what do all graphs have to have?
TAILS:
a title including both variables
an axis (X & Y)
labels (and units if needed)
Intervals
Line of best fit
scale (min and max values are appropriate for the data)
controlled vs. experimental groups
controlled: this group being tested receives no treatment. Normal situation
experimental: The group tested, the group given the treatment.
independent vs. dependent variables
IV: the thing that is being changed/ the one factor you (or the scientist )changed or the big difference between the groups
DV: the result (data) that is observed, collected, and measured
qualitative vs. quantitative
qual: the interpretation based descriptive: observed not measured (bar graph)
quan: numbers based: countable or measureable (line graph)
when trying to find out if not sure, think of the answer to the statement or question
controlled/constant variable
the factor in the experiment that stays the same, something that remains unchanged
X & Y axis
X: independent variable
Y: dependent variable
exponential growth
under idea conditions ( a perfect world with no things to mess with growth of data like disease) grows exponentially and has a J shape on graph
logistic growth
logical shape of data, Population levels off when the capacity of the environment is reached. has an s shape on graph
carrying capacity
there is not enough sustainability or resources /space to be able to have the environment become any more than it is or can be.
monomer
small atoms/molecules that bond together to form more complex structures/chains.
polymer
a substance or material that consists of large molecules(macromolecules). A number of joined monomers
