scientific process Flashcards
accuracy
how close a measurement is to the true or accepted value
chi-square
test to determine association between 2 or more variables
control
element that remains unchanged by other variables
constant
factor that does not change during the experiment
deductive reasoning
logical thinking that uses general principle or law to forecast specific results
dependent variable
depends on other variables, whats being measured
graph
organized way to show data
hypothesis
an idea that proposes a tentative explanation of a phenomenon observed in the natural world
independent variable
does not change by the variable being. measured
inductive reasoning

mean
sum of all values in data set divided by the number of values
median
middle value of numbers arranged in ascending order
model
no n human species that is studied to understand biological phenomenon
observation
perceiving information from a primary source
precision
how close measurements of the same item are to each other
prediction
says what will happen in an experiment if the hypothesis is correct
rate
the rate or speed a variable changes at
scientific method
the process in which observations are questioned, hypothesis are created and tested, and the results are analyzed
table
a method of organizing numerical information
trend
directional change within a variable
variable
any characteristic which varies from individual to individual
