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

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
