Random sampling
Naturalistic study
Which is NOT a step of the scientific method?

Problem
Count items
Draw Conclusions
What is a hypothesis?
an educated guess
an absolute solution
a random guess
an experiment
What does it mean to draw conclusions?
make a guess
test a theory to see if it is true
try something new
use data to make an assumption/theory
What is replication?
cloning the scientist who first did an experiment
doing an experiment for the first time

What is bias?

How can volunteer bias affect the outcome of a study?
It can make others want to volunteer for the study
It can invalidate it, if the volunteers hold bias that is counter to the opinions of those who are not part of the study, but are represented by it
It can split the results in two
It can prove it correct, because volunteer opinions accurately represent everyone in the population
Cross-sectional studies are sometimes more useful than longitudinal studies because they
are more risky
have more variables
cost more money
take less time
Researchers find that there is a significant, positive correlation between the number of hours students sleep and their grades. The researchers would be justified in concluding that...

Sleeping more causes students to perform better in school
Students who earn good grades tend to sleep more than those who do not
More sleep has a beneficial impact on school performance
