units on the graph?
Along the axis
What is legend?
A graph with more than one sets of data. A place where you can identify what the symbol or color means.
The title should usually be written as….
Dependent variable vs independent variable
Ex. Tempeture of water vs time
The independent variable is…
What we change in the experiment
Ex. Fertilizer (IV) vs growth of plant (DV)
Dependent variable is…
What we measure in the experiment.
Ex. Plant amount gm (IV) vs cholesterol (DV)
What is the dependent variable relying on?
The independent variable
What does the dependent variable have an effect on?
None
DRY MIX
Dependent - responding - y axis
Manipulated - independent - x axis
What are the 5 types of graphs?
Line graph, scatter plot, bar graph, histogram, pie chart
Whats a line graph used for?
A graph only used for change over time
Ex. Plant growth over weeks
What is scatter plot used for?
Correlation of variable (showing average in two sets of data)
What are bar graphs used for?
Only used in comparing groups ( MUST have space between bars)
Ex. Clubs and # of people joined
What are histograms used for?
Distribution of data (NO space between bars)
What are pie charts used for?
Looking at parts of a whole
Ex. Students in echs and what grade their in
The constant is
The variable that remains the same
Ex. Tempeture, pressure, humidity
The control group is….
The test group that’s doesn’t have the IV. It’d used for comparison.
Ex. A child who received no medicine
