2. questions
3. hypotheses
4. predictions
5. testing (experiments)
6. conclusion
explain how falsifiability is key to scientific hypotheses. - Answer -falsifiable: can be ruled out
by data
-a hypothesis is never proven
-if false, it is rejected and no longer considered a possible answer to the original question.
-if the data support the hypothesis, it will be accepted until further testing and data show
otherwise.
distinguish null and alternative hypotheses in practical situations - Answer null:
-a hypothesis is always framed as a "null" - which means there is no difference when we do
something.
-example: There is NO DIFFERENCE in the time it takes to drive down University vs. the time it
takes to drive down 16th.
-if we find a difference, we can reject our null hypothesis.
alternative:
-the claim that you're testing
-if we reject the null hypothesis, we can say our alternative hypothesis is true. if we cannot find
this evidence, we will continue with the assumption that the null hypothesis is true.
discuss the value of control groups in designing experiments - Answer -control groups are the
original situation with nothing changed
-one can study the outcome of a situation with no applied variables to it
distinguish quantitative and qualitative data - Answer -quantitative: number or a
measurement
-qualitative: categorical, like color and size
